Treemap
Overview
The treemap
trace type is used to create treemap charts, which visualize hierarchical data through nested rectangles. Each branch of the hierarchy is represented as a rectangle, with smaller rectangles inside representing sub-branches. Treemaps are useful for visualizing part-to-whole relationships and comparing the size of different categories.
You can customize the colors, labels, and hierarchy to represent your data effectively.
Common Uses
- Hierarchical Data Visualization: Displaying nested data as a set of rectangles.
- Part-to-Whole Relationships: Visualizing how different categories contribute to the whole.
- Categorical Data: Showing categorical breakdowns with nested structures.

Unexpected Behavior
The terminal values of a treemap
must be unique. In other words- if you create a treemap with multiple parent-child trees, the values must be unique across all squares that have no children.

- Determines how the items in
values
are summed. When set to "total", items invalues
are taken to be value of all its descendants. When set to "remainder", items invalues
corresponding to the root and the branches sectors are taken to be the extra part not part of the sum of the values at their leaves. - Determines default for
values
when it is not provided, by inferring a 1 for each of the "leaves" and/or "branches", otherwise 0. - Assigns extra data each datum. This may be useful when listening to hover, click and selection events. Note that, "scatter" traces also appends customdata items in the markers DOM elements
- If there is a layout grid, use the domain for this column in the grid for this treemap trace .
- If there is a layout grid, use the domain for this row in the grid for this treemap trace .
- Sets the horizontal domain of this treemap trace (in plot fraction).
- Sets the vertical domain of this treemap trace (in plot fraction).
- Determines which trace information appear on hover. If
none
orskip
are set, no information is displayed upon hovering. But, ifnone
is set, click and hover events are still fired. - Sets the horizontal alignment of the text content within hover label box. Has an effect only if the hover label text spans more two or more lines
- Sets the background color of the hover labels for this trace
- Sets the border color of the hover labels for this trace.
- HTML font family - the typeface that will be applied by the web browser. The web browser will only be able to apply a font if it is available on the system which it operates. Provide multiple font families, separated by commas, to indicate the preference in which to apply fonts if they aren't available on the system. The Chart Studio Cloud (at https://chart-studio.plotly.com or on-premise) generates images on a server, where only a select number of fonts are installed and supported. These include "Arial", "Balto", "Courier New", "Droid Sans",, "Droid Serif", "Droid Sans Mono", "Gravitas One", "Old Standard TT", "Open Sans", "Overpass", "PT Sans Narrow", "Raleway", "Times New Roman".
- Sets the default length (in number of characters) of the trace name in the hover labels for all traces. -1 shows the whole name regardless of length. 0-3 shows the first 0-3 characters, and an integer >3 will show the whole name if it is less than that many characters, but if it is longer, will truncate to
namelength - 3
characters and add an ellipsis. - Template string used for rendering the information that appear on hover box. Note that this will override
hoverinfo
. Variables are inserted using %{variable}, for example "y: %{y}" as well as %{xother}, {%xother}, {%_xother}, {%xother_}. When showing info for several points, "xother" will be added to those with different x positions from the first point. An underscore before or after "(x|y)other" will add a space on that side, only when this field is shown. Numbers are formatted using d3-format's syntax %{variable:d3-format}, for example "Price: %{y:$.2f}". https://github.com/d3/d3-format/tree/v1.4.5#d3-format for details on the formatting syntax. Dates are formatted using d3-time-format's syntax %{variable|d3-time-format}, for example "Day: %{2019-01-01|%A}". https://github.com/d3/d3-time-format/tree/v2.2.3#locale_format for details on the date formatting syntax. The variables available inhovertemplate
are the ones emitted as event data described at this link https://plotly.com/javascript/plotlyjs-events/#event-data. Additionally, every attributes that can be specified per-point (the ones that arearrayOk: true
) are available. variablescurrentPath
,root
,entry
,percentRoot
,percentEntry
andpercentParent
. Anything contained in tag<extra>
is displayed in the secondary box, for example "{fullData.name} ". To hide the secondary box completely, use an empty tag<extra></extra>
. - Sets hover text elements associated with each sector. If a single string, the same string appears for all data points. If an array of string, the items are mapped in order of this trace's sectors. To be seen, trace
hoverinfo
must contain a "text" flag. - Assigns id labels to each datum. These ids for object constancy of data points during animation. Should be an array of strings, not numbers or any other type.
- HTML font family - the typeface that will be applied by the web browser. The web browser will only be able to apply a font if it is available on the system which it operates. Provide multiple font families, separated by commas, to indicate the preference in which to apply fonts if they aren't available on the system. The Chart Studio Cloud (at https://chart-studio.plotly.com or on-premise) generates images on a server, where only a select number of fonts are installed and supported. These include "Arial", "Balto", "Courier New", "Droid Sans",, "Droid Serif", "Droid Sans Mono", "Gravitas One", "Old Standard TT", "Open Sans", "Overpass", "PT Sans Narrow", "Raleway", "Times New Roman".

- Sets the title of the legend group.
- Sets the legend rank for this trace. Items and groups with smaller ranks are presented on top/left side while with
"reversed"
legend.traceorder` they are on bottom/right side. The default legendrank is 1000, so that you can use ranks less than 1000 to place certain items before all unranked items, and ranks greater than 1000 to go after all unranked items. - Sets the width (in px or fraction) of the legend for this trace.
- Sets the level from which this trace hierarchy is rendered. Set
level
to''
to start from the root node in the hierarchy. Must be an "id" ifids
is filled in, otherwise plotly attempts to find a matching item inlabels
. - Determines whether the colorscale is a default palette (
autocolorscale: true
) or the palette determined bymarker.colorscale
. Has an effect only if colors is set to a numerical array. In casecolorscale
is unspecified orautocolorscale
is true, the default palette will be chosen according to whether numbers in thecolor
array are all positive, all negative or mixed. - Determines whether or not the color domain is computed with respect to the input data (here colors) or the bounds set in
marker.cmin
andmarker.cmax
Has an effect only if colors is set to a numerical array. Defaults tofalse
whenmarker.cmin
andmarker.cmax
are set by the user. - Sets the upper bound of the color domain. Has an effect only if colors is set to a numerical array. Value should have the same units as colors and if set,
marker.cmin
must be set as well. - Sets the mid-point of the color domain by scaling
marker.cmin
and/ormarker.cmax
to be equidistant to this point. Has an effect only if colors is set to a numerical array. Value should have the same units as colors. Has no effect whenmarker.cauto
isfalse
. - Sets the lower bound of the color domain. Has an effect only if colors is set to a numerical array. Value should have the same units as colors and if set,
marker.cmax
must be set as well. - Sets a reference to a shared color axis. References to these shared color axes are "coloraxis", "coloraxis2", "coloraxis3", etc. Settings for these shared color axes are set in the layout, under
layout.coloraxis
,layout.coloraxis2
, etc. Note that multiple color scales can be linked to the same color axis. - Sets the color of padded area.
- Sets the axis line color.
- Sets the width (in px) or the border enclosing this color bar.
- Sets the step in-between ticks on this axis. Use with
tick0
. Must be a positive number, or special strings available to "log" and "date" axes. If the axistype
is "log", then ticks are set every 10^(n"dtick) where n is the tick number. For example, to set a tick mark at 1, 10, 100, 1000, ... set dtick to 1. To set tick marks at 1, 100, 10000, ... set dtick to 2. To set tick marks at 1, 5, 25, 125, 625, 3125, ... set dtick to log_10(5), or 0.69897000433. "log" has several special values; "L", where f
is a positive number, gives ticks linearly spaced in value (but not position). For exampletick0
= 0.1,dtick
= "L0.5" will put ticks at 0.1, 0.6, 1.1, 1.6 etc. To show powers of 10 plus small digits between, use "D1" (all digits) or "D2" (only 2 and 5).tick0
is ignored for "D1" and "D2". If the axistype
is "date", then you must convert the time to milliseconds. For example, to set the interval between ticks to one day, setdtick
to 86400000.0. "date" also has special values "M" gives ticks spaced by a number of months. n
must be a positive integer. To set ticks on the 15th of every third month, settick0
to "2000-01-15" anddtick
to "M3". To set ticks every 4 years, setdtick
to "M48" - Determines a formatting rule for the tick exponents. For example, consider the number 1,000,000,000. If "none", it appears as 1,000,000,000. If "e", 1e+9. If "E", 1E+9. If "power", 1x10^9 (with 9 in a super script). If "SI", 1G. If "B", 1B.
- Sets the length of the color bar This measure excludes the padding of both ends. That is, the color bar length is this length minus the padding on both ends.
- Determines whether this color bar's length (i.e. the measure in the color variation direction) is set in units of plot "fraction" or in "pixels. Use
len
to set the value. - Hide SI prefix for 10^n if |n| is below this number. This only has an effect when
tickformat
is "SI" or "B". - Specifies the maximum number of ticks for the particular axis. The actual number of ticks will be chosen automatically to be less than or equal to
nticks
. Has an effect only iftickmode
is set to "auto". - Sets the orientation of the colorbar.
- Sets the axis line color.
- Sets the width (in px) of the axis line.
- If "true", even 4-digit integers are separated
- If "all", all exponents are shown besides their significands. If "first", only the exponent of the first tick is shown. If "last", only the exponent of the last tick is shown. If "none", no exponents appear.
- Determines whether or not the tick labels are drawn.
- If "all", all tick labels are displayed with a prefix. If "first", only the first tick is displayed with a prefix. If "last", only the last tick is displayed with a suffix. If "none", tick prefixes are hidden.
- Same as
showtickprefix
but for tick suffixes. - Sets the thickness of the color bar This measure excludes the size of the padding, ticks and labels.
- Determines whether this color bar's thickness (i.e. the measure in the constant color direction) is set in units of plot "fraction" or in "pixels". Use
thickness
to set the value. - Sets the placement of the first tick on this axis. Use with
dtick
. If the axistype
is "log", then you must take the log of your starting tick (e.g. to set the starting tick to 100, set thetick0
to 2) except whendtick
="L" (see dtick
for more info). If the axistype
is "date", it should be a date string, like date data. If the axistype
is "category", it should be a number, using the scale where each category is assigned a serial number from zero in the order it appears. - Sets the angle of the tick labels with respect to the horizontal. For example, a
tickangle
of -90 draws the tick labels vertically. - Sets the tick color.
- HTML font family - the typeface that will be applied by the web browser. The web browser will only be able to apply a font if it is available on the system which it operates. Provide multiple font families, separated by commas, to indicate the preference in which to apply fonts if they aren't available on the system. The Chart Studio Cloud (at https://chart-studio.plotly.com or on-premise) generates images on a server, where only a select number of fonts are installed and supported. These include "Arial", "Balto", "Courier New", "Droid Sans",, "Droid Serif", "Droid Sans Mono", "Gravitas One", "Old Standard TT", "Open Sans", "Overpass", "PT Sans Narrow", "Raleway", "Times New Roman".
- Sets the tick label formatting rule using d3 formatting mini-languages which are very similar to those in Python. For numbers, see: https://github.com/d3/d3-format/tree/v1.4.5#d3-format. And for dates see: https://github.com/d3/d3-time-format/tree/v2.2.3#locale_format. We add two items to d3's date formatter: "%h" for half of the year as a decimal number as well as "%{n}f" for fractional seconds with n digits. For example, "2016-10-13 09:15:23.456" with tickformat "%H~%M~%S.%2f" would display "09~15~23.46"
- range ["min", "max"], where "min", "max" - dtick values which describe some zoom level, it is possible to omit "min" or "max" value by passing "null"
- Determines whether or not this stop is used. If
false
, this stop is ignored even within itsdtickrange
. - When used in a template, named items are created in the output figure in addition to any items the figure already has in this array. You can modify these items in the output figure by making your own item with
templateitemname
matching thisname
alongside your modifications (includingvisible: false
orenabled: false
to hide it). Has no effect outside of a template. - Used to refer to a named item in this array in the template. Named items from the template will be created even without a matching item in the input figure, but you can modify one by making an item with
templateitemname
matching itsname
, alongside your modifications (includingvisible: false
orenabled: false
to hide it). If there is no template or no matching item, this item will be hidden unless you explicitly show it withvisible: true
. - string - dtickformat for described zoom level, the same as "tickformat"
- Determines how we handle tick labels that would overflow either the graph div or the domain of the axis. The default value for inside tick labels is "hide past domain". In other cases the default is "hide past div".
- Determines where tick labels are drawn relative to the ticks. Left and right options are used when
orientation
is "h", top and bottom whenorientation
is "v". - Sets the spacing between tick labels as compared to the spacing between ticks. A value of 1 (default) means each tick gets a label. A value of 2 means shows every 2nd label. A larger value n means only every nth tick is labeled.
tick0
determines which labels are shown. Not implemented for axes withtype
"log" or "multicategory", or whentickmode
is "array". - Sets the tick length (in px).
- Sets the tick mode for this axis. If "auto", the number of ticks is set via
nticks
. If "linear", the placement of the ticks is determined by a starting positiontick0
and a tick stepdtick
("linear" is the default value iftick0
anddtick
are provided). If "array", the placement of the ticks is set viatickvals
and the tick text isticktext
. ("array" is the default value iftickvals
is provided). - Sets a tick label prefix.
- Determines whether ticks are drawn or not. If "", this axis' ticks are not drawn. If "outside" ("inside"), this axis' are drawn outside (inside) the axis lines.
- Sets a tick label suffix.
- Sets the text displayed at the ticks position via
tickvals
. Only has an effect iftickmode
is set to "array". Used withtickvals
. - Sets the values at which ticks on this axis appear. Only has an effect if
tickmode
is set to "array". Used withticktext
. - Sets the tick width (in px).

These include "Arial", "Balto", "Courier New", "Droid Sans",, "Droid Serif", "Droid Sans Mono", "Gravitas One", "Old Standard TT", "Open Sans", "Overpass", "PT Sans Narrow", "Raleway", "Times New Roman".
- Determines the location of color bar's title with respect to the color bar. Defaults to "top" when
orientation
if "v" and defaults to "right" whenorientation
if "h". Note that the title's location used to be set by the now deprecatedtitleside
attribute. - Sets the title of the color bar. Note that before the existence of
title.text
, the title's contents used to be defined as thetitle
attribute itself. This behavior has been deprecated. - Sets the x position of the color bar (in plot fraction). Defaults to 1.02 when
orientation
is "v" and 0.5 whenorientation
is "h". - Sets this color bar's horizontal position anchor. This anchor binds the
x
position to the "left", "center" or "right" of the color bar. Defaults to "left" whenorientation
is "v" and "center" whenorientation
is "h". - Sets the amount of padding (in px) along the x direction.
- Sets the y position of the color bar (in plot fraction). Defaults to 0.5 when
orientation
is "v" and 1.02 whenorientation
is "h". - Sets this color bar's vertical position anchor This anchor binds the
y
position to the "top", "middle" or "bottom" of the color bar. Defaults to "middle" whenorientation
is "v" and "bottom" whenorientation
is "h". - Sets the amount of padding (in px) along the y direction.
- Sets the color of each sector of this trace. If not specified, the default trace color set is used to pick the sector colors.
- Sets the colorscale. Has an effect only if colors is set to a numerical array. The colorscale must be an array containing arrays mapping a normalized value to an rgb, rgba, hex, hsl, hsv, or named color string. At minimum, a mapping for the lowest (0) and highest (1) values are required. For example,
[[0, 'rgb(0,0,255)'], [1, 'rgb(255,0,0)']]
. To control the bounds of the colorscale in color space, usemarker.cmin
andmarker.cmax
. Alternatively,colorscale
may be a palette name string of the following list: Blackbody,Bluered,Blues,Cividis,Earth,Electric,Greens,Greys,Hot,Jet,Picnic,Portland,Rainbow,RdBu,Reds,Viridis,YlGnBu,YlOrRd. - Sets the maximum rounding of corners (in px).
- Determines if the sector colors are faded towards the background from the leaves up to the headers. This option is unavailable when a
colorscale
is present, defaults to false whenmarker.colors
is set, but otherwise defaults to true. When set to "reversed", the fading direction is inverted, that is the top elements within hierarchy are drawn with fully saturated colors while the leaves are faded towards the background color. - Sets the color of the line enclosing each sector. Defaults to the
paper_bgcolor
value. - Sets the width (in px) of the line enclosing each sector.
- Sets the padding form the bottom (in px).
- Sets the padding form the left (in px).
- Sets the padding form the right (in px).
- Sets the padding form the top (in px).
- Reverses the color mapping if true. Has an effect only if colors is set to a numerical array. If true,
marker.cmin
will correspond to the last color in the array andmarker.cmax
will correspond to the first color. - Determines whether or not a colorbar is displayed for this trace. Has an effect only if colors is set to a numerical array.
- Sets the number of rendered sectors from any given
level
. Setmaxdepth
to "-1" to render all the levels in the hierarchy. - Assigns extra meta information associated with this trace that can be used in various text attributes. Attributes such as trace
name
, graph, axis and colorbartitle.text
, annotationtext
rangeselector
,updatemenues
andsliders
label
text all supportmeta
. To access the tracemeta
values in an attribute in the same trace, simply use%{meta[i]}
wherei
is the index or key of themeta
item in question. To access tracemeta
in layout attributes, use%{data[n[.meta[i]}
wherei
is the index or key of themeta
andn
is the trace index. - Sets the opacity of the trace.
- HTML font family - the typeface that will be applied by the web browser. The web browser will only be able to apply a font if it is available on the system which it operates. Provide multiple font families, separated by commas, to indicate the preference in which to apply fonts if they aren't available on the system. The Chart Studio Cloud (at https://chart-studio.plotly.com or on-premise) generates images on a server, where only a select number of fonts are installed and supported. These include "Arial", "Balto", "Courier New", "Droid Sans",, "Droid Serif", "Droid Sans Mono", "Gravitas One", "Old Standard TT", "Open Sans", "Overpass", "PT Sans Narrow", "Raleway", "Times New Roman".
- Sets the parent sectors for each of the sectors. Empty string items '' are understood to reference the root node in the hierarchy. If
ids
is filled,parents
items are understood to be "ids" themselves. Whenids
is not set, plotly attempts to find matching items inlabels
, but beware they must be unique. - Determines which shape is used for edges between
barpath
labels. - Determines on which side of the the treemap the
pathbar
should be presented. - HTML font family - the typeface that will be applied by the web browser. The web browser will only be able to apply a font if it is available on the system which it operates.

- Sets the thickness of
pathbar
(in px). If not specified thepathbar.textfont.size
is used with 3 pixles extra padding on each side. - Determines if the path bar is drawn i.e. outside the trace
domain
and with one pixel gap. - sets the color of the root node for a sunburst/treemap/icicle trace. this has no effect when a colorscale is used to set the markers.
- Determines whether or not the sectors are reordered from largest to smallest.
- Sets text elements associated with each sector. If trace
textinfo
contains a "text" flag, these elements will be seen on the chart. If tracehoverinfo
contains a "text" flag and "hovertext" is not set, these elements will be seen in the hover labels. - HTML font family - the typeface that will be applied by the web browser.

- Determines which trace information appear on the graph.
- Sets the positions of the
text
elements. - Template string used for rendering the information text that appear on points. Note that this will override
textinfo
. Variables are inserted using %{variable}, for example "y: %{y}". Numbers are formatted using d3-format's syntax %{variable:d3-format}, for example "Price: %{y:$.2f}". https://github.com/d3/d3-format/tree/v1.4.5#d3-format for details on the formatting syntax. Dates are formatted using d3-time-format's syntax %{variable|d3-time-format}, for example "Day: %{2019-01-01|%A}". https://github.com/d3/d3-time-format/tree/v2.2.3#locale_format for details on the date formatting syntax.

. - Determines if the positions obtained from solver are flipped on each axis.
- Determines d3 treemap solver. For more info please refer to https://github.com/d3/d3-hierarchy#treemap-tiling
- Sets the inner padding (in px).
- When using "squarify"
packing
algorithm, according to https://github.com/d3/d3-hierarchy/blob/v3.1.1/README.md#squarify_ratio this option specifies the desired aspect ratio of the generated rectangles. The ratio must be specified as a number greater than or equal to one. Note that the orientation of the generated rectangles (tall or wide) is not implied by the ratio; for example, a ratio of two will attempt to produce a mixture of rectangles whose width:height ratio is either 2:1 or 1:2. When using "squarify", unlike d3 which uses the Golden Ratio i.e. 1.618034, Plotly applies 1 to increase squares in treemap layouts. - Controls persistence of some user-driven changes to the trace:
constraintrange
inparcoords
traces, as well as someeditable: true
modifications such asname
andcolorbar.title
. Defaults tolayout.uirevision
. Note that other user-driven trace attribute changes are controlled bylayout
attributes:trace.visible
is controlled bylayout.legend.uirevision
,selectedpoints
is controlled bylayout.selectionrevision
, andcolorbar.(x|y)
(accessible withconfig: {editable: true}
) is controlled bylayout.editrevision
. Trace changes are tracked byuid
, which only falls back on trace index if nouid
is provided. So if your app can add/remove traces before the end of thedata
array, such that the same trace has a different index, you can still preserve user-driven changes if you give each trace auid
that stays with it as it moves. - Sets the values associated with each of the sectors. Use with
branchvalues
to determine how the values are summed. - Determines whether or not this trace is visible. If "legendonly", the trace is not drawn, but can appear as a legend item (provided that the legend itself is visible).
