Carpet

Overview

The carpet trace type is used to create carpet plots, which can be useful for visualizing data across irregular spaces or non-grid-like arrangements. Carpet plots are commonly employed in complex datasets that span two independent variables, such as pressure and temperature or other bivariate datasets.

Carpet traces provide you with control over the X and Y axes, as well as customization of the A and B axes (the independent variables). You can also use a variety of formatting options, including line, color, and axis ticks to enhance the visualization.

Common Uses

Distortion Analysis: Visualizing data across irregular spaces, such as in physics or engineering.
Bivariate Data Visualization: Displaying complex relationships between two independent variables.
Gridless Data Representation: Visualizing data that doesn't fit neatly into grid-like structures.

Alternate to a. Builds a linear space of a coordinates. Use with da where a0 is the starting coordinate and da the step.
An array containing values of the first parameter value
The stride between grid lines along the axis
The starting index of grid lines along the axis
Determines whether or not the range of this axis is computed in relation to the input data. See rangemode for more info. If range is provided, then autorange is set to "false".
Using "strict" a numeric string in trace data is not converted to a number. Using "convert types" a numeric string in trace data may be treated as a number during automatic axis type detection. Defaults to layout.autotypenumbers.
Sets the order in which categories on this axis appear. Only has an effect if categoryorder is set to "array". Used with categoryorder.
Specifies the ordering logic for the case of categorical variables. By default, plotly uses "trace", which specifies the order that is present in the data supplied. Set categoryorder to "category ascending" or "category descending" if order should be determined by the alphanumerical order of the category names. Set categoryorder to "array" to derive the ordering from the attribute categoryarray. If a category is not found in the categoryarray array, the sorting behavior for that attribute will be identical to the "trace" mode. The unspecified categories will follow the categories in categoryarray.
Sets default for all colors associated with this axis all at once: line, font, tick, and grid colors. Grid color is lightened by blending this with the plot background Individual pieces can override this.
The stride between grid lines along the axis
Determines whether or not a line is drawn at along the final value of this axis. If "true", the end line is drawn on top of the grid lines.
Sets the line color of the end line.
Sets the width (in px) of the end line.
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.
Determines whether or not this axis is zoom-able. If true, then zoom is disabled.
Sets the axis line color.
Sets the dash style of lines. Set to a dash type string ("solid", "dot", "dash", "longdash", "dashdot", or "longdashdot") or a dash length list in px (eg "5px,10px,2px,2px").
Sets the width (in px) of the axis line.
Extra padding between label and the axis
Sets a axis label prefix.
Sets a axis label suffix.
Sets the axis line color.
Sets the width (in px) of the axis line.
Hide SI prefix for 10^n if |n| is below this number
Sets the color of the grid lines.
Sets the number of minor grid ticks per major grid tick
Sets the dash style of lines. Set to a dash type string ("solid", "dot", "dash", "longdash", "dashdot", or "longdashdot") or a dash length list in px (eg "5px,10px,2px,2px").
Sets the width (in px) of the grid lines.
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 if tickmode is set to "auto".
Sets the range of this axis. If the axis type is "log", then you must take the log of your desired range (e.g. to set the range from 1 to 100, set the range from 0 to 2). If the axis type is "date", it should be date strings, like date data, though Date objects and unix milliseconds will be accepted and converted to strings. If the axis type is "category", it should be numbers, using the scale where each category is assigned a serial number from zero in the order it appears.
If "normal", the range is computed in relation to the extrema of the input data. If "tozero"`, the range extends to 0, regardless of the input data If "nonnegative", the range is non-negative, regardless of the input data.
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 grid lines are drawn. If "true", the grid lines are drawn at every tick mark.
Determines whether or not a line bounding this axis is drawn.
Determines whether axis labels are drawn on the low side, the high side, both, or neither side of the axis.
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.
Determines whether or not a line is drawn at along the starting value of this axis. If "true", the start line is drawn on top of the grid lines.
Sets the line color of the start line.
Sets the width (in px) of the start line.
The starting index of grid lines along the axis
Sets the angle of the tick labels with respect to the horizontal. For example, a tickangle of -90 draws the tick labels vertically.
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 its dtickrange.
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 this name alongside your modifications (including visible: false or enabled: 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 its name, alongside your modifications (including visible: false or enabled: false to hide it). If there is no template or no matching item, this item will be hidden unless you explicitly show it with visible: true.
string - dtickformat for described zoom level, the same as "tickformat"
Sets a tick label prefix.
Sets a tick label suffix.
Sets the text displayed at the ticks position via tickvals. Only has an effect if tickmode is set to "array". Used with tickvals.
Sets the values at which ticks on this axis appear. Only has an effect if tickmode is set to "array". Used with ticktext.
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".
An additional amount by which to offset the title from the tick labels, given in pixels. Note that this used to be set by the now deprecated titleoffset attribute.
Sets the title of this axis. Note that before the existence of title.text, the title's contents used to be defined as the title attribute itself. This behavior has been deprecated.
Sets the axis type. By default, plotly attempts to determined the axis type by looking into the data of the traces that referenced the axis in question.
Alternate to b. Builds a linear space of a coordinates. Use with db where b0 is the starting coordinate and db the step.
A two dimensional array of y coordinates at each carpet point.
The stride between grid lines along the axis
The starting index of grid lines along the axis
Determines whether or not the range of this axis is computed in relation to the input data. See rangemode for more info. If range is provided, then autorange is set to "false".

Sets the axis type. By default, plotly attempts to determined the axis type by looking into the data of the traces that referenced the axis in question.
An identifier for this carpet, so that scattercarpet and contourcarpet traces can specify a carpet plot on which they lie
The shift applied to each successive row of data in creating a cheater plot. Only used if x is been omitted.
Sets default for all colors associated with this axis all at once: line, font, tick, and grid colors. Grid color is lightened by blending this with the plot background Individual pieces can override this.
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
Sets the a coordinate step. See a0 for more info.
Sets the b coordinate step. See b0 for more info.
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".
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.

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.
Assigns extra meta information associated with this trace that can be used in various text attributes. Attributes such as trace name, graph, axis and colorbar title.text, annotation text rangeselector, updatemenues and sliders label text all support meta. To access the trace meta values in an attribute in the same trace, simply use %{meta[i]} where i is the index or key of the meta item in question. To access trace meta in layout attributes, use %{data[n[.meta[i]} where i is the index or key of the meta and n is the trace index.
Sets the opacity of the trace.
Controls persistence of some user-driven changes to the trace: constraintrange in parcoords traces, as well as some editable: true modifications such as name and colorbar.title. Defaults to layout.uirevision. Note that other user-driven trace attribute changes are controlled by layout attributes: trace.visible is controlled by layout.legend.uirevision, selectedpoints is controlled by layout.selectionrevision, and colorbar.(x|y) (accessible with config: {editable: true}) is controlled by layout.editrevision. Trace changes are tracked by uid, which only falls back on trace index if no uid is provided. So if your app can add/remove traces before the end of the data array, such that the same trace has a different index, you can still preserve user-driven changes if you give each trace a uid that stays with it as it moves.
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).
A two dimensional array of x coordinates at each carpet point. If omitted, the plot is a cheater plot and the xaxis is hidden by default.
Sets a reference between this trace's x coordinates and a 2D cartesian x axis. If "x" (the default value), the x coordinates refer to layout.xaxis. If "x2", the x coordinates refer to layout.xaxis2, and so on.
A two dimensional array of y coordinates at each carpet point.
Sets a reference between this trace's y coordinates and a 2D cartesian y axis. If "y" (the default value), the y coordinates refer to layout.yaxis. If "y2", the y coordinates refer to layout.yaxis2, and so on.
