Scatter (line, area & scatter)

Overview

The scatter trace type is used to create scatter plots, which visualize data points based on two numerical variables. Scatter plots are widely used for analyzing relationships between variables, identifying trends, and detecting outliers.

Gotchas

  1. Scatter traces are also used to generate area and line traces.
  2. The line connections of a scatter trace are determined by the trace.order_by attribute. Make sure to set that to get a deterministic trace for lines and area permutations.

You can customize the marker size, color, and add lines to connect the points to represent the data in various forms like scatter plots, line charts, and more.

Common Uses

  • Relationship Analysis: Exploring the relationship between two variables.
  • Trend Detection: Identifying trends or patterns in data.
  • Outlier Identification: Spotting outliers in data distributions.

Common Configurations

Here's a simple scatter plot showing data points on a 2D plane:

You can copy this code below to create this chart in your project:

models:
  - name: scatter-data
    args:
      - echo
      - |
        x,y
        1,10

  1. Set several traces linked to the same position axis or matching axes to the same alignmentgroup. This controls whether bars compute their positional range dependently or independently.
  2. Determines whether or not markers and text nodes are clipped about the subplot axes. To show markers and text nodes above axis lines and tick labels, make sure to set xaxis.layer and yaxis.layer to below traces.
  3. Determines whether or not gaps (i.e. {nan} or missing values) in the provided data arrays are connected.
  4. 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
  5. Sets the source reference on Chart Studio Cloud for customdata.
  6. Sets the x coordinate step. See x0 for more info.
  7. Sets the y coordinate step. See y0 for more info.
  8. Sets the data corresponding the length of each error bar. Values are plotted relative to the underlying data.
  9. Sets the data corresponding the length of each error bar in the bottom (left) direction for vertical (horizontal) bars Values are plotted relative to the underlying data.
  10. Sets the source reference on Chart Studio Cloud for arrayminus.
  11. Sets the source reference on Chart Studio Cloud for array.
  12. Sets the stroke color of the error bars.
  13. Determines whether or not the error bars have the same length in both direction (top/bottom for vertical bars, left/right for horizontal bars.
  14. Sets the thickness (in px) of the error bars.
  15. Determines the rule used to generate the error bars. If *constant, the bar lengths are of a constant value. Set this constant invalue. If *percent*, the bar lengths correspond to a percentage of underlying data. Set this percentage invalue. If *sqrt*, the bar lengths correspond to the square of the underlying data. If *data*, the bar lengths are set with data setarray`.
  16. Sets the value of either the percentage (if type is set to percent) or the constant (if type is set to constant) corresponding to the lengths of the error bars.
  17. Sets the value of either the percentage (if type is set to percent) or the constant (if type is set to constant) corresponding to the lengths of the error bars in the bottom (left) direction for vertical (horizontal) bars
  18. Determines whether or not this set of error bars is visible.
  19. Sets the width (in px) of the cross-bar at both ends of the error bars.
  20. Sets the data corresponding the length of each error bar. Values are plotted relative to the underlying data.
  21. Sets the data corresponding the length of each error bar in the bottom (left) direction for vertical (horizontal) bars Values are plotted relative to the underlying data.
  22. Sets the source reference on Chart Studio Cloud for arrayminus.
  23. Sets the source reference on Chart Studio Cloud for array.
  24. Sets the stroke color of the error bars.
  25. Determines whether or not the error bars have the same length in both direction (top/bottom for vertical bars, left/right for horizontal bars.
  26. Sets the thickness (in px) of the error bars.
  27. Determines the rule used to generate the error bars. If *constant, the bar lengths are of a constant value. Set this constant invalue. If *percent*, the bar lengths correspond to a percentage of underlying data. Set this percentage invalue. If *sqrt*, the bar lengths correspond to the square of the underlying data. If *data*, the bar lengths are set with data setarray`.
  28. Sets the value of either the percentage (if type is set to percent) or the constant (if type is set to constant) corresponding to the lengths of the error bars.
  29. Sets the value of either the percentage (if type is set to percent) or the constant (if type is set to constant) corresponding to the lengths of the error bars in the bottom (left) direction for vertical (horizontal) bars
  30. Determines whether or not this set of error bars is visible.
  31. Sets the width (in px) of the cross-bar at both ends of the error bars.
  32. Sets the area to fill with a solid color. Defaults to none unless this trace is stacked, then it gets tonexty (tonextx) if orientation is v (h) Use with fillcolor if not none. tozerox and tozeroy fill to x=0 and y=0 respectively. tonextx and tonexty fill between the endpoints of this trace and the endpoints of the trace before it, connecting those endpoints with straight lines (to make a stacked area graph); if there is no trace before it, they behave like tozerox and tozeroy. toself connects the endpoints of the trace (or each segment of the trace if it has gaps) into a closed shape. tonext fills the space between two traces if one completely encloses the other (eg consecutive contour lines), and behaves like toself if there is no trace before it. tonext should not be used if one trace does not enclose the other. Traces in a stackgroup will only fill to (or be filled to) other traces in the same group. With multiple stackgroups or some traces stacked and some not, if fill-linked traces are not already consecutive, the later ones will be pushed down in the drawing order.
  33. Sets the fill color. Defaults to a half-transparent variant of the line color, marker color, or marker line color, whichever is available. If fillgradient is specified, fillcolor is ignored except for setting the background color of the hover label, if any.
  34. Sets the fill gradient colors as a color scale. The color scale is interpreted as a gradient applied in the direction specified by orientation, from the lowest to the highest value of the scatter plot along that axis, or from the center to the most distant point from it, if orientation is radial.
  35. Sets the gradient start value. It is given as the absolute position on the axis determined by the orientation. E.g., if orientation is horizontal, the gradient will be horizontal and start from the x-position given by start. If omitted, the gradient starts at the lowest value of the trace along the respective axis. Ignored if orientation is radial.
  36. Sets the gradient end value. It is given as the absolute position on the axis determined by the orientation. E.g., if orientation is horizontal, the gradient will be horizontal and end at the x-position given by end. If omitted, the gradient ends at the highest value of the trace along the respective axis. Ignored if orientation is radial.
  37. Sets the type/orientation of the color gradient for the fill. Defaults to none.
  38. When there is no colorscale sets the color of background pattern fill. Defaults to a marker.color background when fillmode is overlay. Otherwise, defaults to a transparent background.
  39. Sets the source reference on Chart Studio Cloud for bgcolor.
  40. When there is no colorscale sets the color of foreground pattern fill. Defaults to a marker.color background when fillmode is replace. Otherwise, defaults to dark grey or white to increase contrast with the bgcolor.
  41. Sets the source reference on Chart Studio Cloud for fgcolor.
  42. Sets the opacity of the foreground pattern fill. Defaults to a 0.5 when fillmode is overlay. Otherwise, defaults to 1.
  43. Determines whether marker.color should be used as a default to bgcolor or a fgcolor.
  44. Sets the shape of the pattern fill. By default, no pattern is used for filling the area.
  45. Sets the source reference on Chart Studio Cloud for shape.
  46. Sets the size of unit squares of the pattern fill in pixels, which corresponds to the interval of repetition of the pattern.
  47. Sets the source reference on Chart Studio Cloud for size.
  48. Sets the solidity of the pattern fill. Solidity is roughly the fraction of the area filled by the pattern. Solidity of 0 shows only the background color without pattern and solidty of 1 shows only the foreground color without pattern.
  49. Sets the source reference on Chart Studio Cloud for solidity.
  50. Only relevant when stackgroup is used, and only the first groupnorm found in the stackgroup will be used - including if visible is legendonly but not if it is false. Sets the normalization for the sum of this stackgroup. With fraction, the value of each trace at each location is divided by the sum of all trace values at that location. percent is the same but multiplied by 100 to show percentages.

  76. Sets the source reference on Chart Studio Cloud for namelength.
  77. Do the hover effects highlight individual points (markers or line points) or do they highlight filled regions? If the fill is toself or tonext and there are no markers or text, then the default is fills, otherwise it is points.
  78. 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 in hovertemplate are the ones emitted as event data described at this link https://plotly.com/javascript/plotlyjs-events/#event-data.

With interpolate we linearly interpolate between existing values, and extrapolate a constant beyond the existing values.
  216. Set several scatter traces (on the same subplot) to the same stackgroup in order to add their y values (or their x values if orientation is h). If blank or omitted this trace will not be stacked. Stacking also turns fill on by default, using tonexty (tonextx) if orientation is h (v) and sets the default mode to lines irrespective of point count. You can only stack on a numeric (linear or log) axis. Traces in a stackgroup will only fill to (or be filled to) other traces in the same group.

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. Every attributes that can be specified per-point (the ones that are arrayOk: true) are available.
  240. Sets the source reference on Chart Studio Cloud for texttemplate.
  241. Assign an id to this trace, Use this to provide object constancy between traces during animations and transitions.
  242. Sets the marker color of unselected points, applied only when a selection exists.
  243. Sets the marker opacity of unselected points, applied only when a selection exists.
  244. Sets the marker size of unselected points, applied only when a selection exists.
  245. Sets the text font color of unselected points, applied only when a selection exists.
  246. 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).
  247. Sets the x coordinates.
  248. 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.
  249. Sets the calendar system to use with x date data.
  250. Sets the hover text formatting rulefor x 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 09~15~23.46By default the values are formatted using xaxis.hoverformat.
  251. Only relevant when the axis type is date. Sets the alignment of data points on the x axis.
  252. Sets the source reference on Chart Studio Cloud for x.
  253. Sets the y coordinates.
  254. 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.
  255. Sets the calendar system to use with y date data.
  256. Sets the hover text formatting rulefor y 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.

For example, 2016-10-13 09:15:23.456 with tickformat %H~%M~%S.%2f would display 09~15~23.46By default the values are formatted using yaxis.hoverformat.
  257. Only relevant when the axis type is date. Sets the alignment of data points on the y axis.
  258. Sets the source reference on Chart Studio Cloud for y.
  259. Sets the layer on which this trace is displayed, relative to other SVG traces on the same subplot. SVG traces with higher zorder appear in front of those with lower zorder.
