Add a new Contour trace

The data from which contour lines are computed is set in z. Data in z must be a 2D list of numbers. Say that z has N rows and M columns, then by default, these N rows correspond to N y coordinates (set in y or auto-generated) and the M columns correspond to M x coordinates (set in x or auto- generated). By setting transpose to True, the above behavior is flipped.

Parameters

  • autocolorscale – Determines whether the colorscale is a default palette (autocolorscale: true) or the palette determined by colorscale. In case colorscale is unspecified or autocolorscale is true, the default palette will be chosen according to whether numbers in the color array are all positive, all negative or mixed.

  • autocontour – Determines whether or not the contour level attributes are picked by an algorithm. If True, the number of contour levels can be set in ncontours. If False, set the contour level attributes in contours.

  • coloraxis – 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.

  • colorbar – plotly.graph_objects.contour.ColorBar instance or dict with compatible properties

  • colorscale – Sets the colorscale. 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, use`zmin` and zmax. Alternatively, colorscale may be a palette name string of the following list: Greys,YlGnBu,Greens,YlOrR d,Bluered,RdBu,Reds,Blues,Picnic,Rainbow,Portland,Jet,H ot,Blackbody,Earth,Electric,Viridis,Cividis.

  • connectgaps – Determines whether or not gaps (i.e. {nan} or missing values) in the z data are filled in. It is defaulted to true if z is a one dimensional array otherwise it is defaulted to false.

  • contours – plotly.graph_objects.contour.Contours instance or dict with compatible properties

  • customdata – 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

  • customdatasrc – Sets the source reference on Chart Studio Cloud for customdata .

  • dx – Sets the x coordinate step. See x0 for more info.

  • dy – Sets the y coordinate step. See y0 for more info.

  • fillcolor – Sets the fill color if contours.type is “constraint”. Defaults to a half-transparent variant of the line color, marker color, or marker line color, whichever is available.

  • hoverinfo – Determines which trace information appear on hover. If none or skip are set, no information is displayed upon hovering. But, if none is set, click and hover events are still fired.

  • hoverinfosrc – Sets the source reference on Chart Studio Cloud for hoverinfo .

  • hoverlabel – plotly.graph_objects.contour.Hoverlabel instance or dict with compatible properties

  • hoverongaps – Determines whether or not gaps (i.e. {nan} or missing values) in the z data have hover labels associated with them.

  • hovertemplate – 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}”. Numbers are formatted using d3-format’s syntax %{variable:d3-format}, for example “Price: %{y:$.2f}”. https://github.com/d3/d3-3.x-api- reference/blob/master/Formatting.md#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#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. Additionally, every attributes that can be specified per-point (the ones that are arrayOk: true) are available. Anything contained in tag <extra> is displayed in the secondary box, for example “<extra>{fullData.name}</extra>”. To hide the secondary box completely, use an empty tag <extra></extra>.

  • hovertemplatesrc – Sets the source reference on Chart Studio Cloud for hovertemplate .

  • hovertext – Same as text.

  • hovertextsrc – Sets the source reference on Chart Studio Cloud for hovertext .

  • ids – 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.

  • idssrc – Sets the source reference on Chart Studio Cloud for ids .

  • legendgroup – Sets the legend group for this trace. Traces part of the same legend group hide/show at the same time when toggling legend items.

  • line – plotly.graph_objects.contour.Line instance or dict with compatible properties

  • meta – 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.

  • metasrc – Sets the source reference on Chart Studio Cloud for meta .

  • name – Sets the trace name. The trace name appear as the legend item and on hover.

  • ncontours – Sets the maximum number of contour levels. The actual number of contours will be chosen automatically to be less than or equal to the value of ncontours. Has an effect only if autocontour is True or if contours.size is missing.

  • opacity – Sets the opacity of the trace.

  • reversescale – Reverses the color mapping if true. If true, zmin will correspond to the last color in the array and zmax will correspond to the first color.

  • showlegend – Determines whether or not an item corresponding to this trace is shown in the legend.

  • showscale – Determines whether or not a colorbar is displayed for this trace.

  • stream – plotly.graph_objects.contour.Stream instance or dict with compatible properties

  • text – Sets the text elements associated with each z value.

  • textsrc – Sets the source reference on Chart Studio Cloud for text .

  • transpose – Transposes the z data.

  • uid – Assign an id to this trace, Use this to provide object constancy between traces during animations and transitions.

  • uirevision – 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.

  • visible – 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).

  • xperiod – Only relevant when the axis type is “date”. Sets the period positioning in milliseconds or “M<n>” on the x axis. Special values in the form of “M<n>” could be used to declare the number of months. In this case n must be a positive integer.

  • xperiod0 – Only relevant when the axis type is “date”. Sets the base for period positioning in milliseconds or date string on the x0 axis. When x0period is round number of weeks, the x0period0 by default would be on a Sunday i.e. 2000-01-02, otherwise it would be at 2000-01-01.

  • xsrc – Sets the source reference on Chart Studio Cloud for x .

  • xtype – If “array”, the heatmap’s x coordinates are given by “x” (the default behavior when x is provided). If “scaled”, the heatmap’s x coordinates are given by “x0” and “dx” (the default behavior when x is not provided).

  • y – Sets the y coordinates.

  • y0 – Alternate to y. Builds a linear space of y coordinates. Use with dy where y0 is the starting coordinate and dy the step.

  • yaxis – 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.
