Add a new Mesh3d trace

Draws sets of triangles with coordinates given by three 1-dimensional arrays in x, y, z and (1) a sets of i, j, k indices (2) Delaunay triangulation or (3) the Alpha- shape algorithm or (4) the Convex-hull algorithm

Parameters
  • alphahull – Determines how the mesh surface triangles are derived from the set of vertices (points) represented by the x, y and z arrays, if the i, j, k arrays are not supplied. For general use of mesh3d it is preferred that i, j, k are supplied. If “-1”, Delaunay triangulation is used, which is mainly suitable if the mesh is a single, more or less layer surface that is perpendicular to delaunayaxis. In case the delaunayaxis intersects the mesh surface at more than one point it will result triangles that are very long in the dimension of delaunayaxis. If “>0”, the alpha-shape algorithm is used. In this case, the positive alphahull value signals the use of the alpha-shape algorithm, _and_ its value acts as the parameter for the mesh fitting. If 0, the convex-hull algorithm is used. It is suitable for convex bodies or if the intention is to enclose the x, y and z point set into a convex hull.

  • 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.

  • cauto – Determines whether or not the color domain is computed with respect to the input data (here intensity) or the bounds set in cmin and cmax Defaults to false when cmin and cmax are set by the user.

  • cmax – Sets the upper bound of the color domain. Value should have the same units as intensity and if set, cmin must be set as well.

  • cmid – Sets the mid-point of the color domain by scaling cmin and/or cmax to be equidistant to this point. Value should have the same units as intensity. Has no effect when cauto is false.

  • cmin – Sets the lower bound of the color domain. Value should have the same units as intensity and if set, cmax must be set as well.

  • color – Sets the color of the whole mesh

  • 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.

  • colorbarplotly.graph_objects.mesh3d.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`cmin` and cmax. 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.

  • contourplotly.graph_objects.mesh3d.Contour 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 .

  • delaunayaxis – Sets the Delaunay axis, which is the axis that is perpendicular to the surface of the Delaunay triangulation. It has an effect if i, j, k are not provided and alphahull is set to indicate Delaunay triangulation.

  • facecolor – Sets the color of each face Overrides “color” and “vertexcolor”.

  • facecolorsrc – Sets the source reference on Chart Studio Cloud for facecolor .

  • flatshading – Determines whether or not normal smoothing is applied to the meshes, creating meshes with an angular, low- poly look via flat reflections.

  • 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 .

  • hoverlabelplotly.graph_objects.mesh3d.Hoverlabel instance or dict with compatible properties

  • 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 .

  • i – A vector of vertex indices, i.e. integer values between 0 and the length of the vertex vectors, representing the “first” vertex of a triangle. For example, {i[m], j[m], k[m]} together represent face m (triangle m) in the mesh, where i[m] = n points to the triplet {x[n], y[n], z[n]} in the vertex arrays. Therefore, each element in i represents a point in space, which is the first vertex of a triangle.

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

  • intensity – Sets the intensity values for vertices or cells as defined by intensitymode. It can be used for plotting fields on meshes.

  • intensitymode – Determines the source of intensity values.

  • intensitysrc – Sets the source reference on Chart Studio Cloud for intensity .

  • isrc – Sets the source reference on Chart Studio Cloud for i .

  • j – A vector of vertex indices, i.e. integer values between 0 and the length of the vertex vectors, representing the “second” vertex of a triangle. For example, {i[m], j[m], k[m]} together represent face m (triangle m) in the mesh, where j[m] = n points to the triplet {x[n], y[n], z[n]} in the vertex arrays. Therefore, each element in j represents a point in space, which is the second vertex of a triangle.

  • jsrc – Sets the source reference on Chart Studio Cloud for j .

  • k – A vector of vertex indices, i.e. integer values between 0 and the length of the vertex vectors, representing the “third” vertex of a triangle. For example, {i[m], j[m], k[m]} together represent face m (triangle m) in the mesh, where k[m] = n points to the triplet {x[n], y[n], z[n]} in the vertex arrays. Therefore, each element in k represents a point in space, which is the third vertex of a triangle.

  • ksrc – Sets the source reference on Chart Studio Cloud for k .

  • 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.

  • lightingplotly.graph_objects.mesh3d.Lighting instance or dict with compatible properties

  • lightpositionplotly.graph_objects.mesh3d.Lightposition 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.

  • opacity – Sets the opacity of the surface. Please note that in the case of using high opacity values for example a value greater than or equal to 0.5 on two surfaces (and 0.25 with four surfaces), an overlay of multiple transparent surfaces may not perfectly be sorted in depth by the webgl API. This behavior may be improved in the near future and is subject to change.

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

  • scene – Sets a reference between this trace’s 3D coordinate system and a 3D scene. If “scene” (the default value), the (x,y,z) coordinates refer to layout.scene. If “scene2”, the (x,y,z) coordinates refer to layout.scene2, and so on.

  • 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.

  • streamplotly.graph_objects.mesh3d.Stream instance or dict with compatible properties

  • text – Sets the text elements associated with the vertices. If trace hoverinfo contains a “text” flag and “hovertext” is not set, these elements will be seen in the hover labels.

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

  • 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.

  • vertexcolor – Sets the color of each vertex Overrides “color”. While Red, green and blue colors are in the range of 0 and 255; in the case of having vertex color data in RGBA format, the alpha color should be normalized to be between 0 and 1.

  • vertexcolorsrc – Sets the source reference on Chart Studio Cloud for vertexcolor .

  • 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).

  • x – Sets the X coordinates of the vertices. The nth element of vectors x, y and z jointly represent the X, Y and Z coordinates of the nth vertex.

  • xcalendar – Sets the calendar system to use with x date data.
