Construct a new Densitymap object

Draws a bivariate kernel density estimation with a Gaussian kernel from lon and lat coordinates and optional z values using a colorscale.

Parameters

  • arg – dict of properties compatible with this constructor or an instance of plotly.graph_objects.Densitymap

  • 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.

  • below – Determines if the densitymap trace will be inserted before the layer with the specified ID. By default, densitymap traces are placed below the first layer of type symbol If set to ‘’, the layer will be inserted above every existing layer.

  • 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.densitymap.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: Blackbody,Bluered,Blues,C ividis,Earth,Electric,Greens,Greys,Hot,Jet,Picnic,Portl and,Rainbow,RdBu,Reds,Viridis,YlGnBu,YlOrRd.

  • 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.

  • 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.densitymap.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}” 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. 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 – Sets hover text elements associated with each (lon,lat) pair If a single string, the same string appears over all the data points. If an array of string, the items are mapped in order to the this trace’s (lon,lat) coordinates. To be seen, trace hoverinfo must contain a “text” flag.

  • 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.

  • lat – Sets the latitude coordinates (in degrees North).

  • latsrc – Sets the source reference on Chart Studio Cloud for lat.

  • legend – Sets the reference to a legend to show this trace in. References to these legends are “legend”, “legend2”, “legend3”, etc. Settings for these legends are set in the layout, under layout.legend, layout.legend2, etc.

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

  • legendgrouptitle – plotly.graph_objects.densitymap.Legendgrouptitl e instance or dict with compatible properties

  • legendrank – 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. When having unranked or equal rank items shapes would be displayed after traces i.e. according to their order in data and layout.

  • legendwidth – Sets the width (in px or fraction) of the legend for this trace.

  • lon – Sets the longitude coordinates (in degrees East).

  • lonsrc – Sets the source reference on Chart Studio Cloud for lon.

  • 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 appears as the legend item and on hover.

  • opacity – Sets the opacity of the trace.

  • radius – Sets the radius of influence of one lon / lat point in pixels. Increasing the value makes the densitymap trace smoother, but less detailed.

  • radiussrc – Sets the source reference on Chart Studio Cloud for radius.

  • 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.densitymap.Stream instance or dict with compatible properties

  • subplot – Sets a reference between this trace’s data coordinates and a map subplot. If “map” (the default value), the data refer to layout.map. If “map2”, the data refer to layout.map2, and so on.

  • text – Sets text elements associated with each (lon,lat) pair If a single string, the same string appears over all the data points. If an array of string, the items are mapped in order to the this trace’s (lon,lat) coordinates. 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.

  • 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).

  • z – Sets the points’ weight. For example, a value of 10 would be equivalent to having 10 points of weight 1 in the same spot

  • zauto – Determines whether or not the color domain is computed with respect to the input data (here in z) or the bounds set in zmin and zmax Defaults to false when zmin and zmax are set by the user.

  • zmax – Sets the upper bound of the color domain. Value should have the same units as in z and if set, zmin must be set as well.

  • zmid – Sets the mid-point of the color domain by scaling zmin and/or zmax to be equidistant to this point. Value should have the same units as in z. Has no effect when zauto is false.

  • zmin – Sets the lower bound of the color domain. Value should have the same units as in z and if set, zmax must be set as well.

  • zsrc – Sets the source reference on Chart Studio Cloud for z.

property dtick

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 axis type 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<f>”, where f is a positive number, gives ticks linearly spaced in value (but not position). For example tick0 = 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 axis type is “date”, then you must convert the time to milliseconds. For example, to set the interval between ticks to one day, set dtick to 86400000.0. “date” also has special values “M<n>” gives ticks spaced by a number of months. n must be a positive integer. To set ticks on the 15th of every third month, set tick0 to “2000-01-15” and dtick to “M3”. To set ticks every 4 years, set dtick to “M48”
