Construct a new Histogram2dContour object

The sample data from which statistics are computed is set in x and y (where x and y represent marginal distributions, binning is set in xbins and ybins in this case) or z (where z represent the 2D distribution and binning set, binning is set by x and y in this case). The resulting distribution is visualized as a contour plot.

Parameters
  • arg – dict of properties compatible with this constructor or an instance of plotly.graph_objects.Histogram2dContour

  • autobinx – Obsolete: since v1.42 each bin attribute is auto- determined separately and autobinx is not needed. However, we accept autobinx: true or false and will update xbins accordingly before deleting autobinx from the trace.

  • autobiny – Obsolete: since v1.42 each bin attribute is auto- determined separately and autobiny is not needed. However, we accept autobiny: true or false and will update ybins accordingly before deleting autobiny from the trace.

  • 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.

  • bingroup – Set the xbingroup and ybingroup default prefix For example, setting a bingroup of 1 on two histogram2d traces will make them their x-bins and y-bins match separately.

  • 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.histogram2dcontour.ColorBa r 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.

  • contoursplotly.graph_objects.histogram2dcontour.Contour s instance or dict with compatible properties

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

  • histfunc – Specifies the binning function used for this histogram trace. If “count”, the histogram values are computed by counting the number of values lying inside each bin. If “sum”, “avg”, “min”, “max”, the histogram values are computed using the sum, the average, the minimum or the maximum of the values lying inside each bin respectively.

  • histnorm – Specifies the type of normalization used for this histogram trace. If “”, the span of each bar corresponds to the number of occurrences (i.e. the number of data points lying inside the bins). If “percent” / “probability”, the span of each bar corresponds to the percentage / fraction of occurrences with respect to the total number of sample points (here, the sum of all bin HEIGHTS equals 100% / 1). If “density”, the span of each bar corresponds to the number of occurrences in a bin divided by the size of the bin interval (here, the sum of all bin AREAS equals the total number of sample points). If probability density, the area of each bar corresponds to the probability that an event will fall into the corresponding bin (here, the sum of all bin AREAS equals 1).

  • 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.histogram2dcontour.Hoverla bel 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/d3-3.x-api- reference/blob/master/Time-Formatting.md#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. variable z 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 .

  • 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 .

  • 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.

  • nbinsx – Specifies the maximum number of desired bins. This value will be used in an algorithm that will decide the optimal bin size such that the histogram best visualizes the distribution of the data. Ignored if xbins.size is provided.

  • nbinsy – Specifies the maximum number of desired bins. This value will be used in an algorithm that will decide the optimal bin size such that the histogram best visualizes the distribution of the data. Ignored if ybins.size is provided.

  • 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.

  • 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).

  • x – Sets the sample data to be binned on the x axis.

  • ycalendar – Sets the calendar system to use with y date data.

  • ysrc – Sets the source reference on Chart Studio Cloud for y .

  • z – Sets the aggregation data.

  • 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.

  • zhoverformat – Sets the hover text formatting rule using d3 formatting mini-languages which are very similar to those in Python. See: https://github.com/d3/d3-3.x-api- reference/blob/master/Formatting.md#d3_format

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”

Sets the maximum number of points to keep on the plots from an incoming stream. If maxpoints is set to 50, only the newest 50 points will be displayed on the plot.

The ‘maxpoints’ property is a number and may be specified as:
  • An int or float in the interval [0, 10000]

Returns

Return type

int|float

property token

The stream id number links a data trace on a plot with a stream. See https://chart-studio.plotly.com/settings for more details.

The ‘token’ property is a string and must be specified as:
  • A non-empty string

Returns

Return type

str

class plotly.graph_objects.histogram2dcontour.XBins(arg=None, end=None, size=None, start=None, **kwargs)
property end

Sets the end value for the x axis bins. The last bin may not end exactly at this value, we increment the bin edge by size from start until we reach or exceed end. Defaults to the maximum data value. Like start, for dates use a date string, and for category data end is based on the category serial numbers.

The ‘end’ property accepts values of any type

Returns

Return type

Any

property size

If nbinsx is 0 or omitted, we choose a nice round bin size such that the number of bins is about the same as the typical number of samples in each bin. If nbinsx is provided, we choose a nice round bin size giving no more than that many bins. For date data, use milliseconds or “M<n>” for months, as in axis.dtick. For category data, the number of categories to bin together (always defaults to 1).

The ‘size’ property accepts values of any type

Returns

Return type

Any

Type

Sets the size of each x axis bin. Default behavior

property start

Sets the starting value for the x axis bins. Defaults to the minimum data value, shifted down if necessary to make nice round values and to remove ambiguous bin edges. For example, if most of the data is integers we shift the bin edges 0.5 down, so a size of 5 would have a default start of -0.5, so it is clear that 0-4 are in the first bin, 5-9 in the second, but continuous data gets a start of 0 and bins [0,5), [5,10) etc. Dates behave similarly, and start should be a date string. For category data, start is based on the category serial numbers, and defaults to -0.5.

class plotly.graph_objects.histogram2dcontour.YBins(arg=None, end=None, size=None, start=None, **kwargs)
property end

Sets the end value for the y axis bins. The last bin may not end exactly at this value, we increment the bin edge by size from start until we reach or exceed end. Defaults to the maximum data value. Like start, for dates use a date string, and for category data end is based on the category serial numbers.

The ‘end’ property accepts values of any type

Returns

Return type
