Construct a new Histogram object

The sample data from which statistics are computed is set in x for vertically spanning histograms and in y for horizontally spanning histograms. Binning options are set xbins and ybins respectively if no aggregation data is provided.

Parameters

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

  • alignmentgroup – 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.

  • 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.

  • bingroup – Set a group of histogram traces which will have compatible bin settings. Note that traces on the same subplot and with the same “orientation” under barmode “stack”, “relative” and “group” are forced into the same bingroup, Using bingroup, traces under barmode “overlay” and on different axes (of the same axis type) can have compatible bin settings. Note that histogram and histogram2d* trace can share the same bingroup

  • cliponaxis – Determines whether the text nodes are clipped about the subplot axes. To show the text nodes above axis lines and tick labels, make sure to set xaxis.layer and yaxis.layer to below traces.

  • constraintext – Constrain the size of text inside or outside a bar to be no larger than the bar itself.

  • cumulative – plotly.graph_objects.histogram.Cumulative 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.

  • error_x – plotly.graph_objects.histogram.ErrorX instance or dict with compatible properties

  • error_y – plotly.graph_objects.histogram.ErrorY instance or dict with compatible properties

  • 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.

  • hoverlabel – plotly.graph_objects.histogram.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. Finally, the template string has access to variable binNumber 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>.

  • legendgrouptitle – :class:`plotly.graph_objects.histogram.Legendgrouptitle ` 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.

  • marker – plotly.graph_objects.histogram.Marker 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 appears as the legend item and on hover.

  • outsidetextfont – Sets the font used for text lying outside the bar.

  • selected – plotly.graph_objects.histogram.Selected instance or dict with compatible properties

  • selectedpoints – Array containing integer indices of selected points. Has an effect only for traces that support selections.

  • textfont – Sets the text font.

  • textposition – Specifies the location of the text. “inside” positions text inside, next to the bar end (rotated and scaled if needed). “outside” positions text outside, next to the bar end (scaled if needed), unless there is another bar stacked on this one, then the text gets pushed inside. “auto” tries to position text inside the bar, but if the bar is too small and no bar is stacked on this one the text is moved outside. If “none”, no text appears.

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

  • texttemplate – Template string used for rendering the information text that appear on points. Note that this will override textinfo. 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-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. Finally, the template string has access to variables label and value.

  • 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.

  • unselected – plotly.graph_objects.histogram.Unselected instance or dict with compatible properties

  • 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.

  • xaxis – 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.

  • xbins – plotly.graph_objects.histogram.XBins instance or dict with compatible properties

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

  • xhoverformat – 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 *09~15~23.46*By default the values are formatted using xaxis.hoverformat.

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

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

  • 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.

  • ybins – plotly.graph_objects.histogram.YBins instance or dict with compatible properties

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

  • yhoverformat – 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.

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

  • zorder – 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.

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). If multiple non-overlaying histograms share a subplot, the first explicit size is used and all others discarded.
