Struct Histogram2D

Source

pub struct Histogram2D<'a> { /* private fields */ }

Expand description

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 heatmap.

Implementations§

Source §

impl<'a> Histogram2D<'a>

Source

pub fn visible(&mut self, visible: Visible) -> &mut Self

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).

default: true

Source

pub fn legendgroup(&mut self, legendgroup: &'a str) -> &mut Self

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

default: ``

Source

pub fn opacity(&mut self, opacity: f64) -> &mut Self

Sets the opacity of the trace.

default: 1

Source

pub fn name(&mut self, name: &'a str) -> &mut Self

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

Source

pub fn uid(&mut self, uid: &'a str) -> &mut Self

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

Source

pub fn ids(&mut self, ids: &'a [&'a str]) -> &mut Self

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.

Source

pub fn meta(&mut self, meta: Any) -> &mut Self

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.

Source

pub fn hoverinfo(&mut self) -> &mut 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.

default: all

Source

pub fn hoverlabel(&mut self) -> &mut Hoverlabel<'a>

Source

pub fn stream(&mut self) -> &mut Stream<'a>

Source

pub fn uirevision(&mut self, uirevision: Any) -> &mut Self

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.

Source

pub fn x(&mut self, x: &'a [f64]) -> &mut Self

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

Source

pub fn y(&mut self, y: &'a [f64]) -> &mut Self

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

Source

pub fn z(&mut self, z: &'a [f64]) -> &mut Self

Sets the aggregation data.

Source

pub fn marker(&mut self) -> &mut Marker<'a>

Source

pub fn histnorm(&mut self, histnorm: Histnorm) -> &mut Self

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).

default: ``

Source

pub fn histfunc(&mut self, histfunc: Histfunc) -> &mut Self

default: count

Source

Source

pub fn xbins(&mut self) -> &mut Xbins

Source

pub fn nbinsy(&mut self, nbinsy: u64) -> &mut Self

pub fn ybins(&mut self) -> &mut Ybins

Source

pub fn autobinx(&mut self, autobinx: bool) -> &mut Self

Source

pub fn autobiny(&mut self, autobiny: bool) -> &mut Self

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.

default: null
