class CategoricalHistogram(PlotlyViewPlot): (source)

A histogram of a categorial field.

Parameters
field_or_expr	a field name, `embedded.field.name`, `fiftyone.core.expressions.ViewExpression`, or MongoDB expression defining the field or expression to plot
expr	an optional `fiftyone.core.expressions.ViewExpression` or MongoDB expression to apply to `field_or_expr` (which must be a field) before plotting
order	the x-axis ordering strategy to use. Can be "alphabetical" to sort by field value, or "frequency" to sort in descending order of frequency, or a function suitable for `sorted(items, key=order)`, where `items` is a list of `(value, count)` tuples
xlabel	an optional x-label for the plot
log	whether to use a log scale y-axis
bargap	relative spacing between bars in `[0, 1]`
color	a color for the bars. Can be any color supported by `plotly:plotly.graph_objects.bar.Marker.color`
opacity	an optional opacity for the bars in `[0, 1]`
init_view	an optional initial `fiftyone.core.collections.SampleCollection` to load
**kwargs	optional parameters for `plotly:plotly.graph_objects.Figure.update_layout`
