Matrix Chart#

Plots a “matrix” chart. This can be a heat map, or a matrix of pie or petal plots:

The default behavior will produce a “traditional” heat map, where each “cell” is a circle and the color of the circle is related to the intensity of the value of Feature. (In this scenario, Variable must be left empty.)

Setting Style to Pie plot will draw a pie plot in each cell. The values of Variable are used as the categories of the pie, and the arc length of each slice of pie is related to the intensity of the value of Feature.

Setting Style to Petal plot will draw a “petal plot” in each cell. The values of Variable are used as the categories, but unlike a pie plot, the arc width of each slice is equal. Instead, the radius of the pie slice scales with the square root of the intensity, so that the relationship between area and intensity remains the same.

Optionally, you can set Scale by events to scale the total size of each circle, pie or petal plot by the number of events that match the category.

Statistic: Which statistic to plot. This is usually the name of the operation that added the statistic.

Horizontal Facet: What statistic variable should be plotted in the columns of the matrix plot? If left unset, there will only be one column.

Vertical Facet: What statistic variable should be plotted in the rows of the matrix plot? If left unset, there will only be one row.

Feature: Which column in the statistic should be plotted?

Variable: The statistic variable to classify segments in pie or petal plots.

Style: Which style matrix view to plot?

Scale: How to scale the color, arc length or radii of the plots.

Subset: Plot only a subset of the statistic.

Scale by Events: If set, scale each circle/pie/petal by the number of matching events.
