GetNumColors: Determines the number of colors required in a chart

In Displayr/flipChartBasics: Pre-processing functions used for plotting

Determines the number of colors required in a chart

Description

Returns the number of colors needed in a chart. This is returned as a list because more than one color-series may be required (e.g. Pie chart)

Usage

GetNumColors(
  data,
  chart.type,
  scatter.colors.column = 4,
  multi.color.series = FALSE
)

Arguments

data	Input data, a named vector or matrix.
chart.type	Type of chart to plot
scatter.colors.column	For scatterplot data, the column of data which is used to determine the colors of each point.
multi.color.series	For bar and column charts, a logical indicating how colors are used. By default, this value is set to FALSE, in which case the number of colors returned is equal to the number of data series (or columns) in data. When multi.color.series == TRUE, multiple colors are assigned to the categories within a single data series, so the number of colors returned is equal to NROW(data).

Value

An integer specifying the number of colors used by the chart.
