grCategoryColor(CHART_Chart1, 3, LightRed)
grCategoryColor(<Chart name> , <Category number> , <Color>)
<Chart name>: Control name or character string
Name of the chart to be used. This name can correspond to:
  • the chart name defined through programming with grCreate.
  • the name of the Chart control in the window, page or report editor.
<Category number>: Integer
Number of the category to modify.
For a Pie chart (grPie constant), this parameter corresponds to the subscript of data in the series (the section number). In this case, this function is equivalent to grSeriesColor.
For a Column chart (grColumn constant), this parameter corresponds to the category subscript: all the bars of the category will be colored. The colors specified for the category series will be ignored.
For a Bubble chart (grBubbleChart constant), this parameter corresponds to the category subscript: the bubble corresponding to the category will be colored.
<Color>: Integer or Integer constant
Color of specified category. This color can correspond to:
  • The colors defined by grCategoryColor will be taken into account during the next call to grDraw.
  • To display the color gradients, use grGradient.
  • The colors specified by grCategoryColor are taken into account in the Waterfall charts. You also have the ability to define the colors of categories in the Waterfall charts with grWaterfallColor.
