Specifies what color the chart uses for its appearance. Depending on the chart type, the Color property will change the color of the Brush or of the Pen that the chart draws with.
For example, for a TRSAreaChart, the Color property changes the Brush color, which is used to fill the areas in the chart. For the TRSLineChart, the Color property changes the Pen Color, which is used to draw the lines in the chart. Note that if coColorEachPoint is in the Options property, the chart will use each individual TRSChartValue's Color property instead.
