Good day.

Is it possible to set the color of annotation text?

Example:
When using a statement similar to:

this.AddAnnotation(SPCChartObjects.PRIMARY_CHART, 23, "XY");

can the foreground and/or the background color of XY be controlled?

If so, is it a global setting or can the attributes of each annotation be set individually?

Thank you.

You can set the color of the annotation (each can be different) by adding this method to your chart defining class:

void AddAnnotation(int chart, int dataindex, String text, Color c)
{
int textindex = AddAnnotation(chart, dataindex, text);
SPCChartObjects chartobj = (chart == SPCChartObjects.PRIMARY_CHART ? PrimaryChart : SecondaryChart);
ChartText textobj = (ChartText)chartobj.AnnotationArray[textindex];
textobj.SetColor(c);

}

It calls the base class AddAnnotaion, and then sets the color of the resulting ChartText object to your specified color.
