how to use CategoryTextAnnotation

Hi,

I just upgraded my jfreechart from 0.96 to 0.98 and tried to use the new feature of "CategoryTextAnnotation". But it seemed not working working. Does anybody have any example of this? What does the parameter "java.lang.Comparable category" and "double value" mean? How do i use it?

Thanks in advance!
Yu

These specify where the text will be placed on the chart. The category refers to the position on the domain axis, and the value refers to the position on the range axis.

plot.addRangeMarker(marker); // drawing average
CategoryTextAnnotation categoryTextAnnotation1 = new CategoryTextAnnotation("Average ",new Font("SansSerif", Font.PLAIN, 20), Color.red, "",marker.getValue());
plot.addAnnotation(categoryTextAnnotation1);
