How do I programmatically change from small dots to circles in a TChart ? Is it possible to have circles which are colored individually as they are drawn like small dots ?

HI,
I have a TChart and am using AddXY to plot individual points. For example, Chart1.Series[0].AddXY(X,Y, ' ', clBlue0);
I am using small dots because they look good and can be individually colored with the AddXY command. However, when zoomed in quite a bit they become almost impossible to see. You can see examples of this if you look at my other open question to which I have stopped getting responses. If I could programmatically switch from small dots to circles when needed, it would make it easy to see the plotted lines even when zoomed in too much. Can someone show me the command that would change the small dots to circles ? Is it possible to make circles in different colors as it is woth small dots ?

Never mind. I found the answers myself. The circles were not colored because of the border. It was set to black and so a line of closely spaced circles looked black until I made the border invisible. I found the commands to change from small dots to circles: Series1.Pointer.Style := paCircle; Of course Series1.Pointer.Style := paSmallDot; changes it back. To change the size of the circles: Series1.Pointer.Size := CircleSize; CircleSize is an integer.
