[Lazarus] TAChart

[Werner Pamler]

Oh - the old "uses" issue... "psCircle" is declared in unit TATypes 
which is not added to "uses" automatically at runtime.

At designtime, just use the ObjectInspector: The tree above the Object 
Inspector shows the chart and the series as a child of the chart. Click 
on the series to brings the series properties into the Object Inspector. 
Scroll down a bit to see the "Pointer" property, open the node and find 
the "Style".

Maybe you are interested also in my forum posting of today containing a 
lot of TAChart runtime code:
