When drawing points on a line graph, is it possible, via code, to make the
points round and without a black boarder?
Could someone give me any code examples please?

You need to initialize the YCount of the chart source. Just call

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

Hi!
At r50753 "wp" created the support for localization of TAChart, but it

Most of these files contains only 1 (one) sentence (four is the most).
I think there is no reason for this fragmentation, especially because
