dear specialists

i have list of datapoints which want to present as single-points
(preferably with the option to use different shapes of the points).

this is basic item in charts so I wondered why this is not on the
series list ;
so i must have missed this important "point".

so how do handle pointseries in TAchart"?

The TLineSeries is what you need: To show the points set its
"ShowPoints" to "True", and to hide the connecting lines, set its
"LineType" to "ltNone". Note that the "SeriesColor" applies only to
the connecting lines; to specify the color of the points change the
"Pointer.Brush.Color" for the fill and/or "Pointer.Pen.Color" for the
border line color. The "Pointer" property also gives access to the
"Style" (circle, triangle, box, etc).
