I add a single null value with AddNullXY to a LineSeries and the Point is visible! The points are correct invisible if I add a second null value.
Is it possilbe to get a bugfix for this?

Hi Bert,
Thanks for reporting. I could reproduce the issue here. This happens with line series with visible pointers and with point series as well. I've added the defect (TV52011780) to our bug list to be fixed for future releases.
In the meantime, a workaround is using the following code in the series OnGetPointerStyle event.
Code: Select all
function TForm1.Series1GetPointerStyle(Sender: TChartSeries;
ValueIndex: Integer): TSeriesPointerStyle;
begin
if ((Sender.Count=1) and (ValueIndex=0) and
(Sender.ValueColor[ValueIndex]=clNone)) then
result:=psNothing
else
result:=psRectangle;
end;
Another solution is only using an empty OnGetPointerStyle event:
Code: Select all
function TForm1.Series1GetPointerStyle(Sender: TChartSeries;
ValueIndex: Integer): TSeriesPointerStyle;
begin
//
end;
