Hi,
I currently have an issue with plotting a XY chart.
I have 2 data X and Y which are functions of time: X=X(t) and Y=Y(t). I intend to plot Y versus X over N samples and update the curve periodically.
Currently the code is as follows:

with Series1 do begin
for i:= 0 to N-1 do begin
AddXY(X(t),Y(t),'');
if count>N then delete(0);
end;
end;

The code above works. But recently I have got an measuring instrument which outputs data at high rate. If I update the curve very quickly, a runtime error occurs after few minutes.

Could you advise about the reason of this runtime error ? How I could do to make a more efficient code ?

Thanks

Hello Sciensoria,

Would be very grateful if you can arrange for us a "Minimal, Complete, and Verifiable example (MCVE)" as specified in the here because we can reproduce your problem exactly here. Is possible you do that?

Thanks in advance for your help
