Dear Support

I have a very simple question: is there a limit how many line (or point, or both) series I can put on a chart?

Tx, regards

Something to bear in mind...

If this is a real time graph and you are not using FastLineSeries it will be very slow to plot a graph with this many items.

My application generates around 20 items per second, with a new series every 20 seconds When using LineSeries, I couldn't show 1000 series of 100 items in real time.

The way I overcame this was when there are more than 100 series, remove every other series. In this way the display only has to show a maximum of 100*100*25 points.

YMMV

Hi,

you can find a good technical article about the Real-Time charting here.

It's for VCL version but could be applicable in the ActiveX version.
