I did some informal testing using a stopwatch. I used the fillSampleValues() method to add some random values to a point series. In this testing, I found that when building a scatter chart with more than around 10,000 points, that the render time would be too slow. I would like to see the render time down around 5 seconds.
Is there anything I can do do plot a very large number of points faster?

Hi Jesse,
Yes, I strongly recommend you to read the Real-time Charting article here. It's a Delphi and TeeChart VCL article but most of it can also be applied to other TeeChart versions.
You'll also find some more suggestions in the All Features\Welcome!\Speed and All Features\Welcome!\Fast Line examples at TeeChart.Features.jar demo included in TeeChart's installation.
Hope this helps!

Hi Jesse,
There's nothing specific for Points series. In that case you could try applying as many of those hints as possible in Points series. Some of them are not even series related .
