I want to use Pointer in FastLine series, but i don't find this property in it. I only see it on Line series, but i don't want Line series, because my data is very large about 1 million point. Teechart re-draw very slow with this data when i resize or repaint it. So i want to use FastLine to improve it.
You has other way to improve performance, hasn't you? Please help me.

Hi Tuan Nguyen,

FastLine series don't support Pointers. If you want to use them you'll have to use Line series. At this article you'll find some hints on how to improve TeeChart's performance. Even it's a Delphi written article the same applies to TeeChart Pro ActiveX.

On this article, It only show me use FastLine series to improve performance. So i won't improve performance if i use Line series. You has some other hints for me, hasn't you?

Hi Tuan,

It's true that it uses FastLine series as it is the fastest performance series we have. However, some of the hints given in that article are transparent to the series you use or common to all series styles. So I'd recommend you to try to apply them to your application and check if improves its performance.

Thanks in advance.
