Performance problems with much series

[CTgmbh]

Hi,
we got charts with much series. When we scroll or zoom the chart everything is very slow. I tried to use another canvas like GDI and GDI+. It can't be the machine. I try it on a new notebook that's less then four months old (2.6GHz Core 2 Duo, 4GB Ram, ATI Radeon 3650 512MB). This doesn't help. Do you know any tricks to get better performance with a lot of series/data?

TeeChart 7.08 on BDS2006 (Delphi)

I've attached a tee file with much series and data. It looks very overloaded but that's correct (it's a non filtered selection of data).

Hi Tom

It would be more helpful a tee file saved as text to allow us to see how was it exactly set:

Code: Select all

SaveChartToFile(Chart1,'c:\tmp\performance.tee',True);

On the other hand, could you please tell us what exactly TeeChart version are you using?

Anyway, please, take a look at the Real-time Charting article. There are some tips you could use to improve your chart performance.

I will do that.


I just took a look at the documentation. I was looking if I can use TFastLineSeries instead of TLineSeries but I can't

Oups, Excuse me.

I'm not sure to understand why you can't use Fast Lines instead of Lines. Your lines don't have pointers visible, your chart isn't in 3D,...
