Degraded performance upgrading to TeeChart For VS 2005

Post by nico193 » Thu Jun 18, 2009 1:19 pm

Hello,

We're using Teechart V 1.1.1544.23908 for VS 2003 since 4 years in a .NET application.

We're now trying to upgrade to VS 2005 and would like to have the latest Steema Teechart version (V4.0).

Letting the code as is and migrate to VS 2005 + Steema Teechart V4.0, we're facing some importantg performance problems :

- When simply adding points to series (millions of points)
- When using the cursor tools (some lags are appearing when handling the cursor tools)

Are there some code modifications to be done to optimize performance ?

Thanks for advice.

Hello nico193,
Are there some code modifications to be done to optimize performance ?
In the article real time charting that you find here there are some advice methods which will improve plotting speed, but not all methods are applicables in .NET, because there are methods only used and impplemented in vcl version. Also, you can see demos specifically Speed All Features\Welcome !\Speed\Realtime charting , All Features\Welcome !\Speed\Fast Line Speed DrawAll or Cursor All Features\Welcome !\Tools\Cursor\Cursor Scope, using the propierty FastCursor.

If you still have problems with application, you could send us a simple example project we can run "as-is" to reproduce the problem here?
You can either post your files at news://www.steema.net/steema.public.attachments newsgroup or at ourupload page. Now you can ulpoad attacment directly in the post.

Thanks,
