ColorGrid, high number points and zoom...

cfalcot · Post by **cfalcot** » Wed Mar 02, 2005 12:36 pm

Hello,

I'm playing again with high number points ColorGridSeries... I am very confused with the max number of points. I work on an old soft I did with TeeChart5(Demo) and Delphi 6. After doing compatibility correction for TeeChart6 and Delphi7 it works good BUT…
On one ColorGridSeries I can draw perfectly more than 2000*20 points. On the other one I have problems: if I edit the series with the editor, values aren’t affected. If I load less than 2000 points, all is right with the 2 charts.

So my question is why in one chart I can work on series with more than 2000 points without problems and why in other same type graph I can’t do it? (I read remarks about limit number of 2000*2000 points)

Another problem is that when I zoom on a ColorGrid Chart, sometimes nothing is drown. What is the problem with that?

Thanks

Cyril

Hi Cyril,

So my question is why in one chart I can work on series with more than 2000 points without problems and why in other same type graph I can’t do it? (I read remarks about limit number of 2000*2000 points)

Until the TeeChart Pro v5 the limit was 2000 x 2000, since the TeeChart Pro v6, this limit has been removed, from the new features doc :

"Removed grid size limit in all 3D series (was 2000 x 2000).
Internal xyz grid data is stored into dynamically growing arrays, with no limit on size."

Another problem is that when I zoom on a ColorGrid Chart, sometimes nothing is drown. What is the problem with that?

It's hard to tell you without being able to reproduce it here, could you please tell us the steps to reproduce it ?

Earlier versions of TChart did show a blank chart after being highly zoomed. But the latest vesions (7.0X ?) do not exhibit this behavior and can be zoomed I think down to 1 x 1 data points.

Hi,

I think that problem in my projects appeared when I upgrade TeeChart V5 with TeeChart V6.

Problems with zoom are solved by delete and recreate new chart. Problem with space limitation seems to be solved too.

But this method can’t solve another problem with ChartEditor: I have not the Format menu with a ColorGridSeries in execution mode (.exe). However the menu appears when I double click on the chart in the Delphi project. I try to delete all ChartEditor, save the project, close it, open it and recreate ChartEditor but this don’t work… The most strange is that this menu appears in software I create with TeeChart V6 (and not V5 with upgrade to V6)…

I hope I am clear. Thank’s for your ideas…

Cyril

Hi Cyril,

That's very strange. Could you please send us a project reproducing this problem we can run "as-is" at [url]news://www.steema.net/steema.public.attachments[/url] newsgroup?

Thanks in advance.

Hi,

I don't know the way to use the link you give to me in Outlook. Could you help me to post you my ZIP file with the project?

Thanks

Hi Cyril,

Of course, you just have to configure www.steema.net as a news account server in your newsreader (i.e.: Outlook Express, MS Office Outlook doesn't support newsreading). The configuration parameteres for www.steema.net are the default ones.

Something easier for you may be typing and runing the "news://www.steema.net/steema.public.attachments" command at start menu>run entry. This will automatically open this account in Outlook Express or your default newsreader.

Hi,

I can't give you my project because my article is too large. If you want I can put it on my FTP serveur and create an account for you.

Regard's
Cyril

Hi Cyril,

Wouldn't it be easier if you sent it directly to me?
