NET 2 & NET 3 versions of TChart - differences

[Narcís]

Hi speedwell,

Ok, I'll add this to the bug list to be reviewed as well.

Hi speedwell,

For completeness, possibly you needed to use Clear method before populating series, didn't you?

Code: Select all

			shape1.Clear();
			shape1.Add(-50, -50);
			shape1.Add(50, 50); 

Thanks in advance.

My word...slow day in Spain?

As you will see from my original code snippet the shape has just been created.
Are you indicating that by default X Y are now automatically populated with (0, 0) (100, 100) on shape creation - hence the need to call Clear()?

I've seen you didn't use the Clear call in the code you posted but I compared this behaviour with other TeeChart versions and found that it was necessary there.

Yes, exactly. Anyway, I'll document the differences in TeeChart versions as well so that it's easier for us to track down when those changes occured.

Please notice that first TeeChart version was the VCL version. From it a COM wrapper was created for the ActiveX version and later on it was ported to the .NET environment for creating TeeChart for .NET.

I've uploaded a jpg which can be loaded into a ColorGrid using code such as:

Code: Select all

bitMap = new Bitmap("Lock_Up_ColorGrid.jpg");
colorGrid.Bitmap = bitMap;

In the latest TChart v3.5.3065.19161 and earlier versions TChart hangs on the Bitmap assignment. This works OK on my "reference" v2.0.2586.24039

The Shape Global Pen Color property no longer works (v3.5.3065.19161). This can be seen in your "Feature Demo" project by Looking at the "Map GIS" demo, clicking "Edit", then attempting to modify the Border color.

Notice that if you change the "Width", the chart resizes to accomodate the extra pen width, but the colour nor the new line width (nor style changes) are rendered.

I notice that setting up the above global shape properties via code works OK until the chart is resized where the the shape border color is lost.

I could reproduce the issue here and added it (TF02013086) to our bug list to be fixed for next releases.

Thanks for reporting. I could reproduce this issue here and added it to the defect list (TF02013087) to be fixed.

Hi speedwell,

Please notice that I splitted this topic so that a new thread is created for each issue, this makes easier to follow the issues and topics more coherent. New topic can be found here:
