Exporting WPF TChart to XAML. Clipped rectangle borders.

[neurosoft]

Hello steema!
I've downloaded the latest version of WPF TeeChart. And I've got some new bugs in exporting TeeChart to XAML.
If I try to export Bar with borders or Point with borders and pointer style as Rectangle, I have incorrect result. Clip rectangles are too small for that series.
For example, try to execute the following code:

Code: Select all

       
            MyTChart.Aspect.View3D = false;
            Points points = new Points();
            points.Pointer.Style = PointerStyles.Rectangle;
            points.Pointer.Pen.Color = Colors.Black;            
            points.Add(10);
            MyTChart.Series.Add(points);

            Bar bar = new Bar();
            bar.Add(5);
            bar.Pen.Color = Colors.Black;
            bar.Brush.Color = Colors.White;                    
            MyTChart.Series.Add(bar);

and then

Code: Select all

MyTChart.Export.Image.XAML.Save(exportedXamlPath);

You will see, that some borders in source TeeChart are clipped in exported XAML.

If you open exported XAML with text editor, you can see incorrect part:

<Rectangle Fill="#FFFFFFFF" StrokeThickness="1" Stroke="#FF000000"
Canvas.Left="115.176666666667" Canvas.Top="63" Width="10" Height="10">
<Rectangle.Clip>
<RectangleGeometry Rect="0,0,9,9"/>
</Rectangle.Clip>
</Rectangle>
<Rectangle Fill="#FFFFFFFF" StrokeThickness="1" Stroke="#FF000000"
Canvas.Left="89.1766666666667" Canvas.Top="119" Width="62" Height="53">
<Rectangle.Clip>
<RectangleGeometry Rect="0,0,61,52"/>
</Rectangle.Clip>
</Rectangle>

I have the same problem with FastLine series.
Every line in exported TeeChart is clipped by rectangle. I don't know why do you do it, but it's not good.
You can see it by exporting the TeeChart with the next fast line, for example:

Code: Select all

                FastLine fastLine = new FastLine();
                fastLine.ShowInLegend = false;
               
                for (int i = 0; i < 50; i++)
                {
                    double x = i / 5d;
                    fastLine.Add(x, Math.Sin(x) * 3);
                }
                MyTChart.Series.Add(fastLine);

The source TeeChart is:

The exported XAML looks like this:

Maybe I'm mistaken, but I think you have to clip once all TeeChart region, not every object, placed on the TeeChart.

Hello neurosoft,

Thanks for information. I have added the problem in the bug list report with number[TF02016503]. We will try to fix it for next maintenance releases.

Thanks,

Hello neurosoft,

I inform you that we have already fixed the bug number[TF02016503] to next version of TeeChartFor.Net. On the other hand, we have made for you a simple workaround that solve the problem that occurs because of a discrepancy between Rectangle.Clip and Width and Height. It consist in modify the xaml file manually to correct the error.

Code: Select all

  <Rectangle Fill="#FFFFFFFF" StrokeThickness="1" Stroke="Black"

Canvas.Left="261" Canvas.Top="72" Width="10" Height="10">

    <Rectangle.Clip>

      <RectangleGeometry Rect="0,0,9,9"/>

    </Rectangle.Clip>

  </Rectangle>

As you see in previous code, changing the Width and Height from “10” to “9” fixes the problem.

Thanks,

Hello steema,
I'm very disapointed because my problem is not fixed in the latest release. I've downloaded WPF TeeChart ver. 4.1.2013.05282. The problem TF02016503 is marked as fixed in "Release Notes", but everything which I wrote above is true.
I have no words to describe what I think about it.

Hello neurosft,

Ok. After doing some tests using Winforms and Wpf we get next results:

Winforms vs WPF Bar export:
If we export the Bar as a xaml when you we use winforms the problem is solved.
If we export the Bar as a xaml when we use wpf MainForm the problem persist.
Conclusion, in the case of Bar, seems the problem isn't solved by wpf but is solved in Winforms, for this reason we close the bug. Therefore, we have added again it in bug list report with number [TF02016608].

Winforms vs WPF FastLine export:
The problems isn't solved for the both cases. We have added a new bug report with number [TW16016609]. We will try to fix it to upcoming versions of TeeChartFor.Net.

We apologize with you for consider a bug fixed when it isn't completely, I have made a mistake to think the bug is fixed, checking only the behavior of exporting for Bar series in Winforms.

Thanks and sorry,
