Releases 6, 12 Feb 2009 incompatible with previous releases.

[georgez]

The 6 Feb 2009 release (build 3324) claims fixes to zooming and scrolling. When we use 3324 with new charts zooming works OK. When we use 3324 with .ten files stored in a database using previous releases (for example, 3146) we get a NEW variety of bad effects.
1. In some cases, zooming on any part of the series near the left end results in the series going invisible, although the grid itself zooms. In the same cases zooming near the right end works OK.
2. In other cases your CalcFirstLastVisibleIndex throws an IndexOutOfRangeException.

Hi georgez,

Could you please send us examples *.ten files or even better a simple example project we can run "as-is" to reproduce the problem here? It would be very helpful if we could see how such charts are created exactly.

You can either post your files at news://www.steema.net/steema.public.attachments newsgroup or at our upload page.

Thanks in advance.

Hi Narcís,

Unfortunately we will be unable to generate external data. The online charts are sent to a stream with Export.Template.Save, and the stream is stored as BinaryData in a database 'image' field. To get it back online we do the reverse with Import.Template.Load. However, since the project philosophy is to store ALL work in the database, there is purposely no facility to generate external files from either the online charts or the database.

Hi georgez,

It would also help if you could arrange a simple example project which produces a *.ten file which produces such errors when loaded with newer TeeChart for .NET v3 releases.

Thanks in advance.

Narcis,

We posted a chart to your upload page. With the new VCL version, zooming on the cluster at the left side exhibits the disappearing series effect.

Hi georgez,

I've tested and reproduced the problem with your ten file. Now, I'm trying to create a chart similar to yours to identify what is the property (or the combination of properties) that is causing the problem. Could you please, tell me if you see anything I could miss or could you please send us a simple example project that would show us how to reproduce the problem here?

Code: Select all

        private void button1_Click(object sender, EventArgs e)
        {
            tChart1.Clear();

            tChart1.Aspect.View3D = false;
            tChart1.Zoom.Animated = true;

            Steema.TeeChart.Styles.Points points1 = new Steema.TeeChart.Styles.Points(tChart1.Chart);
            points1.FillSampleValues(1781);
            points1.Pointer.Style = PointerStyles.Circle;
            points1.Pointer.HorizSize = 2;
            points1.Pointer.VertSize = 2;
            points1.Pointer.Pen.Visible = false;
            points1.Pointer.Color = Color.Red;

            tChart1.Export.Template.IncludeData = true;
            tChart1.Export.Template.Save("C:\\tmp\\test1.ten");
        }

        private void button2_Click(object sender, EventArgs e)
        {
            tChart1.Clear();
            tChart1.Import.Template.Load("C:\\tmp\\test1.ten");
        }

Thanks in advance.

We have a similar problem when zooming within TeeChart latest Version. Zooming doesen't work at all. We receive in all cases the IndexOutOfRangeException.

This is the exception code:

Hi Christoph,

Thanks for reporting. I could reproduce the issue here and added it (TF02013981) as a high priority item to be fixed for next releases. I'm afraid this was broken when fixing TF02013811.

Hi Narcis,

Users report the problems we reported for the 6 & 12 Feb 2009 release appear to have gone away with the 25 Mar 2009 release. Thanks.
