Smith chart throws exception in WPF

Sean Snyders · Post by **Sean Snyders** » Mon Sep 08, 2008 8:37 am

Hi,

We've implement a Smith chart using a trial version of TeeChart (TeeChart.WPF.dll version 3.5.3065.19165) and everything worked fine.

We've bought TeeChart recently and now the same Smith chart (and data) crashes our application by throwing an exception in the TeeChart API (using TeeChart.WPF.dll version 3.5.3146.24806).

We've actually tried it with another dataset (data attacted- see at bottom) and the same thing happens.
Any ideas? bug fixes?

The output is as follows for the one dataset:
--------------------------------------------------
'System.InvalidOperationException' occurred in PresentationCore.dll.

Hi Sean,

I've been able to reproduce the problem here and added it (TF02013384) to the defect list to be fixed for next releases.

Sean Snyders · Post by **Sean Snyders** » Mon Sep 08, 2008 12:27 pm

You mention that you will fix it in the next release(s). By when can we expect such a release?

We decided to buy TeeChart recently mainly because it supports Smith charts and we need Smith charts *now*.
We would have opted for a different charting library if this was not the case.

So not having Smith charts now is quite a problem for our management, as this equates TeeChart equal to other charting libraries we considered. This situation is magnified since we are still in our 30 day refund period.

Any chance you will be able to fix it soon?

Hi Sean,

Using our current sources, I could reproduce the issue using the WPFDemo shipped with TeeChart. Using the values you posted worked fine but the exception ocurred when I enabled the "2D" checkbox. Is this the same behaviour you are experiencing?

Thanks in advance.

Hi Narcís,

Yip, same here.

I load the WPFDemo, change the series to a Smith series, click 2D, and boom!, crash.

I've made a workaround in our code to select the SmithChart as a 3D chart, and then it works (to some degree). The chart is rendered correctly, it is also resized correctly, but when it has to be redrawn (e.g. changing to a different tab in our application, and then going back to the tab the charts are displayed on), then it crashes with a similar 'invalid operation' exception.

Hi Sean,

The problem is resolved for inclusion in the next maintenance release that should be available shortly.

Sean Snyders · Post by **Sean Snyders** » Tue Sep 09, 2008 8:28 am

Awesome!

Thanx for the quick support. We'll integrate the new version of TeeChart when it comes available. You have any idea when that may be? Weeks? Months?

ciao,
Sean.

Hi Sean,

You're welcome.

We haven't fixed a date for the next maintenance release. However, considering that recently a new build is published every 4-6 weeks and that last release was published on 12th August, I imagine (just my opinion) that you can expect the next release to be out before the end of this month.

I recommend you to be aware at this forum or subscribe to our RSS news feed for new release announcements.
