Hi,
I’ve created a 2D Heatmap Chart which works for itself perfectly fine (incl. x-y zooming, panning, annotations, etc.), but once I’ve added a 3D chart (even without any datapoints), the behaviour of my Heatmap chart changes. After a double click on the chart, the displayed range changes. The zoom and pan direction works only in yDirection, new created annotations are not displayed correctly anymore, previous annotations disappear, when I try to move them.

Does anyone have an idea what the problem might be?

Each chart (2D Heatmap and 3D Pointcloud) has its own view and viewmodel.
In the images below you can see the 3D chart (which I more or less copied from the examples).
The image on the right shows the heatmap chart before I created the 3D chart view. During that phase everything works fine.
The image in the middle is showing the heatmap after the 3D chart view was created.
In the meantime there is not happening much in the code. There is a message that the 3D Libraries are initialized (“INITIALIZING NATIVE LIBS IN SC3DS CTOR”). That sounds quite normal to me.

Thanks in advance,

Tim

After updating to SciChart version 4.0.6.8482 everything works perfectly fine!

Hi tim, looks pretty wierd to me!

We’re not aware of any issues and do have several examples which mix 2D and 3D WPF Charts without issue.

Can you send a simplified code sample to support (click on Support -> Open a Support Ticket) with an attachment and one of our team will be glad to investigate.

Best regards,
Andrew

I haven’t found a solution yet, but I created a small example for anyone who is interested:

A small demo video of the problem is shown here:
