Thank you Christopher for your reply.

I have seen some improvement in performance after implementing your suggestions. I will discuss with my team however I think we can close this for now.

Hi, Using the .Net Version=4.1.2018.5046 of TeeChart we observe slow performance of standard operations (render, zoom etc.). As an example create 5 line series each with a million points (in a standard Winform). The time to render the plot is improved if we use a FastLine series but not significantl...

Hi, I appreciate that the intermittent nature of the problem makes it hard to reproduce and we may have to reach an impasse. I cannot reproduce the problem by entering the elevation and rotation value that caused a previous error to be thrown. I can however make your demo app throw the error by repe...

Hi, Here are the results using the BeforeDraw event up to the Zoom/Rotate overflow. Hope this helps. kindest regards Test data windows\dwm\dwmapi\attribute.cpp(92)\dwmapi.dll!71833CF4: (caller: 718890ED) ReturnHr(52) tid(1234) 80070006 The handle is invalid.

Hi, Yes I have tried deleting the license file contents and additional version information entries in my VS project files. I run my application I see the evaluation banner on the 2D plot which leads me to conclude I have built with the evaluation version. I display the 3D surface plot and a failed t...

Hi, Sorry for the delay as I have been experiencing issues (on my side) updating my actual code to test the new dll. I have tested the evaluation dll on the sample code in my previous post. There is a clear improvement (with 4.2018.9.25) in successive zoom and rotate rendering of the mesh. I am unab...

Hi, There are issues with Zoom/Rotate interactions with 3D Surface plots. Essentially the mesh distorts or breaks apart and eventually asserts . The code we are using worked fine with the 2011 DotNet version ( and we have tested on more than one machine with different graphics cards) Version tested:...

Hi,

As per your explanation you can consider this closed.
Thank you again for your support

Hi Chris, I am sorry looks like my earlier reply did not post. The good news is that the fix does work as expected when I change the Theme type in the Tee Editor, thank you for this. There are still issues if you navigate to Series ... Marks Tab (in the TeeEditor) but I can I can see that may be the...

Hi, Sorry for the confusion this problem does not involve Tee files import (That was my original question). The issue here is that Theme selection through the Tee Editor sets All marker tips to be displayed. I cannot reproduce this with a single series but the (2 series) code snippet below reproduce...

Thank you for the information.

I have tried the evaluation version as you suggested.
Good news some of our issues are now resolved.
However the main issue with Themes (and MarkTips) remains.
Is there anything further we can try ?

How do I safely install/use the beta version ? I tried copying the new TeeChart.dll to my target build folder (but this does not work). My Visual Studio (VS) project automatically picks up (and builds against) the installed version 4.1.2018.5045 from the path C:\Program Files (x86)\Steema Software\S...

Thank you for the prompt reply. I have tried the TeeToTen utility and it is appears to be a one way migration tool. We were hoping for a seamless way for our applications to share a common theme/template (and for our customers to be able to create their own custom/company themes through the TeeEdito...

We have a number of licenses of TeeChart .Net and TeeChart ActiveX and one or more mixed managed and unmanaged applications using both. We would like to use a .Tee file as a standard template across our applications and this is working fine for the ActiveX v 2018 control. chart->GetImport().LoadFrom...
