Hello,

We're unable to reproduce the problem in RAD Studio 12 (Version 29.0.53982.0329 ). Are you able to send us a small sample project that reproduces the issue. Tested with with VCL C++ x64.

Thank you for the error report. We are checking the issue.

Hello,

You can use the alternative events in the paint cycle to (z) position your plot:
this order:

• BeforeDrawAxes

• BeforeDrawSeries

or (last as you are using now)

• AfterDraw

Hello, This issue has been a moving target, resulting with correct functioning for certain RAD Studio 12 patch releases. As you point out, it only affects C++ projects. We are checking this now with RAD Studio update 3. For your purposes, it may be acceptable to you (?) to disable the _Headers prope...

Hello,

Yes, the error has appeared again for the latest C++ Windows x64 but works fine with modern C++ Windows x64. We'll take another look. Embarcadero recommends the use of modern.

Hello, TeeGrid version 1.15 was built for RAD Studio 12.1. patch 1, if you have that version of RAD Studio (I don't have a record of whether that covers the build number you have sent). Embarcadero introduced several bugfix releases in close succession, that resolved issues for x64 compilation. ref:...

Hello,

The issue was caused by use of the non-latest version of the Athens IDE. The issue was fixed by Embarcadero for the next 12.2 build. Please be sure to be using the latest version of RAD Studio 12.

ie.

Embarcadero® RAD Studio 12 Version 29.0.53982.0329

Hello, We are looking at the issue. In the meantime we offer a workaround: It uses a boolean variable to force a one-time repaint for the scroller after changing to inverted: eg. open scope variable: var hasPainted; //set to false in main draw() routine. //------ to run before chart.draw() in main e...

Hello, If you run a cross-check you can confirm that the Labels have been added for the plot. For example, with a Listbox on the form: private void tChart1_AfterDraw(object sender, Steema.TeeChart.Drawing.IGraphics3D g) { listBox1.Items.Clear(); for (int i=0; i < tChart1.Axes.Bottom.Labels.Items.Cou...

Hello, There are some options to control the panning (scroll), examples here below, including changing the mousebutton used for Panning: //add extra key control to enable panning tChart1.Panning.KeyShift = Steema.TeeChart.Drawing.Keys.Shift; // swap keys for scroll and zoom and deactivates zoom. (so...

Hello Srikanth,

The requirement looks similar to the question posted here:

C# library running TeeChart being called from client app

Note the use of "[assembly: EntryAssembly]" in the AssemblyInfo of the consumed dll (where TeeChart is being used).

Marc Meumann

as a followup. The issue has been resolved for the next release.

There's a TeeChart bug here. Custom axes stats don't correctly update after a zoom (like they do after a scroll/pan). We'll fix it. Thanks for reporting the issue.

The Chart needs to have calculated the axes before settings items will work, normally a start, once only, repaint resolves that. But anyway if you want to zoom the axes and require a change of labels, then the labels will require updating and the callback should be used. I'll modify the example and ...
