Re: Custom tick grid line color
Hi matus,
v.7 allows controlling grid and tick colors individually. You can give specific colors to tick and grid by adding two custom ticks. One tick for the tick (customTick.Style = Tick), and one tick for the grid (customTick.Style = Grid).

You can achieve that best by placing SeriesEventMarker on each data point location. You can give individual color and shape for every marker, and you can have thousands of them in the chart. To hide the label of the marker, set marker.Label.Visible = False.
I hope this helps![Wink ;)](./images/smilies/icon_e_wink.gif)

Re: Blank display of SurfaceMeshSeries3D
using 2000x143 surface mesh will take about 800 MB of memory on GPU.
What is the GPU type you are running with?
Please use GPU-Z utility and observe the GPU memory consumption. How high does it go?
If you subscribe to chart.ChartError event handler, does it report anything?

Yes. It wasn't applied yet in our 7.1.1 release. Source code subscribers can increment the number. In next release this will be included.

Re: Blank display of SurfaceMeshSeries3D
Hello.
In 7.1 we added Value-based coloring in surface series. It means we had to add Value field in SurfacePoint structure. It leads to slightly bigger memory consumption. Please compile & run your app in 64-bit mode and let us know if solves the problem.

Is that after you selected Billion points example and then switching to this, or directly when opening this example?

Re: System.AccessViolationException
Thanks for reporting the problem.
To be clear, are you running with Surface Pro tablet, what model exactly? If you run the examples with a real PC, do they still crash for you?

Hello,
The version is still 3.0.0.0 as it's different thing than other LC dlls, it an assembly made with ILMERGE from SharpDX dlls. I've requested our team to increment the number on every build, to prevent problem in the future.

Re: Initial palette loading
Hello,
precompiled shader count is 19 steps in 7.0.2.18 onwards.
To increase the step count, you will need LC source code. Higher precompiled step count means slightly longer delay in initialization of also low step count applications, but greatly improves initialization time with high counts.

Re: Stacked bar series
I believe the chart doesn't support it out-of-the-box.
One approach is to compose it with PolygonSeries. One 4-corner polygon for each bar, and calculate their locations by code.

Re: How to select the used GPU
Thanks for pointing us to correct direction. According to that MS page, it should be possible in DX11. In DX9, not.
We will do further research on this and if possible, add functionality to prefer high-performance GPU when ever available.

Re: How to select the used GPU
There's unfortunately no way for us to select that programmatically. LC renders with hardware it's given to, by the system.

Re: How to select the used GPU
Hi,
Right-click on your desktop and select "NVIDIA control panel".
You should find a place where to control the applications that use Nvidia for rendering. Set "NVidia high-performance graphics" as global setting. Reboot is typically needed.
