I use wpf and chart version 6.1.0

I am a work that draws on the spectrograms receive real-time data.
Windows 8 (64bit) installed touch-based notebooks "ASUS TransformerBook" following problems are occurring.

The spectrograms problem disappears when the surface sizeZ change. sometimes ( ex. surface.SetSize( surface.SizeX, 25600 ); )
Did not change the settings of the chart or surface. Just, surface sizeZ change.

but, No surface clear, Never call SurfaceGridSeries3D.Clear();
MouseTraceCell also a function of the surface normal operation.
In other PC that this problem does not occur. :cry:

"ASUS TransformerBook" :
processor - intel core i7-4500U CPU, 1.80GHz 2.40GHz
Memory : 4.0 GB
System Type : 64bit( x64 )
window : window 8 K

I think it runs out of memory. The memory allocation needed for SizeX * 25600 intensity array is huge.

Please try running with a smaller array, at least to trouble-shoot the problem. Don't shoot me though 8-)
