I don't have a thorough answer for you but I think I can point you in the right direction.  See the attached modified example VI.  By experimenting with the property node data you should be able to set the color for data values that are below a threshold to a color other than black.

Hello Moin,

Here is a Knowledge Base article with the instructions for the proper property node to programmaticly change the background color of a graph.

Hi:

I have been trying for long time according to this instruction. it is not working for me. The back ground color is still black.

 If you please help me, I attached the code (NI 8.5) . May be something wrong that is beyond my knowlege.

Thanks

The background color of the graph itself is not black : the point is that most of the intensity values in your data are equal to zero, thus the corresponding points in the graph are black because of the Z color scale chosen 😉

Just change the color scale for intensities, with white for zero values, and it works (see modified attached code)...

BTW, you don't need any flat sequence in the code...

Many many thanks to you.
