Today's nugget has to do with Intensity Graphs and Intensity Charts. By default, they have a blue color map for the Z scale:
If you want to reconfigure the colors, you can right-click any of the numbers in the Z scale and choose Marker Color. It is also possible to programmatically manipulate the scale with the Color Table property of the Intensity Graph/Chart.
I have attached a VI below called Intensity Color Tables.vi that allows you to select between several pre-defined color maps for your Intensity Graphs and Charts. The VI generates the Color Table array that can be wired to the Color Table property. I think my favorite color map is "fire":
Check out the demo VI (in LabVIEW 2009 or later) to see the Intensity Color Tables.vi in action.
And this shipping example shows an practical usage of this feature:
