How to programmably control the 3D plot, switching from greyscale to colorgram?

[BLpig]

I am using the 3D parametric surface vi to plot a 3D matrix. It should be displayed either as a colorgram or greyscale plot, controlled by the users. But currently it seems like I just can stop running the program and then manually right click the display area, select the 3D plot properties to change ... How can I realize this by programming? Thanks.

Hi BLpig,

Hope this example will help you!
It's made in Labview 7.0!

hi, thank you so much! It works for me.
But one more step is, I also need to change the colormap or the colorvalues property as well (do they need to specify together?) since like for greyscale, I want to have my 0 value mapping to white and 3.5 value mapping to black. I think maybe I can work this out with the CWPlot3D.ColorMapColors and ColorMapValues ... but haven't figure out how to do it.

How to do this?

Hi BLpig,

I changed the example so it is possible to change the colors and values during runtime.
Some explanation is in the example!

Hope this will solve your problem!

hi, it works perfect for me now. Thank you so much!

Here is a little note from somebody who wasted a lot of time before finding this example...

It is REALLY important that the ColorMapAutoScale property is set to false BEFORE you change the ColorMapValues.
I never new that the order of the elements in property nodes was important. Here it is!

The example is correct - my code wasn't. Thanks for the example.
