intensity graph in gray scale

[bruno_dickinson]

Hi,
I'm trying to use a intensity graph in gray scale,but i have been finding it hard to do.
In my application,i use a 3d parametric surface in gray scale,and in this graph i know how to set the color map.
My problem is that in the intensity graph,i can't set the colors i want in that color table beside the graph's indicator.
What i want to know is how to set this color map in the intensity graph with the colors i want for the maximum,minimum and medium values. Something like setting the minimum value to black,the maximum to white and a gray level for the medium value.
Thanks for the attention.

Hello Bruno:

You might try using the PROPERTY values to programmatically change the width of the line..this might be a bit more visible than the intensity alone. I believe there may be an actual "gamma" function as well, which gives you more control over the dynamic range of intensity values. (Try out a LOG display of the Z axis to see if this works for you, as well. YOu can set arbitrary points in the z axis in either grayscale or color. (By the way, you cannot set the color levels if the "interpolate color" is on. Disable it first, then you can set the color levels)

Hope you can use at least one of these tricks!

Good luck!
