3D contour plot color map

[caz]

Hi All,

I'm trying to use the 3D Contour graph (Xctrl) in LV 2009 and I have a question about the color map.  I can see how to edit the color map in the plot properties but I can't see how to fix the upper and lower limits of the scale.  I am looping through multiple frames and subsequently plotting the new data but the problem is the color map rescaling to the data in that particular frame.  I don't want this.  I want the color map to be fixed so that I can visually see how the data changes from frame to frame.  Is this doable?

Thanks,

Caz

Caz, 

  I am currently working through which specific property to change but I believe you choose the Z-Axis as your Active Axis, then change the maxium scale range and minimum scale range under the Axis section of the property node. The help file labeled 3D Graph Properties is very helpful in understanding the Properties you can change.

I am not sure if you want to automatically specify the range or the color map more so there are also color levels you can change through the Plot Specific category.

If this does not work let me know.

Important:

1. Choose Active Axis (probably Z axis)

2. Turn off auto scale

3. Then change max and min values.

If you are attempting to change the color map it is a similar process of working through the property nodes.

I'm interested in the color map and not the Z axis.  I previously did what you described for the z axis and that works fine.  You can set the max and min of the range.  I don't see the same property for the color map.  At first, I thought the Z axis and the color map would be linked but appears they are not (which is good).  Can you check and see if the color map has similar properties as the axes (autoscale, max, min)?

Color map has a similar process. Essentially whatever you do in the 3d Properties of the graph when you right click and go to 3d properties you can mimic programmatically using property nodes. If you cannot do it in the 3d properties of the graph then you cannot do it through property nodes. If you can it will be under the category shown in the picture in my previous post.
