3D surface plot colors

[Dirk@LV]

I am trying to understand the functionality of the color vector input of the new 3D graph plot line VI, in combination with the 3D graph property Surface Color Map. Could not find any documentation on how these default or overwrite each other or how to use them. I thought that the color vector input could be used to set a color directly to form a 1:1 correspondence with the z-vector input, but that does not seem to be the case.

I have successfully used the color ramp of an intensity graph to change the color gradient of the 3D line, as in several examples for the CW3D graph. However, when I increase the color range by editing the min/max values on the color ramp, also the 3D line should then show only a subset of the full color ramp spectrum. I guess that should be somehow possible using the color vector and/or color map property ?

Thanks in advance,

Dirk

Starting at post # 7 of this thread you will find a series of posts that were intended to serve as a worse case introduction to the CW 3D graph.

You will find text to go with these images in that thread.

Thank you, Ben. Actually I want to use the newer 3D line graph.vi, not the original CW 3D graph. But the CW 3D examples in the thread you mention helped me to figure it out. The general concept seems to be the same. If I am right the "color vector" is replacing the magnitude "W" and the "Surface Color Map" property combines the ColorMapValues & ColorMapColors of CW 3D. Things would be easier if the multiple properties and methods of the new 3D graph class would have been documented in more detail. Especially for those that have undergone name changes...

Anyway, thank you for your help.

Ditto that!

You should have seen what it was like uisng the Public Beta version of the 3D graph where there was zero documentation and was implemented in LVOOP.

I suspect the issue with documentation with the 3D graphs comes down to finding some that can both write in english and understand the 3D graph. Anyone that is smart enough to understand the 3D graphs gets sucked into the ivory tower.

Would it be possible for you to please post a simplified example that would help others trying to make the same leap you just completed?

Take care,

Ben

Here is an example with my "findings", hope they are correct. As we all have so much spare time, it is much fun to reverse-engineer the internal algorithms by trial-end-error...

The example is in LV10.
