Is this possible: Visualize mesh of a Part + contour?

[Ben]

Use "NaN" in the Z-matrix for any point you do not want to plot.

If you posted an example of what you have so far, this would be more fun (for us) to help you.

How about a screen shot of your graph?

I am sure what you are looking at is much more interesting that the boring screen shots I posted.

"Throw us a bone!"

sure. thanks for the reply. Unfortunately entering NaN also disables the contour on that grid, what doesn't look so nice..
I'll attach you some part of the code and the plot... labview doesn't have a zoom fuction for the code, does it?

[Ben]

Cool!

How about making the contour one plot and the grid another?

[sthu]

I'm sorry, I have another stupid question:
If I displace one row, the last point does not show up any more. I could see the missing point, when I drag the plot though, but why doesn't it show up like a regular point?

The idea using two separate plots is a good one, but I will have to see how it will work out in the end - there is still a lot to do and to figure out.

It could be a bug.

Now if you had posted the code (hint, hint) an AE from NI may be able to comment.

the code for the mesh is actually the same one as in the last example, which is the same that you used in your example. or do you want the vi for that, I use? I just changed the coordinates of one row, so that they are displaced by 1 on the x axys.

another two concerns:
When I change the view I often end up having some parts of the surface not drawn. Is this a known issue, or do I just have a parameter set wrong?

Is it possible to draw a surface like a triangle?
So far the surface is defined by a 2 dimensional array for every point. I've been able to create a triangle (using the same code) when I set the all the coordinates of the first row to the same coordinate and split the second row up on two coordinates etc.. As this is hard to automize for reading coordinates out of a file, is there an easier way?

Hey guys,

I've been using the code posted above and it worked pretty well so far. Lately I ran into the situation where I had to visualize a beam. This means I have just a few points, which are in a line. In this case the code doesn't work. I always end up with a line which is the same color all way long. Is there an easy workaround?

Sthu,

Not seeing the green lines in the VI above is a bug for LabVIEW 8.5. It looks like changing the view will make everything visible. In regards to the most recent post (the beam), could you post the VI that created it? I don’t know what I should expect to see.

This was reported to R&D (#4FT9QOB7) for further investigation.
