Is there an upper limit on the number of points that can be plotted using a CW 3-d graph?

[Ben]

At first this was freaking me out because it looks like it worked.

I am using the W vector to define my colors so my graph iss a little different from yours.

If you change you method to "Plot3DMesh" and then run the VI, you will then be able to do the following from the front panel.

Pop-up on the graph and go to CWGraph3D >>> Properties

you will get the config screen for the graph.

Choose "Plots" tab.

Choose style >>> Plot Style >>>surface.

Then your example does the same thing I was reporting.

I believe I need to use the "plot3DMesh" method because I need to define color and the "surface" option is not available (in the config screen) until I use that method.

So...

1) I am looking at a bug,
or
2) I
do not know how to use these graphs
or
3) Fill in your ideas here.

So,
what do you think?

Here is an image that illustrates what I am after.

I had to do a 5 to 1 data reduction to get the whole surface.

I am looking for the five time increase in resolution that may data set contains but I can not display!

Ben,

It is a bug.

There might be a workaround. The control can display more then 30000 points,
if you put them in subsequent plots... So if you have 500X300 (columnsXrows)
points, you could draw the first 100 in plot 1, and line 100 to 200 in plot
2, etc. Not very nice, but it just might work...

Regards,

Wiebe.

Hi Wiebe,

Thank you for the "kick in the head"!

I will try that out this week-end.

I'll see if I can round up some more stars for you.

Hi Wiebe,

That worked!

Thank you very much for the "kick".

Kileen,

Let me know if I have to call to get this bug reported and fixed.

Now all I need is a 50GHz proccesor and I am in buisness!

Ben

[Wiebe@CARYA]

Good to here!

Regards,

Wiebe.

Hi Ben,

This problem has been reported already as a bug and R&D is working on fixing the ActiveX 3D Graph Controls for the next release of Measurement Studio. I have also added a link to this Discussion Forum posting to the bug report for them to reference.

Thank you again.

Hi Kileen,

You said,

"R&D is working on fixing the ActiveX 3D Graph Controls for the next release of Measurement Studio"

Are you sure this will be fixed in the next version?

What is the CAR # ?

Ben

[KileenC]

Hi Ben,

R&D has been aware of this issue for some time and are working on rewriting the 3D Graph Controls code entirely. Two CARs have been filed: 2Y8DKL5E, 36NDCGPC.

Thanks again.

Kileen C.

Thank you!
