Contour plot

[Anonymous]

I know this topic has been discussed many times, and Ben gave some good
suggestions and examples. But I still need help on the contour plot.
I am trying to generate a contour plot similar to the contourf function
in Matlab. With the x-y projection property, I can get a similar plot,
but the x-axis label orientation is toward right instead of up. I
looked through all property nodes, there is no way to change it. Also,
the axis label looks ugly (too big). Is there any better way to do
this?

I also tried calling Matlab. But the program will be released as an
excutable program. I need to bother Matlab compiler.

If you have Office 2003, you might be able to use an Excel surface chart as an activex object. Then set the property for contour.

Thanks for the nice words. You wrote;

"...looks ugly..."

That is a very difficult question to answer. "Beauty in the eye of the beholder." W. Shakespear (sp?)

Please post an image of what you think is NOT ugly and we will better able to serve you.

Thank you,

Ben

Thanks. I'll check it.

Overall I am quite satisfied with the 3D plot of Labview, but my boss
doesn't like it. After spending a few days in stand-alone matlab
program, I come back to Labview's 3D surface contour plot. There are
two many limitations on stand-alone Matlab applications, e.g., which
can't load data from an Ascii file.

Do you work for NI, Ben? Currently my biggest program with Labview plot
is the x-axis label orientation. Also the label text is not on scale if
the graph box is not a square. I don't know much about ActiveX control.
Just wondering if it is possible to plot 3D graphs like 2D graphs, so
we can directly change axis limit, colormap on the graph. It seems many
people look for solution that is similar to Matlab's 'contouf'
function. It will be nice to have a 2D contour function in Labview.

Thanks again for the scale.vi. I am going to use it in my current
project.

"Do you work for NI, Ben? "

No. Like everyone who's icon has "gold bars" under it, I am just a volunteer who tries to help others with the challenges in LV.

It is possible to to plot contours on an "XY-graph". You (as the devloper) will have to code the logic to determine what the "projection" of each level you want to illustrate.

Otherwise, I have not seen a "matlab" contour plot in at least 7 years so refering to Matlab does not do me much good.

As is always the case in any language, if the native functionality is not good enough, well then you will have to develop your own.

If you come up with a good work around I'd love to see the results!

Sorry we were not able to help you,

Ben
