2D projection of contour plot

[MOI_maker]

Hello

I know there are a lot of threads around about contour plotting, but everyone seems to want 3D graphs, I just want a 2D projection of one, with the z values represented by level curves in the xy plane.

I have been using the attached example to create something similar to what I want: I set "plot type" to cwSurfaceContour and make both "XY projection" and "Show projections only" true.

The result is exactly what I am looking for except that I want the z axis gone. Just a normal 2D plot.

Thanks in advance,

Steve

If you have LV 2011, look in the Mathematics/Computational Geometry palette - there is a new VI called Contour Line which will do what you want.  There is also an example which shows how to use it.

Hmmm... I only have 2009. Guess it's time to update.

There is a contour control in LV2009, though it is a 3D one. You can mimic a 2D contour by clicking the XY button on the projection palette.

If you want to gain better performance since 2D is enough for you, try Contour Line.vi in LV2011.
