You can configure the 3d graph to show you the project onto any of the planes you wish. Running inside the labview IDE I can use the MatScript node and the matlab "contour" function, but this app requires building into an exe and running under the labview runtime engine (which apparently you can't do with matscript functions.)Īnyone know any good solutions for doing this? Any suggestions welcome (I'd probably even pay for an add on if one existed. pre-existing) labview code that will let me do this? I can't imagine that I'm the only one who's interested in doing this with data acquired in labview. I can get nice looking intensity plots of the data, but I want contour lines (with user selectable dB interval).
The ideal solution would be to have a genuine 2D plot with the contour lines on it (as opposed to using the 3D activex graphy thing), but I can't see anywhere within labview how to do this. so it's not at all obvious where on the flat projection of the contour plot the cursor is actually placed. But we want to be able to make cursor measurements on the plots as well, which is where things get tricky - although we can make the 3D plot simulate a flat, 2D contour plot, the cursors within the 3D plot are always in 3D. At the moment, we have manage to achieve this using the 3D plots in labview (8.6). For the type of measurement we're doing a dB contour plot of the data is extremely useful. One of the functions of the measurement system is to acquire 2D data "maps" and then process the data and display it to the user.
We have a whole suite of software written now in labview for control and acquisition with the system and (separately) for post processing acquired data.
