graph library (Labwindows/CVI)

[kao]

I want a graph like smith chart on which I plot polar data ( amplitude and angle) . I cannot find library that supports the feature. Any suggestion.

I'm not sure what version of CVI you are using (you should always say your version when posting), but if you are using CVI 5.0.1 or above, there is a Smith Chart example program under cvi\samples\app\smithchart\smithdem.prj.

With CVI 5.x comes an example in the cvi\samples\apps directory called smithdem.prj, which demonstrates the use of a graph to generate a smith chart. This is done through the use of the smith.fp instrument driver that you can see used in this example.
