Hi All, I'm looking at plotting the response of devices on a polar plot, either 2D or 3D. In this cases it's the response of a field probe. Several plots will be used for different frequencies. Does anyone have suggestions of what package to use? I know or Origin, but it's very expensive. Cheers, Derek N. Walton Owner L F Research EMC Design and Test Facility Poplar Grove, Illinois, USA www.lfresearch.com Derek: You can do this for free, right from Excel or MS Word. If you choose Excel, then just enter two columns of data, XY pairs of degrees and magnitude. Then, click the chart wizard, and choose the "radar" style, either 2D or 3D. That's it. I always have trouble setting up new charts, what with MS's non-scientific orientation of chart & data formats. Once I build a chart or plot that I like, I usually copy it, and just stick in new data and labels for subsequent charts. Anyway, it's free, colorful, and seduces you into spending more time than you should building a dumb chart.
