Hi, I am trying to display some complex values in a polar plot. Displaying linear magnitude vs. angle - of course - works without any issues. But I'd rather display the logarithmic magnitute vs. angle. Since the data for the radius gets negative then, it'll be wrapped around / rotated by 180deg by matplotlib. How can I display negative values for the radius w/o having them rotated by 180deg? Of course I can add an offset to the data before plotting it but since my plot is interactive and I use the xdata/ydata of events I'd like them to represent the real data, without an offset. I thought it might be possible to achieve with a custom transformation but I don't actually get it to work. -Stephan -- View this message in context: http://old.nabble.com/Polar-plot---problem-with-negative-values-for-radius-tp30936638p30936638.html Sent from the matplotlib - users mailing list archive at Nabble.com. |
