The rotation and resetting of the labels isn't a big issue. The issues is when I reverse the direction. Matplotlib seems to only want to plot in an anti-clockwise direction. I can transform the data to be backwards so that it looks ok, however when it tries to connect the start and end points, it goes back around and draws a circle instead of just connecting the two points using a straight line.

A work around, that comes to my mind is resetting the label values using an idea from another mail on this list ( thetagrids( range(0,360,45), ('E', 'NE', 'N','NW', 'W', 'SW', 'S', 'SE') ) ) label_values = [item % 360 for item in range(90, -260, -45)] thetagrids( range(0,360,45), label_values) and using some well defined (linear) transformation for plotting - translating your data to the actual tick positions and corresponding labels. best regards Matthias ------------------------------------------------------------------------------ Register Now & Save for Velocity, the Web Performance & Operations Conference from O'Reilly Media.
