.png image to illustrate the problem

In PolarPlots, a particular thing happens which does not happen in XYPlots.
One needs to define the minimum of the Radial axis, which is the centre of the drawing circle. But this minimum could be different from the minimum displayed of the Radial axis.

In the attached example, which is a latitude-longitude plot around the South Pole, there are data between -80°S and -70°S, so that it would be appropriate to draw only this radial range. However, if one sets the minimum of the radial axis to -80, the graph is strongly distorted since -80 is placed at the centre of the circle.
Comment 1 Frédéric Parrenin 2013-03-14 10:04:09 UTC
An alternative way to implement this feature would be to add span tab to the radial axis properties.
It would be more consistent with the XYPlots properties, but on my example it would be less convenient (you have to make a calculation to put the south pole at the centre of the circle).
