Dear Philippe,

The BAR update site[1] has several scripts that use the jfreechart library[2] (bundled with Fiji) to perform advanced plotting from within ImageJ (see some examples here[3]).
I just uploaded a script[4] that allows you to create polar plots (XY lines plotted in polar coordinates - see this screenshot[5] to get an idea on how it looks like). Once you subscribe to the BAR update site, you will find it under "BAR>Data Analysis>Create Polar Plot." A cool feature of all these "BAR>Data Analysis>" commands is that they can read tabular values from multiple sources, not just the ImageJ Results table.
You could use it as a starting point for your polar histogram chart.
(It would be great if you could add such functionality to the existing script[6]).
