pcolor in polar coordinates
polarPcolor draws a pseudocolor plot in polar coordinates with a polar grid.
polarPcolor aims to represent a pseudocolour plot in polar coordinates, with a radial grid to allow clear visualization of the data. It is well suited for Plan Position Indicator (PPI) scan for radar or lidar for example . A similar function is available in ref. , which propose a visualization in 3D.

Added Github repository
The option "Origin" has been updated and is named now "autoOrigin"
Update of the example + more robust definition of "Rmin", which should not interact with the option "CirclesPos".
Three new options have been added:
Added project website
Updated the screenshot
Update the example file and added an option to change the radial tick label ('Rticklabel')
The bug related to the option "Rscale" has been correct (hopefully). A new option "Origin" has been added to let the user choose between a polar plot centred around 0 or min(R). The circles and spokes are now drawn as solid lines instead of dots.
Correction of a bug for the "Rscale" option
The html example is removed as the LiveScript file fulfils the same role
Added HTML example
Added LiveScript example
Added the possibility to include a log scale on the radial axis (see Example.m) + correction of a minor bug when theta and R have the same size.
- automatic scaling of colorbar + new example + multiple options are added
- updated for 2014b
added html example
- picture updated
- example updated
More accurate description added
