Summary

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 [1]. A similar function is available in ref. [2], which propose a visualization in 3D.

3.7

Added Github repository

3.6.2

The option "Origin" has been updated and is named now "autoOrigin"

3.6.1.1

typos

3.6.1

Update of the example + more robust definition of "Rmin", which should not interact with the option "CirclesPos".

3.6

Three new options have been added:
- colormap: Colormap for the pcolor function
- ncolor: Number of colors in the colorbar and pcolor
- circlesPos: position of the circles with respect to the origin (it overwrites Ncircles if specified)

3.5.0.3

Added project website

3.5.0.2

Description

3.5.0.1

Updated the screenshot

3.5.0.0

Update the example file and added an option to change the radial tick label ('Rticklabel')

3.4.0.0

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.

3.3.0.0

Correction of a bug for the "Rscale" option

3.2.1.3

The html example is removed as the LiveScript file fulfils the same role

3.2.1.2

typo

3.2.1.1

Added HTML example

3.2.1.0

Added LiveScript example

3.2.0.0

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.

3.1.0.0

typo
correction of a bug when Nspokes is lower than Ncircles/2
Description updated with an illustration of the method applied to wind data

3.0.0.0

- automatic scaling of colorbar + new example + multiple options are added

2.1.0.0

- typo

2.0.0.0

- updated for 2014b
- code updated
- examples updated
