I'm using the wind rose by Daniel Pereira with great pleasure (https://se.mathworks.com/matlabcentral/fileexchange/47248-wind-rose?requestedDomain=www.mathworks.com)
But I have would like to make a "flux rose" with concentration instead of wind speed - there will be negative values!!
An easy way would be to put in an off set but I would much rather just have the shift around 0 indicated by colors.
Hope you can help.
