rose diagram

Hi,

I'm plotting rose diagrams using the function rose. I would like to have the outer circle of my rose diagram to be representative of the maximum value of the histogram.

However I found in the 'polar' function, those lines:

 cax = newplot(cax);
 next = lower(get(cax, 'NextPlot'));
 hold_state = ishold(cax);

The maximum value is defined my 'maxrho' in the polar function, however the limits of my rose diagram are calculated using:

        set(cax, 'DataAspectRatio', [1, 1, 1], 'PlotBoxAspectRatioMode', 'auto');
        v = [get(cax, 'XLim') get(cax, 'YLim')];

The results is sometimes the limits (X and Y) equal the maximum value 'maxrho', but sometimes not.

I don't understand why it is not always selecting for the maximum value? Anyone could help me to change to fix it to maximum value?

Thank you very much

The workaround I use to get the correct limits set on a polar plot is to simply draw a circle at your desired maximum, and set to the plot colour to match your background. Obviously not the nicest solution, but should work if I understand your problem correctly.

Hi, thanks.

I did the same in the end and it's fine !
