Hi all, I want to create a pie chart (Nightingale Rose Chart) Does anyone know how to do this?

This pie chart is an example of what I would like to achieve.

Hopefully this makes it a bit clearer. Thanks in advance!

It looks like polarhistogram is what you want. It looks like you will need to scale your data to be from 0 to 2pi and text can be put in with the text command. I am not sure how you could do color but it may be possible.

Hi,

In my understanding the pie charts you are trying to plot can be drawn using polarhistogram. From the figure you have attached I can see there are 6 bins in the polarhistogram object.

I am assuming you have the background figure that is similar to a map. So, you can generate the individual polarhistogram using below code:

close all 
p = polaraxes; 
polarhistogram(p,'BinEdges', linspace(0,2*pi,7),'BinCounts',[0.3 0.1 0.2 0.8 0.57 0.7]); 
p.RLim = [0 1]; 
p.ThetaTick = []; 
p.RTickLabel = {}; 

The ‘BinCounts’ parameter can be changed based on the values you have in each category.

For Adding Multiple polarhistogram you may use App Designer. In that you can add multiple Polar Axes on top of the figure that contains the map. For drawing polarhistogram you need to have the positions of the axes.

Currently for plotting Nightingale Rose Chart directly with a function is not supported. You may use App Designer for plotting separately every individual object.

You may refer to following for using App Designer:
