Hey,

I have a data called normal contact forces (around 10000 values in a column). I want to draw a polar histogram to represent the data (only using 0 to 180 degrees angle) such that the radial length of each bin gives the number of contact forces present in the angles bounded by the bin. And The colour should be proportional to the average normal contact force that is oriented in each bin normalized by the total average normal force within the entire sample.

I am also attaching the data for your reference.

Can anyone please help me in this regard.

best wishes

Sarath

Hi,

Kindly have a look at the following links

https://www.mathworks.com/help/matlab/ref/polarplot.html (Polar Plot)
https://www.mathworks.com/matlabcentral/answers/184607-rose-diagram-for-discrete-data (Rose diagram)
https://www.mathworks.com/help/matlab/ref/polarhistogram.html (Polar Histogram)

Note that rose is not recommended and polarplot has additional functionalities over polarhistogram.

Thanks

@Prabhan Purwar Thank you for the reply. I have already checked these links before. My question is more specific towards the details of the things that can be put in the polar plot/polar histogram. Can you please help with detail reference or code to that.

Thanking you in advance
