Good morning,
I have points with coordinates (x,y) in 2D cartesin system. The points cover a circler zone and each point have a value of temperature.
I would like to plot an image with temperature colorbar which means a filled colored circle and the color varies with temperature (see attached filecercle_colore.gif).
I appreciate your help.
Regards

Maybe you could adapt this:

or this:
https://uk.mathworks.com/matlabcentral/fileexchange/49040-pcolor-in-polar-coordinates
After converting your points to polar coordinates using cart2pol.
I don't see an easy way to do what you want using inbuilt functions unless you build your own plotting function...
