I have x and y coordinates of animal inside a circular arena. I am using hist3 in Matlab to plot a heatmap. I would like to visualize it inside a circle, instead of the default a square with axes (left).
What I would like is this: A circle showing the heatmap, with the white outside. This is just acircle plotted on top and its not aligned properly, because I had trouble passing the centre and axis limits.
I am using hist3 and then imagesc to plot.
Any ideas how to achieve this?
