How to make a heatmap of trajectory?

Hi Colleagues,

I did the behavior test and tacked the mice. I got the position number (x, y) of mice in the field. The video rate is 30 PFS. How can I make a heatmap or color map of trajectory to indicate the mice spent more time in some region.

Thank you very much.

Like I suggested in this thread, you might want to use hist3() to create a 2D histogram of counts in each bin location. To make a larger smoother surface, rather than a chunk bar chart, you can use scatteredInterpolant.

How to interpolate data generated from hist3()? Would gridInterpolant be better?

From R2017a on you could consider using heatmap
