It is possible to convert a signal representation of a time series like the one shown in the attached picture (left) into a density color image (right)? Red values show the most visited (v,w) points in the representation.
Thank you!

You can create a sum image. Every time you visit some (row, column) location, just increment the sum image, like
sumImage = zeros(1000, 1000); % Whatever.
for k = 1 : 1000000
% Somehow get a new row and column or x,y. Then
sumImage(row, column) = sumImage(row, column) + 1;
imshow(sumImage, 'Colormap', turbo(256));
