I would like to plot a matrix of data using gradient of colors (say red and yellow) . I have hunted through multiple forums and posts - I have been unable to find a solution that meets the needs . Would appreciate some guidance .
I am attaching a figure that I was able to generate using binary matrix - I would like similar plot for a matrix which is not really binary ( but multiple values) and the values always range between 0 and 1 .
This seems to work fine - but I dont know how to customize the plot - by adding axes.
