How to handle sparse matrix like a common matrix in matlab for further analysis?

I have a big sparse matrix (coordinates spread over 4000*1000000 matrix) attached. How can I further analyze this data like plotting, histogramming, adding or subtracting data in a certain co-ordinate? I saw the 'spy' code for plotting, but I want to plot in different way like contour, imagesc etc. Can somebody please help me?

Thanks in advance Biswajit
