I've a large data make matrix 100*100 and and other two sets of data represent the x and y axis. Each value in the matrix is a related to one value in x and one value of y. I ask about a way to plot these data list contour plot and about how to combine this figure with list log plot and I don't want to write the the data manually Thanks in advance
