Hello, I want to plot a curve with variables along the X & Y axis. But I also want the plot to show multiple curves as a function of another third variable. For example, if I'm plotting a curve of fruits vs. cost, I would get one curve. But how to plot it for say, seven days of the week, thus showing seven curves in the same graph. I would be doing this Matlab. So if someone could guide me with the codes. Hoping for a reply. Thanks, Prasad M. Rao.
