I have 4 times series with different scale but they move in line with each other. i want to plot them into same graph but then the result is not so nice. The time series that has little change become almost flat when plotted against a more volatile series. althought hey actually move together. but in the graph we can't see it. I can plot 2 series of different scale by using Y axis on both left and right hand size. And the graph looks nice for 2 series. But here, now I have 4 series to compare. what should I do??any help would be highly appreciate.
