If you use the axis as the first argument, like I did in my sample code, it is not possible for scatter to create a new figure to draw the points on. >> In general, to add points, I would suggest you use >> scatter(ax1, pointx, pointy, '*') >> scatter(ax(1), pointx, pointy, '*') > Let me know if you got a solution for it asap...

Thanks Walter, Any solutions for this? > If you use the axis as the first argument, like I did in my sample code, > it is not possible for scatter to create a new figure to draw the points on. > Essentially what I want to do is to plot those y1, y2 vars with the same x axes, and then plot some points on each of the y1 and y2 graphs. I have seen such graphs with Matlab before, but I don't know how to do it. Can you tell me how to do it?
