>I am trying to plot four lines, and fill in the area bounded below by two of them and above by two of them. I create three different plots, covering three abutting regions, so that the area between functions 1 and 3 is filled in the first, then the area between functions 1 and 4, and finally no area is filled. I then combine all three plots using show, and obtain a cohesive graph showing exactly what I want.
>The problem arises when I add a legend. It seems I cannot add a legend to the Show command. When I add a legend to the third plot, which is the rightmost, the legend appears in that plot, but disappears when combined in Show. How can I display a legend in the final graph?
