Your easiest option is probably to use a cursor's horizontal line -- place it with an X value that is offscreen and turn off its Allow Drag property on the diagram if you don't want the user to move it. Another option is simply to add another plot with points that go from edge to edge. If you already have a multiplot, just bundle in another. If you currently have a single plot, make an array of your current type and add another element. Greg McKaskle
