How do I combine multiple scatter charts? I have two "sales-to-cost savings" scatter charts; one showing desired outcomes and another showing actual outcomes. I want to create a single scatter chart that shows both outcomes, kinda like an overlay (see below), so that sales people can see where they are at and where they need to go. I am looking for a solution that accomplishes this desired look. Please, don't suggest alternate layouts or other ways to display data. I need all the data and plot points to apear in one chart.
