I want to create a scatter diagram graph of results in excel. But as a background on the graph I want to show regions which the results fall into. The same background would be shown on the graph if the results are updated. Its like a template graph. Can this be done in Excel, and if so, how? If not, do you have a good suggestion on another way to do this.
As an example, have attached a hand-drawn graph of what it would look like for a graph of risk results, in which lines and wording are added to show which risks are 'high', 'medium' or 'low'. 6 points have been plotted. The number and value of the points may change, but the boundaries should stay the same.
