Inserting a Scatter Diagram into Excel. Area by Counting Squares. Beginner in R here. I was plotting some data for a colleague, had two lines (repeated experiment) per person (time on the x axis) facetted by id, I thought it’d be nice to shade the area between the two lines so that when they were deviating you’d see a large shaded area, and when they were close there would be little shading, just to aid the visual of the. the line segment between m1 and m2 is drawn; lines = 2, a line segment between the boundaries of E1 and E2 is drawn (along the line connecting m1 and m2). Once all constraint limit lines have been similarly shaded, the non-shaded portion of the graph will represent the feasible region.
