It has data for the same four cities, with the line charts in the four panels, arranged horizontally. new()signals to R that a new plot is to be produced. This is a plot option and should be placed in the square brackets after the addplot command. In fact, the number pi, the standard definition for it, is just the ratio between the circumference and the diameter of a circle. This is where we want polyCurve() to be run, so the coloured polygons end up being drawn underneath the actual data.

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.
