I want to draw a plot figure in which the rectangular background region corresponding to x-coordinate [1, 100] has a red color, [101, 150] has a blue color and [151, 220] has a green color. This thread proposes a method to set background color but it only sets the whole background of the plot. Is it possible to set different part of the background with different color? Thanks a lot!

You can get the y limits using ylim(), then you can use patch(), fill(), or rectangle() to draw different colored rectangles knowing those x ranges and y ranges.
