It's a boolean array with the same size as x. import math import matplotlib. plot(x, y1) and plt. The curves are defined by the points (x, y1) and (x, y2). Here is a simpler case for the 1D case using the fill_between function. The usual way would be to utilise imshow for this task. If you set levels=30 there will be 30 such lines drawn. The fill_between function is used to fill the space or region between two horizontal curves or lines. Each polygon is defined by the lists of x and y positions of its nodes, optionally followed by a color specifier. fill_between function only requires to put the maximum array and minimum array for your proposal of equal length of OX array (time in your case).
