mpl.cbook.pts_to_prestep(x, *args)[source]¶

Covert continuous line to pre-steps

Given a set of N points convert to 2 N -1 points which when connected linearly give a step function which changes values at the begining the intervals.

Parameters:	x : array The x location of the steps y1, y2, ... : array Any number of y arrays to be turned into steps. All must be the same length as x
Returns:	x, y1, y2, .. : array The x and y values converted to steps in the same order as the input. If the input is length N, each of these arrays will be length 2N + 1

Examples

>> x_s, y1_s, y2_s = pts_to_prestep(x, y1, y2)
