step

mipylib.plotlib.miplot.step(x, y, *args, **kwargs)

Make a step plot.

Parameters:
  • x – (array_like) Input x data.
  • y – (array_like) Input y data.
  • style – (string) Line style for plot.
  • label – (string) Step line label.
  • where – (string) [‘pre’ | ‘post’ | ‘mid’]. If ‘pre’ (the default), the interval from x[i] to x[i+1] has level y[i+1]. If ‘post’, that interval has level y[i]. If ‘mid’, the jumps in y occur half-way between the x-values.
Returns:

Step lines

Examples:

x = arange(1, 7, 0.4)
y0 = sin(x)
y = y0 + 2.5
step(x, y, label='pre (default)', color='b', linewidth=2)
y -= 0.5
step(x, y, where='mid', label='mid', color='r', linewidth=2)
y -= 0.5
step(x, y, where='post', label='post', color='g', linewidth=2)
legend(loc='lower left')
xlim(0, 7)
ylim(-0.5, 4)
