mplutils.convert_to_steps

mplutils.convert_to_steps(x, y, start_at=0.0, xlim_lower=None, xlim_upper=None)

Convert (x,y) data to steps.

Parameters:

xarray_like

x data, corresponding to the centers of the resulting steps.

yarray_like

corresponding y data.

start_atfloat or “auto”, default 0.0

Start/end steps at this value.

If “auto”, start (end) at first (last) y value.

xlim_lower, ylim_uppperfloat, optional

Lower/upper limits of the range.

At least one limit must be provided if x data doesn’t have constant spacing. If both lower and upper limits are provided, the lower one will be prioritized.

Returns:

x, yndarray

Data corresponding to steps.

Examples

import matplotlib.pyplot as plt
import numpy as np
import mplutils as mplu

x = np.linspace(1.0, 10.0, 9)
y = 2.0 * x

_, axs = plt.subplots(1, 3, layout=mplu.FixedLayoutEngine())

axs[0].plot(x, y, "-")
axs[1].plot(*mplu.convert_to_steps(x, y), "-")
axs[2].plot(*mplu.convert_to_steps(x, y, start_at="auto"), "-")

for ax in axs:
    mplu.set_axes_size(2.5, aspect=3.0 / 4.0, ax=ax)
