Matplotlib 向左移动绘图图

Question

I'm wondering if it is possible to shift the graph only to the left for the following plot graph.

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

# Data for plotting
t = np.arange(0.0, 2.0, 0.01)
s = 1 + np.sin(2 * np.pi * t)

fig, ax = plt.subplots()
ax.plot(t, s)

ax.set(xlabel='time (s)', ylabel='voltage (mV)',
   title='About as simple as it gets, folks')
ax.grid()

fig.savefig("test.png")
plt.show()

I want to leave the x ticks the same but want to shift the graph so that the starting point of the graph is on y-axis. Any suggestions?

Thank you in advance.

您可以通过更改 x 轴上的限制使线的起点位于 y 轴上

ax.set_xlim(xmin=0)
