我正在尝试在两个y轴上绘制两条曲线，如图所示。但是即使我将红色图（压力）的zorder设置为1和2，绿色图（针升力）也将绘制在主轴图上方。

我使用的代码：

import numpy as np
import matplotlib.pyplot as plt
from matplotlib import ticker as tick
data = np.genfromtxt("secondary_axis.dat", skiprows = 2, delimiter = ',')
time = data[:, 0]
pressure = data[:, 1] * 0.006894759086775369
pressure_charge = data[0, 0]
needle_lift = data[:, 2]
figure = plt.figure(figsize=(5.15, 5.15))
figure.clf()
plot = plt.subplot(111)
plot.plot(time, pressure, label = r'\textit{Raw}', zorder = 2)
plot.set_xlabel(r'\textit{X}', labelpad=6)
plot.set_ylabel(r'\textit{Y}', labelpad=6)
primary_ticks = len(plot.yaxis.get_major_ticks())
ax2 = plot.twinx()
ax2.plot(time, needle_lift, color='#4DAF4A', zorder = 1)
ax2.grid(False)
ax2.set_ylabel(r'\textit{Z}', labelpad=6)
ax2.yaxis.set_major_locator(tick.LinearLocator(primary_ticks))
plt.show()

而且数据可在这里

如何使用matplotlib将绿色（针升）图放置在红色图（压力）下方？

使用rc设置更新了代码

import numpy as np
import matplotlib.pyplot as plt
from matplotlib import rc_context
from matplotlib import ticker as tick
