轴线样式

此示例展示了轴线样式的一些配置。

注意：mpl_toolkits.axisartist 轴类可能对新用户来说令人困惑。如果只是为了在轴的末端获得箭头，请查看带箭头的居中脊柱 示例。

import matplotlib.pyplot as plt
import numpy as np

from mpl_toolkits.axisartist.axislines import AxesZero

fig = plt.figure()
ax = fig.add_subplot(axes_class=AxesZero)

for direction in ["xzero", "yzero"]:
    # adds arrows at the ends of each axis
    ax.axis[direction].set_axisline_style("-|>")

    # adds X and Y-axis from the origin
    ax.axis[direction].set_visible(True)

for direction in ["left", "right", "bottom", "top"]:
    # hides borders
    ax.axis[direction].set_visible(False)

x = np.linspace(-0.5, 1., 100)
ax.plot(x, np.sin(x*np.pi))

plt.show()
