Python中的 Matplotlib.axis.Axis.get_snap()函数
Matplotlib是Python中的一个库,它是 NumPy 库的数值数学扩展。它是Python中用于二维数组图的惊人可视化库,用于处理更广泛的 SciPy 堆栈。
Matplotlib.axis.Axis.get_snap()函数
matplotlib 库的轴模块中的Axis.get_snap()函数用于获取捕捉设置。
Syntax: Axis.get_snap(self)
Parameters: This method does not accepts any parameter.
Return value: This method return the snap setting.
下面的示例说明了 matplotlib.axis 中的 matplotlib.axis.Axis.get_snap()函数:
示例 1:
Python3
# Implementation of matplotlib function
from matplotlib.axis import Axis
import matplotlib.pyplot as plt
from mpl_toolkits.axisartist.axislines import Subplot
fig = plt.figure()
ax = Subplot(fig, 111)
fig.add_subplot(ax)
ax.axis["left"].set_visible(False)
ax.axis["top"].set_visible(False)
ax.text(0.3, 0.5, "Snap Setting : "
+str(Axis.get_snap(ax)),
fontweight ="bold")
fig.suptitle("""matplotlib.axis.Axis.get_snap()
function Example\n""", fontweight ="bold")
plt.show()
Python3
# Implementation of matplotlib function
from matplotlib.axis import Axis
import numpy as np
import matplotlib.cm as cm
import matplotlib.pyplot as plt
import matplotlib.cbook as cbook
from matplotlib.path import Path
from matplotlib.patches import PathPatch
delta = 0.025
x = y = np.arange(-3.0, 3.0, delta)
X, Y = np.meshgrid(x, y)
Z1 = np.exp(-X**2 - Y**2)
Z2 = np.exp(-(X - 1)**2 - (Y - 1)**2)
Z = (Z1 - Z2) * 2
path = Path([[0, 1], [1, 0], [0, -1],
[-1, 0], [0, 1]])
patch = PathPatch(path, facecolor ='none')
fig, ax = plt.subplots()
ax.add_patch(patch)
im = ax.imshow(Z, interpolation ='bilinear',
cmap = cm.gray,
origin ='lower',
extent =[-3, 3, -3, 3],
clip_path = patch,
clip_on = True)
im.set_clip_path(patch)
Axis.set_snap(ax, True)
ax.text(-1.3, 2, "Snap Setting : "
+ str(Axis.get_snap(ax)),
fontweight ="bold")
fig.suptitle("""matplotlib.axis.Axis.get_snap()

plt.show()
输出:
