Matplotlib是Python中的一个库,它是数字的-NumPy库的数学扩展。 Artist类包含用于呈现到FigureCanvas中的对象的Abstract基类。图中所有可见元素都是Artist的子类。
matplotlib.artist.Artist.get_snap()方法
matplotlib库的艺术家模块中的get_snap()方法用于获取快照设置。
用法:Artist.get_snap(self)
参数:此方法不接受任何参数。
返回:此方法返回捕捉设置。
以下示例说明了matplotlib中的matplotlib.artist.Artist.get_snap()函数:
范例1:
# Implementation of matplotlib function
from matplotlib.artist import Artist
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(Artist.get_snap(ax)),
fontweight ="bold")
fig.suptitle('matplotlib.artist.Artist.get_snap()\
function Example', fontweight ="bold")
plt.show()
输出:
范例2:
# Implementation of matplotlib function
from matplotlib.artist import Artist
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)
Artist.set_snap(ax, True)
ax.text(-1.3, 2, "Snap Setting:"
+ str(Artist.get_snap(ax)),
fontweight ="bold")
fig.suptitle('matplotlib.artist.Artist.get_snap()\
function Example', fontweight ="bold")
plt.show()
输出:
