Matplotlib是Python中的一個庫,它是數字的-NumPy庫的數學擴展。 Figure模塊提供了頂層Artist,即Figure,其中包含所有繪圖元素。此模塊用於控製所有圖元的子圖和頂層容器的默認間距。
matplotlib.figure.Figure.get_constrained_layout()方法
matplotlib庫的圖形模塊的get_constrained_layout()方法用於獲取是否使用了受約束的布局。
用法: get_constrained_layout(self)
參數:此方法不接受任何參數。
返回:此方法返回是否使用約束布局。
以下示例說明了matplotlib.figure中的matplotlib.figure.Figure.get_constrained_layout()函數:
範例1:
# Implementation of matplotlib function
import matplotlib.pyplot as plt
from matplotlib.lines import Line2D
import numpy as np
from numpy.random import rand
fig, ax2 = plt.subplots()
ax2.bar(range(10), rand(10), picker = True)
for label in ax2.get_xticklabels():
label.set_picker(True)
def onpick1(event):
if isinstance(event.artist, Line2D):
thisline = event.artist
xdata = thisline.get_xdata()
ydata = thisline.get_ydata()
ind = event.ind
print('onpick1 line:',
np.column_stack([xdata[ind],
ydata[ind]]))
elif isinstance(event.artist, Rectangle):
patch = event.artist
print('onpick1 patch:', patch.get_path())
elif isinstance(event.artist, Text):
text = event.artist
print('onpick1 text:', text.get_text())
print("Value return by get_constrained_layout():",
fig.get_constrained_layout())
fig.suptitle('matplotlib.figure.Figure.get_constrained_layout() \
function Example\n\n', fontweight ="bold")
plt.show()
輸出:
Value return by get_constrained_layout():False
範例2:
# Implementation of matplotlib function
import matplotlib.pyplot as plt
import numpy as np
from matplotlib.patches import Ellipse
NUM = 200
ells = [Ellipse(xy = np.random.rand(2) * 10,
width = np.random.rand(),
height = np.random.rand(),
angle = np.random.rand() * 360)
for i in range(NUM)]
fig, ax = plt.subplots(subplot_kw ={'aspect':'equal'})
for e in ells:
ax.add_artist(e)
e.set_clip_box(ax.bbox)
e.set_alpha(np.random.rand())
e.set_facecolor(np.random.rand(4))
ax.set_xlim(3, 7)
ax.set_ylim(3, 7)
print("Value return by get_constrained_layout():",
fig.get_constrained_layout())
fig.suptitle('matplotlib.figure.Figure.get_constrained_layout() \
function Example\n\n', fontweight ="bold")
plt.show()
輸出:
Value return by get_constrained_layout():False
