Python中的 Matplotlib.figure.Figure.show()
Matplotlib是Python中的一个库,它是 NumPy 库的数值数学扩展。 figure 模块提供了顶级 Artist,即 Figure,其中包含所有绘图元素。该模块用于控制所有绘图元素的子图和顶级容器的默认间距。
matplotlib.figure.Figure.show() 方法
matplotlib 库的show() 方法图形模块用于显示图形窗口。
Syntax: show(self, warn=True)
Parameters: This method accept the following parameters that are discussed below:
- warn : This parameter contains the boolean value.
Returns: This method does not returns any value.
下面的示例说明了 matplotlib.figure 中的 matplotlib.figure.Figure.show()函数:
示例 1:
# Implementation of matplotlib function
import matplotlib.pyplot as plt
import numpy as np
fig = plt.figure()
x = np.arange(20) / 50
y = (x + 0.1)*2
val1 = [True, False] * 10
val2 = [False, True] * 10
plt.errorbar(x, y,
xerr = 0.1,
xlolims = True,
label ='Line 1')
y = (x + 0.3)*3
plt.errorbar(x + 0.6, y,
xerr = 0.1,
xuplims = val1,
xlolims = val2,
label ='Line 2')
y = (x + 0.6)*4
plt.errorbar(x + 1.2, y,
xerr = 0.1,
xuplims = True,
label ='Line 3')
plt.legend()
fig.suptitle("""matplotlib.figure.Figure.show()
function Example\n\n""", fontweight ="bold")
fig.show()
输出:
示例 2:
# Implementation of matplotlib function
import numpy as np
import matplotlib.pyplot as plt
x = np.linspace(0, 10, 500)
y = np.sin(x**2)+np.cos(x)
fig, ax = plt.subplots()
ax.plot(x, y, label ='Line 1')
ax.plot(x, y - 0.6, label ='Line 2')
ax.legend()
fig.suptitle("""matplotlib.figure.Figure.show()
function Example\n\n""", fontweight ="bold")
fig.show()
输出:
