Matplotlib是Python中的一個庫,它是數字的-NumPy庫的數學擴展。軸類包含大多數圖形元素:Axis,Tick,Line2D,Text,Polygon等,並設置坐標係。 Axes實例通過callbacks屬性支持回調。
matplotlib.axes.Axes.xaxis_inverted()函數
matplotlib庫的axiss模塊中的Axes.xaxis_inverted()函數返回x軸是否反轉。
用法: Axes.xaxis_inverted(self)
參數:此方法不接受任何參數。
返回:此方法返回x軸是否反轉。
以下示例說明了matplotlib.axes中的matplotlib.axes.Axes.xaxis_inverted()函數:
範例1:
# Implementation of matplotlib function
import matplotlib.pyplot as plt
import numpy as np
fig, ax = plt.subplots()
ax.axvspan(1.5, 2.5, facecolor ='g', alpha = 0.7)
ax.invert_xaxis()
ax.set_title('matplotlib.axes.Axes.xaxis_inverted()\
Example\n',
fontsize = 14, fontweight ='bold')
x = ax.xaxis_inverted()
ans ="No"
if x:
ans ="Yes"
ax.text(2.2, 1.02, "X-axis is inverted ?:" + ans,
style ='italic', fontsize = 12)
plt.show()
輸出:
範例2:
# Implementation of matplotlib function
import matplotlib.pyplot as plt
import numpy as np
np.random.seed(19680801)
plt.rcdefaults()
fig, ax = plt.subplots()
people = ('Geek1', 'Geek2', 'Geek3',
'Geek4', 'Geek5')
y_pos = np.arange(len(people))
performance = 3 + 4.5 * np.random.rand(len(people))**2
error = np.random.rand(len(people))
ax.barh(y_pos, performance, xerr = error,
align ='center', color ="green")
ax.set_yticks(y_pos)
ax.set_yticklabels(people)
ax.invert_xaxis()
ax.set_xlabel('Performance')
x = ax.xaxis_inverted()
ans ="No"
if x:
ans ="Yes"
ax.set_title('matplotlib.axes.Axes.xaxis_inverted()\
Example\n',
fontsize = 14, fontweight ='bold')
ax.text(6, 4.75, "X-axis is inverted ?:" + ans,
style ='italic', fontsize = 12)
plt.show()
輸出:
