Python中的 Matplotlib.axes.Axes.get_title()
Matplotlib是Python中的一个库,它是 NumPy 库的数值数学扩展。 Axes 类包含大部分图形元素:Axis、Tick、Line2D、Text、Polygon 等,并设置坐标系。 Axes 的实例通过回调属性支持回调。
matplotlib.axes.Axes.get_title()函数
matplotlib 库的 axes 模块中的Axes.get_title()函数用于获取坐标轴标题。
Syntax: Axes.get_title(self, loc=’center’)
Parameters: This method accepts the following parameters.
- loc : This parameter is an optional parameter and it is used for Which title to get.
Return: This function return the title text string.
下面的示例说明了 matplotlib.axes 中的 matplotlib.axes.Axes.get_title()函数:
示例 1:
# Implementation of matplotlib function
import os
from matplotlib import font_manager as fm, rcParams
import matplotlib.pyplot as plt
fig, ax = plt.subplots()
fpath = os.path.join(rcParams["datapath"],
"fonts / ttf / cmr10.ttf")
prop = fm.FontProperties(fname = fpath)
fname = os.path.split(fpath)[1]
ax.set_title('Title with special font: {}'.format(fname),
fontproperties = prop, fontsize = 14)
w = ax.get_title()
ax.text(0.2, 0.6, "Previously assigned title : \n\n"+str(w),
fontsize = 14)
ax.set_title("matplotlib.axes.Axes.get_title() \
function Example\n", fontweight ="bold")
plt.show()
输出:
示例 2:
# Implementation of matplotlib function
import numpy as np
import matplotlib.pyplot as plt
x = np.arange(0.1, 5, 0.1)
y = np.exp(-x)
yerr = 0.1 + 0.1 * np.sqrt(x)
fig, (ax, ax1) = plt.subplots(nrows = 1,
ncols = 2,
sharex = True)
ax.errorbar(x, y, yerr = yerr, color ="green")
ax.set_title('Title of Axes 1', fontweight ="bold")
ax1.errorbar(x, y, yerr = yerr, errorevery = 5,
color ="green")
ax1.set_title('Title of Axes 2', fontweight ="bold")
w = ax.get_title()
ww = ax1.get_title()
ax.set_title("")
ax1.set_title("")
ax.set_xlabel(w)
ax1.set_xlabel(ww)
fig.suptitle("Previously assigned title of each Axes is\
used at labels\n", fontweight ="bold")
plt.show()
输出:
