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.get_title()函數
matplotlib庫的axiss模塊中的Axes.get_title()函數用於獲取軸標題。
用法: Axes.get_title(self, loc=’center’)
參數:此方法接受以下參數。
- loc:此參數是可選參數,用於獲取哪個標題。
返回:此函數返回標題文本字符串。
以下示例說明了matplotlib.axes中的matplotlib.axes.Axes.get_title()函數:
範例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()
輸出:
範例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()
輸出:
