Python中的 Matplotlib.axis.Tick.set_label()函数
Matplotlib是Python中的一个库,它是 NumPy 库的数值数学扩展。它是Python中用于二维数组图的惊人可视化库,用于处理更广泛的 SciPy 堆栈。
Matplotlib.axis.Tick.set_label()函数
matplotlib 库的axis 模块中的Tick.set_label()函数用于设置将在图例中显示的标签。
Syntax: Tick.set_label(self, a)
Parameters: This method accepts the following parameters.
- a: This parameter is converted to a string by calling str.
Return value: This method does not return any value.
下面的示例说明了 matplotlib.axis 中的 matplotlib.axis.Tick.set_label()函数:
示例 1:
Python3
# Implementation of matplotlib function
from matplotlib.axis import Tick
import matplotlib.pyplot as plt
import numpy as np
from matplotlib.collections import EllipseCollection
x = np.arange(5)
y = np.arange(7)
X, Y = np.meshgrid(x**2, y**3)
XY = np.column_stack((X.ravel(), Y.ravel()))
fig, ax = plt.subplots()
ec = EllipseCollection(5, 7, 5, units ='y',
offsets = XY * 0.5,
transOffset = ax.transData,
cmap ="plasma")
ec.set_array((X * Y + X * X).ravel())
ax.add_collection(ec)
ax.autoscale_view()
ax.set_xlabel('X')
ax.set_ylabel('y')
cbar = plt.colorbar(ec)
cbar.set_label('X + Y')
fig.suptitle('matplotlib.axis.Tick.set_label() \
function Example', fontweight ="bold")
plt.show()
Python3
# Implementation of matplotlib function
from matplotlib.axis import Tick
import matplotlib.pyplot as plt
import numpy as np
np.random.seed(19680801)
n = 100000
x = np.random.standard_normal(n)
y = 2 * np.random.standard_normal(n)
z =[1, 2, 3, 4]
fig, ax = plt.subplots()
hb = ax.hexbin(x, y,
gridsize = 50,
bins ='log',
cmap ='inferno')
cb = fig.colorbar(hb, ax = ax)
cb.set_label('log')
fig.suptitle('matplotlib.axis.Tick.set_label() \
function Example', fontweight ="bold")
plt.show()
输出:
