Python中的 Matplotlib.axes.Axes.set_yticklabels()
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.set_yticklabels()函数
matplotlib 库的 axes 模块中的Axes.set_yticklabels()函数用于设置带有字符串标签列表的 y-tick 标签。
Syntax: Axes.set_yticklabels(self, labels, fontdict=None, minor=False, **kwargs)
Parameters: This method accepts the following parameters.
- labels : This parameter is the list of of string labels.
- fontdict : This parameter is the dictionary controlling the appearance of the ticklabels.
- minor : This parameter is used whether set major ticks or to set minor ticks
Return value: This method returns a list of Text instances.
下面的示例说明了 matplotlib.axes 中的 matplotlib.axes.Axes.set_yticklabels()函数:
示例 1:
# Implementation of matplotlib function
import matplotlib.pyplot as plt
import matplotlib.transforms as mtransforms
fig, ax = plt.subplots()
ax.plot(range(12, 24), range(12))
ax.set_yticks((2, 5, 7, 10))
ax.set_yticklabels(("Label-1", "Label-2",
"Label-3", "Label-4"))
fig.suptitle('matplotlib.axes.Axes.set_yticklabels()\
function Example\n\n', fontweight ="bold")
fig.canvas.draw()
plt.show()
输出:
示例 2:
# Implementation of matplotlib function
import numpy as np
import matplotlib.pyplot as plt
# Fixing random state for reproducibility
np.random.seed(19680801)
x = np.linspace(0, 2 * np.pi, 100)
y = np.sin(x)
y2 = y + 0.2 * np.random.normal(size = x.shape)
fig, ax = plt.subplots()
ax.plot(x, y)
ax.plot(x, y2)
ax.set_yticks([-1, 0, 1])
ax.spines['left'].set_bounds(-1, 1)
ax.spines['right'].set_visible(False)
ax.spines['top'].set_visible(False)
ax.set_yticklabels(("Val-1", "Val-2", "Val-3"))
fig.suptitle('matplotlib.axes.Axes.set_yticklabels()\
function Example\n\n', fontweight ="bold")
fig.canvas.draw()
plt.show()
输出:
