Python中的 Matplotlib.axes.Axes.set_xscale()
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_xscale()函数
matplotlib 库的 axes 模块中的Axes.set_xscale()函数用于设置 x 轴刻度。
Syntax: Axes.set_xscale(self, value, **kwargs)
Parameters: This method accepts the following parameters.
- value : This parameter is the axis scale type to apply.
- **kwargs: There are different keyword arguments which are accepted and its depend on the scale.
下面的示例说明了 matplotlib.axes 中的 matplotlib.axes.Axes.set_xscale()函数:
示例 1:
# Implementation of matplotlib function
import matplotlib.pyplot as plt
import numpy as np
from matplotlib.ticker import EngFormatter
val = np.random.RandomState(19680801)
xs = np.logspace(1, 9, 100)
ys = (0.8 + 4 * val.uniform(size = 100)) * np.log10(xs)**2
fig, ax0 = plt.subplots()
ax0.set_xscale('log')
formatter0 = EngFormatter(unit ='Hz')
ax0.xaxis.set_major_formatter(formatter0)
ax0.plot(xs, ys)
ax0.set_xlabel('Frequency')
fig.suptitle('matplotlib.axes.Axes.set_xscale() \
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
fig, ax4 = plt.subplots()
x = 10.0**np.linspace(0.0, 2.0, 15)
y = x**2.0
ax4.set_xscale("log", nonposx ='clip')
ax4.set_yscale("log", nonposy ='clip')
ax4.errorbar(x, y, xerr = 0.1 * x,
yerr = 2.0 + 1.75 * y,
color ="green")
ax4.set_ylim(bottom = 0.1)
fig.suptitle('matplotlib.axes.Axes.set_xscale()\
function Example\n', fontweight ="bold")
plt.show()
输出:
