Python 中的 matplotlib . axis . axis . get _ sketch _ params()函数
原文:https://www . geeksforgeeks . org/matplotlib-axis-axis-get _ sketch _ params-python 中的函数/
Matplotlib 是 Python 中的一个库，是 NumPy 库的数值-数学扩展。这是一个神奇的 Python 可视化库，用于 2D 数组图，并用于处理更广泛的 SciPy 堆栈。
matplotlib . axis . axis . get _ sketch _ params()函数
matplotlib 库的 Axis 模块中的 Axis.get_sketch_params()函数用于获取艺术家的草图参数。
语法:axis . get _ sketch _ params(self)
参数:该方法不接受任何参数。
返回值:此方法返回艺术家的草图参数。
以下示例说明 matplotlib . axis . axis . get _ sketch _ params()函数在 matplotlib.axis: 中的作用
例 1:
Python 3
# Implementation of matplotlib function
from matplotlib.axis import Axis
import matplotlib.pyplot as plt
import matplotlib.colors as mcolors
import matplotlib.gridspec as gridspec
import numpy as np
plt.rcParams['savefig.facecolor'] = "0.8"
plt.rcParams['figure.figsize'] = 6, 5
fig, ax = plt.subplots()
ax.plot([1, 2])
ax.locator_params("x", nbins = 3)
ax.locator_params("y", nbins = 5)
ax.set_xlabel('x-label')
ax.set_ylabel('y-label')
ax.text(0.2, 1.8, "Sketch Parameters : "
+str(Axis.get_sketch_params(ax)),
fontweight ="bold")
fig.suptitle("""matplotlib.axis.Axis.get_sketch_params()
function Example\n""", fontweight ="bold")
plt.show()
