Python 中的 matplotlib.axes.axes.get_sketch_params()

原文:https://www.geeksforgeeks.org/matplotlib-axes-axes-get_sketch_params-in-python/

Matplotlib 是 Python 中的一个库，是 NumPy 库的数值-数学扩展。轴类包含了大部分的图形元素:轴、刻度、线二维、文本、多边形等。，并设置坐标系。Axes 的实例通过回调属性支持回调。

matplotlib.axes.axes.get_sketch_params()函数

matplotlib 库的 Axes 模块中的 Axes.get_sketch_params()函数用于获取艺术家的草图参数。

语法: Axes.get_sketch_params(self)

参数:该方法不接受任何参数。

返回:此方法返回艺术家的草图参数。

下面的例子说明了 matplotlib.axes.axes.get_sketch_params()函数在 matplotlib.axes 中的作用:

例 1:

# Implementation of matplotlib function
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(ax.get_sketch_params()), 
        fontweight ="bold")

fig.suptitle('matplotlib.axes.Axes.get_sketch_params() \
function Example\n\n', fontweight ="bold")

plt.show()

输出:

例 2:

# Implementation of matplotlib function
import matplotlib.pyplot as plt
import numpy as np

values = np.array([
    0.015, 0.166, 0.133,
    0.159, 0.041, 0.024,

    0.010, 0.061, 0.008])

values[[3, 14]] += .8

ax.plot(values, "o-", color ="green")
ax2.plot(values, "o-", color ="green")

ax.set_ylim(.78, 1.) 
ax2.set_ylim(0, .22)

ax.spines['bottom'].set_visible(False)
ax2.spines['top'].set_visible(False)

ax.xaxis.tick_top()
ax.tick_params(labeltop = False)
ax2.xaxis.tick_bottom()

d = .005

kwargs.update(transform = ax2.transAxes)  
ax2.plot((-d, +d), (1 - d, 1 + d), **kwargs)
ax2.plot((1 - d, 1 + d), (1 - d, 1 + d), **kwargs) 

ax.set_sketch_params(1.0, 100.0, 22.0)
ax2.set_sketch_params(1.0, 100.0, 22.0)  

ax.text(5, .95, "Sketch Parameters : "
        +str(ax.get_sketch_params()), 
        fontweight ="bold")

fig.suptitle('matplotlib.axes.Axes.get_sketch_params() \
function Example\n\n', fontweight ="bold")

plt.show()
