隐藏matplotlib中的原点(x和y轴上为0) [英] Hide the origin (0 on x and y axis) in matplotlib

问题描述

我正在编写一些代码，我想隐藏图形中的原点(x 轴上的零和 y 轴上的零).我已经尝试了我见过的所有可能性，但是当我获得标签列表时，它们返回空，或者当范围为时，它们仅返回几个值(-2、-1、0、1、2、3)-10 - 10.

I'm working on some code and I'd like to hide the origin (the zero on the x-axis, and the zero on the y-axis) from the graph. I've tried all possibilities I've seen, but when I get the list of labels they return empty, or they return with only a few values (-2, -1, 0, 1, 2, 3) when the range is -10 - 10.

还可以将刻度线本身的字体更改为Computer Modern 10(LaTeX字体吗?)

Also, is there any way to change the font of the ticks themselves to Computer Modern 10 (The LaTeX font?)

推荐答案

可以使用 FuncFormatter 将 0 隐藏在轴上.此格式化程序的函数只需检查标签是否为0，并在这种情况下返回一个空字符串即可.

Hiding the 0 on the axes could be done using a FuncFormatter. The function for this formatter would simply check if the label is 0 and return an empty string in that case.

import matplotlib.pyplot as plt
import matplotlib.ticker as ticker
import numpy as np

x = np.linspace(-5,8)
y = np.sin(x)
plt.plot(x,y)

func = lambda x, pos: "" if np.isclose(x,0) else x
plt.gca().xaxis.set_major_formatter(ticker.FuncFormatter(func))
plt.gca().yaxis.set_major_formatter(ticker.FuncFormatter(func))

plt.show()
