如何在matplotlib中显示所有标签值 [英] How to display all label values in matplotlib

问题描述

我有两个列表，当我使用以下代码绘图时，x 轴最多只显示 12(最大值为 15).我可以知道如何将 x 列表中的所有值显示到 x 轴上吗?提前致谢.

x = [4,5,6,7,8,9,10,11,12,13,14,15,0,1,2,3]y = [10,20,30,40,50,60,70,80,90,100,110,120,130,140,​​150,160]fig = plt.figure()ax1 = fig.add_subplot(111)ax1.plot(np.arange(len(x)), y, 'o')ax1.set_xticklabels(x)plt.show()

如果我在 set_xticklabels 函数中设置 minor=True，它会显示所有 x=2,4,6,8,..,16...但我想要所有值.

附言我的 x 轴未排序，应显示为所示.

解决方案

这里的问题是刻度数 - 自动设置 - 与绘图中的点数不同.

要解决此问题，请设置刻度数:

ax1.set_xticks(np.arange(len(x)))

在 ax1.set_xticklabels(x) 调用之前.

I have two lists, when I plot with the following code, the x axis only shows up to 12 (max is 15). May I know how can I show all of the values in x list to the x axis? Thanks in advance.

x = [4,5,6,7,8,9,10,11,12,13,14,15,0,1,2,3]
y = [10,20,30,40,50,60,70,80,90,100,110,120,130,140,150,160]
fig = plt.figure()
ax1 = fig.add_subplot(111)
ax1.plot(np.arange(len(x)), y, 'o')
ax1.set_xticklabels(x)
plt.show()

If I set minor=True in the set_xticklabels function, it shows me all x=2,4,6,8,..,16... but I want ALL values.

P.S. My x axis is not sorted, should display as it shows.

解决方案

The issue here is that the number of ticks -set automatically - isn’t the same as the number of points in your plot.

To resolve this, set the number of ticks:

ax1.set_xticks(np.arange(len(x)))

Before the ax1.set_xticklabels(x) call.
