pyplot选项卡字符 [英] pyplot tab character

问题描述

我正在尝试在 pyplot 中使用制表符.但是，制表符显示的是正方形，而不是我需要的制表符空间.

I am trying to use the tab character in pyplot. However, the tab character is displaying a square, not the tab space I require.

我的代码是:

fig = pl.figure()
fig.text(.1,.05, "test \t test", bbox=dict(facecolor='red', alpha=0.5))

有人知道为什么这不起作用吗?

Does anyone know why this doesn't work?

推荐答案

我很惊讶 pylab.show 实际上显示了一些空格来代替您的正方形.但是 savefig 并没有试图变得聪明并提供您所描述的内容.现在，一个制表符需要多少个空格?这个问题没有意义.是给你4吗?我会为我选择 4.2.这意味着您需要确定希望选项卡在文本中占据多少空格，即:

I was surprised that pylab.show actually shows some spaces in place of your square. But savefig does not try to be smart and gives what you describe. Now, how many spaces does one tab take ? This question makes no sense. Is it 4 for you ? I will pick 4.2 for me. This means you need to decide how many spaces you want a tab to take in your text, i.e.:

fig = pylab.figure()
text = "test \t test".replace("\t", "    ")
fig.text(.1,.05, text, bbox=dict(facecolor='red', alpha=0.5))

或者，也许您只是想使用标准"约定来扩展选项卡:

Or, maybe you want to simply expand your tabs using "standard" conventions:

text = "test \t test".expandtabs()
