问题描述
我需要在绘图的轴标签中键入希腊字母和Angstrom符号.例如
I need to type Greek letters and the Angstrom symbol in labels of axes in a plot. So for example
fig.gca().set_xlabel("$wavelength\, (Angstrom)$")
fig.gca().set_ylabel("$lambda$")
除了我实际上希望将"Angstrom"和"lambda"替换为实际的符号.我应该怎么做?谢谢！
except that I actually want "Angstrom" and "lambda" replaced by actual symbols. How should I do this? Thanks!
推荐答案
不仅可以将原始字符串添加到matplotlib，还可以使用以下方法在matplotlibrc或本地指定字体:
Not only can you add raw strings to matplotlib but you can also specify the font in matplotlibrc or locally with:
from matplotlib import rc
rc('font', **{'family':'serif','serif':['Palatino']})
rc('text', usetex=True)
这将更改您的衬线乳胶字体.您也可以像这样指定Sans-serif Helvetica
This would change your serif latex font. You can also specify the sans-serif Helvetica like so
rc('font',**{'family':'sans-serif','sans-serif':['Helvetica']})
其他选项是cursive和monospace以及它们各自的字体名称.您的标签将是
Other options are cursive and monospace with their respective font names.Your label would then be
fig.gca().set_xlabel(r'wavelength $5000 \AA$')
如果字体不提供Angstrom符号，则可以尝试使用\mathring{A}
If the font doesn't supply an Angstrom symbol you can try using \mathring{A}
