matplotlib是一个用于创建出版质量图表的桌面绘图包（主要是2D方面）。该项目是由John Hunter于2002年启动的，其目的是为Python构建一个MATLAB式的绘图接口。matplotlib和IPython社区进行合作，简化了从IPython shell（包括现在的Jupyter notebook）进行交互式绘图。matplotlib支持各种操作系统上许多不同的GUI后端，而且还能将图片导出为各种常见的矢量（vector）和光栅（raster）图：PDF、SVG、JPG、PNG、BMP、GIF等。除了几张，本书中的大部分图都是用它生成的。
Limits used as exponents -- how to write under the limit symbol without using \displaymath?
If one needs to write a limit as an exponent, one might have this dilemma: if you use \displaymath , "x to infinity" will be nicely printed under the lim symbol, but your exponent will be using the normal font and will appear very big on the page. If you take out the 如何在IQ Option平台中开始获利交易 \displaymath instruction, the exponent will use the small font, but now the part "x to infinity" is not a subscript to the "lim" symbol anymore, it just follows it. Trying to use any font size instructions with \displaystyle , or actually inside the math mode, does not seem to work for me! Does anybody know any trick to get around this?
This is the horrible expression I am fighting with (might be easier to make my point this way):
I can't get the last exponent to behave, because it contains the limit (it's the last exponent, the one for the number e ). If I take out the \displaystyle , the limit gets messed up, as explained above.
