In the future, a latex installation may be the only external dependency. For rendering the fraction expression in the loop I use .format method. The command pdflatex is needed. The first two examples directly pass a str or function. What companies lose when they track worker productivity (Ep. Tick formatters can be set in one of two ways, either by passing a str or function to set_major_formatter or set_minor_formatter , or by creating an instance of one of the various Formatter classes and providing that to set_major_formatter or set_minor_formatter. ; Using MiKTeX with Computer Modern fonts, if you get odd *Agg and PNG results, go to MiKTeX/Options and update your format files To control such values, add placeholders (curly brackets {}) in the text, and run the values through the format method: Example.
