The default tick formatter#

By default, tick labels are formatted using a ScalarFormatter, which can be configured via ticklabel_format. This example illustrates some possible configurations:

  • Default.

  • useMathText=True: Fancy formatting of mathematical expressions.

  • useOffset=False: Do not use offset notation; see ScalarFormatter.set_useOffset.
