"""
Use ``theme()`` to modify individual components of a theme,
allowing you to control all non-data components of the plot.
See also the `Plot Layout Diagrams <https://lets-plot.org/python/pages/charts.html#plot-layout-diagrams>`__ section.
Parameters
----------
exponent_format : {'e', 'pow', 'pow_full'} or tuple, default='pow'
Controls the appearance of numbers formatted with 'e' or 'g' types.
Value is either a string - style, or a tuple: (style, lower_exp_bound, upper_exp_bound)
where style can be:
- 'e' : e-notation (e.g., 1e+6)
- 'pow' : superscript powers of 10 in shortened form (e.g., 10^6)
- 'pow_full' : superscript powers of 10 with coefficient (e.g., 1×10^6)
For 'g' type formatting, scientific notation is applied when the number's exponent
is less than or equal to the lower_exp_bound (-7 by default) or greater than or equal
to the upper_exp_bound (6 by default, but can be affected by ``precision`` in format specifier).
See `Formatting <https://lets-plot.org/python/pages/formats.html>`__.
