        "\n# Major and minor ticks\n\nDemonstrate how to use major and minor tickers.\n\nThe two relevant classes are `.Locator`\\s and `.Formatter`\\s.  Locators\ndetermine where the ticks are, and formatters control the formatting of tick\nlabels.\n\nMinor ticks are off by default (using `.NullLocator` and `.NullFormatter`).\nMinor ticks can be turned on without labels by setting the minor locator.\nMinor tick labels can be turned on by setting the minor formatter.\n\n`.MultipleLocator` places ticks on multiples of some base.\n`.StrMethodFormatter` uses a format string (e.g., ``'{x:d}'`` or ``'{x:1.2f}'``\nor ``'{x:1.1f} cm'``) to format the tick labels (the variable in the format\nstring must be ``'x'``).  For a `.StrMethodFormatter`, the string can be passed\ndirectly to `.Axis.set_major_formatter` or\n`.Axis.set_minor_formatter`.  An appropriate `.StrMethodFormatter` will\nbe created and used automatically.\n\n`.pyplot.grid` changes the grid settings of the major ticks of the x- and\ny-axis together.  If you want to control the grid of the minor ticks for a\ngiven axis, use for example ::\n\n  ax.xaxis.grid(True, which='minor')\n\nNote that a given locator or formatter instance can only be used on a single\naxis (because the locator stores references to the axis data and view limits).\n"
