\graphpaper ¶Synopsis:
\graphpaper(x_init,y_init)(x_dimen,y_dimen) \graphpaper[spacing](x_init,y_init)(x_dimen,y_dimen)
Draw a coordinate grid. Requires the graphpap package.
The grid’s origin is (x_init,y_init).
Grid lines come every spacing units (the default is 10).
The grid extends x_dimen units to the right and y_dimen units up.
