Macro plot 

macro_rules! plot {
    (
        $( $( $variable:ident )? $( ( $x:ident, $y:ident ) )? $( as $name:literal )? ),* $(,)?
        $( where $($key:ident = $value:expr),* $(,)? )?
    ) => { ... };
}

This macro is used to quickly generate plots for a list of variables. All types that implement num_traits::cast::ToPrimitive can be plotted.

The macro takes a list of variables. By default, the value of the variable is mapped to the y axis, and the x axis shows the iteration number.

debug_plotter::plot!(a, b, c);

It is possible to pass a tuple if you want the x axis to be another value instead of the iteration number.

debug_plotter::plot!((x, a), (x, b), (x, c));

It is also possible to rename variables in the legend using the keyword as.

debug_plotter::plot!(a as "Alice", b as "Bob", c as "Charlie");

It is possible to provide additional options for the plot after a where keyword.

debug_plotter::plot!(a, b, c where caption = "My Caption");

The following table lists all available options.

Identifier	Example Value	Description
caption	"caption"	Sets the caption of the plot.
size	(400, 300)	Sets the size of the resulting image.
x_desc	"x description"	Sets the description of the x axis.
y_desc	"y description"	Sets the description of the y axis.
path	"/plots/my_plot.jpg"	Defines where the plot is saved.
x_range	0f64..100f64	Defines start and end of the x axis.
y_range	0f64..100f64	Defines start and end of the y axis.
