Show the zero axis

[alexchandel]

RustGnuplot is unable to display the zero axis on gnuplot. The gnuplot commands are set xzeroaxis and set yzeroaxis, given here.

That's done using the set_x_axis method. It doesn't show up in the documentation search due to a Rust bug: rust-lang/rust#11943.

Here's an example:

#![feature(globs)]
extern crate gnuplot;

use gnuplot::*;

fn main()
{
    let mut fg = Figure::new();

    let x = [-1i, 1];
    let y = [-3i, 4];

    fg.axes2d()
    .lines(x.iter(), y.iter(), [Caption("A line"), Color("black")])
    .set_x_axis(true, [])
    .set_y_axis(true, [])
    // Turn off the borders and move the ticks to the axes
    .set_x_ticks(Some((Auto, 0)), [OnAxis(true)], [])
    .set_y_ticks(Some((Auto, 0)), [OnAxis(true)], [])
    .set_border(true, [], []);

    fg.show();
}
