Save in multiple formats

[LittleOneChewy]

Is it possible to save multiple outputs with the same data?

I'm using this code:

let plot_filename = format!("{}.svg", file_name);
let root = SVGBackend::new(&plot_filename, (1680, 1050)).into_drawing_area();
root.fill(&WHITE).unwrap();
let areas = root.split_by_breakpoints([1300], [1050]);
let mut chart = ChartBuilder::on(&areas[0])
    .caption("Timings Plot", ("sans-serif", 50).into_font())
    .margin(5)
    .x_label_area_size(30)
    .y_label_area_size(30)
    .build_cartesian_2d(0f64..max_time, 0f64..max_duration)
    .unwrap();
....

And then filling it. I want to save the output to PNG with the same data, but I don't want to copy the code using another instance of ChartBuilder.

Sorry if this question has already been answered - I couldn't find it.
