let mut bar_chart = BarChart::new_with_theme(
    vec![
        ("Evaporation", vec![2.0, 4.9, 7.0, 23.2, 25.6, 76.7, 135.6]).into(),
        (
            "Precipitation",
            vec![2.6, 5.9, 9.0, 26.4, 28.7, 70.7, 175.6],
        )
            .into(),
        ("Temperature", vec![2.0, 2.2, 3.3, 4.5, 6.3, 10.2, 20.3]).into(),
    ],
    vec![
        "Mon".to_string(),

bar_chart.legend_margin = Some(Box {
    top: bar_chart.title_height,
    bottom: 5.0,
    ..Default::default()
});
bar_chart.series_list[2].category = Some(SeriesCategory::Line);
bar_chart.series_list[2].y_axis_index = 1;
bar_chart.series_list[2].label_show = true;

bar_chart
    .y_axis_configs
    .push(bar_chart.y_axis_configs[0].clone());
bar_chart.y_axis_configs[0].axis_formatter = Some("{c} ml".to_string());
bar_chart.y_axis_configs[1].axis_formatter = Some("{c} °C".to_string());

println!("{}", &bar_chart.svg().unwrap());
svg_to_png(&bar_chart.svg().unwrap()).unwrap();
