Categorical view to text produces empty string

[vlashada]

I get no text output when trying to convert a categorical view to text. When writing to svg, like barchart example, I see them, but when trying to convert to text, the output is empty.

use plotlib::{
repr::BarChart,
style::BoxStyle,
view::{CategoricalView, View},
};

fn main() {
    let b1 = BarChart::new(5.3).label("1");
    let b2 = BarChart::new(2.6)
        .label("2")
        .style(&BoxStyle::new().fill("darkolivegreen"));

    let v = CategoricalView::new()
        .add(b1)
        .add(b2)
        .x_label("Experiment")
        .to_text(20, 20)
        .unwrap();

    println!("{:?}", v);let v = CategoricalView::new()
        .add(b1)
        .add(b2)
        .x_label("Experiment")
        .to_text(20, 20)
        .unwrap();

    println!("{:?}", v);
}
