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);
}

looks like it has not been implemented yet
