Categorical view to text produces empty string #75
Description
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); }
