Struct plotpy::Text

pub struct Text { /* fields omitted */ }

Creates text to be added to a plot

Example

// import
use plotpy::{Plot, Text};
use std::path::Path;

// directory to save figures
const OUT_DIR: &str = "/tmp/plotpy/doc_tests";

// configure and draw text
let mut text = Text::new();
text.set_color("#cd0000")
    .set_align_horizontal("center")
    .set_align_vertical("center")
    .set_fontsize(30.0)
    .set_rotation(45.0);
text.draw(0.0, 0.0, "Hello World!");

// add text to plot
let mut plot = Plot::new();
plot.add(&text)
    .set_range(-1.0, 1.0, -1.0, 1.0)
    .set_hide_axes(true);

// save figure
let path = Path::new(OUT_DIR).join("doc_text.svg");
plot.save(&path)?;
