Struct plotpy::Text

pub struct Text { /* private fields */ }

Creates text to be added to a plot

Example

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

fn main() -> Result<(), StrError> {
    // configure text
    let mut text = Text::new();
    text.set_color("purple")
        .set_align_horizontal("center")
        .set_align_vertical("center")
        .set_fontsize(30.0)
        .set_rotation(45.0)
        .set_bbox(true)
        .set_bbox_facecolor("pink")
        .set_bbox_edgecolor("black")
        .set_bbox_alpha(0.3)
        .set_bbox_style("roundtooth,pad=0.3,tooth_size=0.2");

    // draw text
    text.draw_3d(0.5, 0.5, 0.5, "Hello World!");

    // add text to plot
    let mut plot = Plot::new();
    plot.add(&text);

    // save figure
    plot.save("/tmp/plotpy/doc_tests/doc_text.svg")?;
    Ok(())
}
