/*! # Plotters - Another Plotting Library in Rust Plotters is a flexible drawing library for data visualization written in pure Rust. The library isn't aimed supporting different types of plotting, but a generic platform that can be extended to support different types of visualization methods. ## Quick Start ```rust use plotters::prelude::*; fn main() -> Result<(), Box<dyn std::error::Error>> { let mut backend = BitMapBackend::new("examples/outputs/0.png", (640,480)); backend.open()?; let root:DrawingArea<_,_> = backend.into(); let font = Into::<FontDesc>::into("DejaVu Serif").resize(20.0); root.fill(&RGBColor(255,255,255))?; let mut chart = ChartBuilder::on(&root) .caption("y=x^2", &font) .build_ranged::<RangedCoordf32, RangedCoordf32, _, _>(-1f32..1f32, 0f32..1f32); chart.configure_mesh() .draw()?; chart.draw_series(LineSeries::new( (-50..=50).map(|x| x as f32 / 50.0).map(|x| (x, x*x)), &RGBColor(255, 0, 0), ))?; root.close()?; return Ok(()); } ``` ![](https://raw.githubusercontent.com/38/plotters/master/examples/outputs/0.png) ## Concepts by examples ### Drawing Backends Plotters can use different drawing backends, such as SVG, BitMap, etc. And even real-time rendering, such as library. For example a bitmap drawing backend. ```rust use plotters::prelude::*; fn main() -> Result<(), Box<dyn std::error::Error>> { // Create a 800*600 bitmap and start drawing let mut backend = BitMapBackend::new("examples/outputs/1.png", (300,200)); // And if we want SVG backend // let backend = SVGBackend::new("output.svg", (800, 600)); backend.open()?; backend.draw_rect((50,50), (200, 150), &RGBColor(255,0,0), true)?; backend.close()?; return Ok(()); } ``` And this will produce ![](https://raw.githubusercontent.com/38/plotters/master/examples/outputs/1.png) ### Drawing Area Plotters use a concept called drawing area for layout purpose. Plotters support multiple plot integrate in a single image. This is done by craeting sub drawing areas. Besides that, drawing area also allows customized cooridnate system, by doing so, the coordinate mapping is done by the drawing area automatically. ```rust use plotters::prelude::*; fn main() -> Result<(), Box<dyn std::error::Error>> { let backend = BitMapBackend::new("examples/outputs/2.png", (300, 200)); // A backend object can be converted into a drawing area let root_drawing_area:DrawingArea<_,_> = backend.into(); // And we can split the drawing area into 3x3 grid let child_drawing_areas = root_drawing_area.split_evenly((3,3)); // Then we fill the drawing area with different color for (area,color) in child_drawing_areas.into_iter().zip(0..) { area.fill(&Plattle99::pick(color))?; } root_drawing_area.close()?; return Ok(()); } ``` And this will produce ![](https://raw.githubusercontent.com/38/plotters/master/examples/outputs/2.png) ### Elements In Plotters, elements are build blocks of a image. All elements are able to draw on a drawing area. There are different types of elements, such as, lines, texts, circles, etc. You may also combining existing elements to build a complex element. ```rust use plotters::prelude::*; fn main() -> Result<(), Box<dyn std::error::Error>> { let backend = BitMapBackend::new("examples/outputs/3.png", (300, 200)); // A backend object can be converted into a drawing area let root:DrawingArea<_,_> = backend.into(); // Draw an circle on the drawing area root.draw(&Circle::new((100,100), 50, Into::<ShapeStyle>::into(&RGBColor(255, 0, 0)).filled()))?; root.close()?; return Ok(()); } ``` And this will produce ![](https://raw.githubusercontent.com/38/plotters/master/examples/outputs/3.png) ### Composable Elements ### Plotting ## Extending Plotters */ pub mod chart; pub mod data; pub mod drawing; pub mod element; pub mod series; pub mod style; pub mod prelude { pub use crate::chart::{ChartBuilder, ChartContext}; pub use crate::drawing::coord::{ CoordTranslate, Ranged, RangedCoord, RangedCoordf32, RangedCoordf64, RangedCoordi32, RangedCoordi64, RangedCoordu32, RangedCoordu64, }; pub use crate::drawing::{backend::DrawingBackend, DrawingArea}; pub use crate::series::{LineSeries, PointSeries}; pub use crate::style::{ Color, FontDesc, Mixable, Plattle, Plattle100, Plattle99, Plattle9999, RGBColor, ShapeStyle, TextStyle, }; pub use crate::drawing::{BitMapBackend, SVGBackend}; pub use crate::element::{Circle, Cross, EmptyElement, OwnedText, Path, Rectangle, Text}; }
