Introduction
Plotly for Rust is a straightforward plotting library that makes it easy to visualize data with minimal effort. Documentation and numerous interactive examples can be found in the Plotly.rs Book, the examples directory, and docs.rs.
Basic Usage
To begin using Plotly.rs, you will need to add it to your Cargo.toml file:
[dependencies]
plotly = "0.10.0"Exporting an Interactive Plot
You can save any figure as an HTML file using the Plot.write_html() method. This HTML file can be opened in any web browser for a fully interactive experience. Think of this method as a postman, delivering a beautiful plot right to your viewer’s doorstep.
use plotly::{Plot, Scatter};
let mut plot = Plot::new();
let trace = Scatter::new(vec![0, 1, 2], vec![2, 1, 0]);
plot.add_trace(trace);
plot.write_html("out.html");Exporting a Static Image
To save a plot as a static image, you need the kaleido feature:
[dependencies]
plotly = { version = "0.10.0", features = ["kaleido"] }With this feature, you can save plots as formats like PNG or JPEG. It’s like capturing a snapshot of your work!
use plotly::{ImageFormat, Plot};
let mut plot = Plot::new();
let trace = Scatter::new(vec![0, 1, 2], vec![2, 1, 0]);
plot.add_trace(trace);
plot.write_image("out.png", ImageFormat::PNG, 800, 600, 1.0);Usage Within a Wasm Environment
To enable Plotly.rs in a WebAssembly-based environment, you initiate it with:
[dependencies]
plotly = { version = "0.10.0", features = ["wasm"] }Then include the Plotly JavaScript library in your base HTML. This allows you to create plots in frontend frameworks like Yew. Imagine it as setting a stage for your plot character to perform!
