A conrod widget for displaying data in real time

Conrod Graph

conrod_graph is a collection of widgets for conrod that ease the creation of graphs. It was inspired by the Qt Custom Plot library.

How to use

At the moment, conrod_graph only supports drawing line graphs. The graph accepts a Fn(f64) -> f64.

fn set_ui(ref mut ui: conrod::UiCell, ids: &Ids) {
    use conrod::{widget, Positionable, Sizeable, Widget};
    use conrod_graph::LineGraph;

    // Set up canvas
    widget::Canvas::new()
        .set(ids.canvas, ui);

    // Creature a graph from x: [-1.0, 1.0] and y: [-1.0, 1.0]
    LineGraph::new(-1.0, 1.0, -1.0, 1.0)
      .add_line(Box::new(|x| f64::sin((x + 1.0)*std::f64::consts::PI)))
      .parent(ids.canvas)
      .middle()
      .wh_of(ids.canvas)
      .set(ids.graph, ui);
}

conrod_graph's Issues

Guide to running example needed

A guide to how to build and run the example would be useful in the readme.

EDIT: I managed to get the example to compile, but I get this error when compiling:

thread 'main' panicked at 'called `Result::unwrap()` on an `Err` value: "GL context creation failed"', ../src/libcore/result.rs:788
note: Run with `RUST_BACKTRACE=1` for a backtrace.

With some looking around, this issue servo/servo#9585 appears to be similar. it appears that my computer does not have a new enough OpenGL driver to be able to run Glutin. :(
