Struct Transform

pub struct Transform {
    pub pitch: f64,
    pub yaw: f64,
    pub scale: f64,
    pub x: i32,
    pub y: i32,
}

Transformations to be applied to your chart. Is modified by user input(if the mouse is enabled) and used by Chart::draw() and your builder callback.

Chart::draw() applies the scale and the x/y offset to your plot, so unless you want to create some effects on your own you don’t need to worry about them.

If you are creating a 3d plot however you will have to manually apply the pitch and yaw to your chart with the following code:

chart.with_projection(|mut pb| {
    pb.yaw = transform.yaw;
    pb.pitch = transform.pitch;
    pb.scale = 0.7; // Set scale to 0.7 to avoid artifacts caused by plotter's renderer
    pb.into_matrix()
});

Fields

pitch: f64

Pitch of your graph in 3d

yaw: f64

Yaw of your graph in 3d

scale: f64

Scale of your graph. Applied in Chart::draw()

x: i32

X offset of your graph. Applied in Chart::draw()

y: i32

Y offset of your graph. Applied in Chart::draw()
