Struct ChartHandle 

pub struct ChartHandle {
    pub commands: Signal<Vec<ChartCommand>>,
}

A handle to a chart.

The handle is what an application keeps when the chart itself has to live somewhere else — in a component, in a closure, in a callback. The commands it carries travel through a signal, so the chart picks them up on its next frame, and an application that holds nothing but a signal can still drive a chart.

The handle is a copy: every copy talks to the same chart.

Fields

commands: Signal<Vec<ChartCommand>>

The commands waiting for the chart.

Implementations

impl ChartHandle

Inherent implementation of ChartHandle.

pub fn push(&self, command: ChartCommand) -> &Self

Sends a command to the chart.

The chart performs the command on its next frame.

Arguments

• ChartCommand - A ChartCommand parameter.

Returns

• &Self - The &Self value.

pub fn set_option(&self, option: ChartOption) -> &Self

Sends an option to the chart.

The chart draws the option on its next frame.

Arguments

• ChartOption - A ChartOption parameter.

Returns

• &Self - The &Self value.

pub fn resize(&self, width: f64, height: f64) -> &Self

Resizes the chart, in CSS pixels.

The chart draws at the new size on its next frame.

Arguments

• f64 - A 64-bit float (f64).

Returns

• &Self - The &Self value.

pub fn dispatch_action(&self, action: ChartAction) -> &Self

Performs an action on the chart.

The chart performs the action on its next frame.

Arguments

• ChartAction - A ChartAction parameter.

Returns

• &Self - The &Self value.

pub fn pending(&self) -> usize

Returns the number of commands waiting for the chart.

Returns

• usize - A non-negative integer.
