Enum DrawEvent 

pub enum DrawEvent {
    NewBar {
        bar_index: usize,
    },
    Series(SeriesEvent),
    Graph(GraphEvent),
    FilledOrder(FilledOrder),
}

A drawing event emitted during VM execution.

Wraps [SeriesEvent] (per-bar data like plot(), bgcolor()) and [GraphEvent] (point-in-time objects like label.new(), line.new()).

In OutputMode::Stream mode, native functions emit DrawEvent variants instead of updating the Chart directly.

Variants

NewBar

A new bar has started; signals ChartAccumulator to grow its internal series buffers.

Emitted in OutputMode::Stream mode at the start of every new bar (confirmed or realtime-new), before any Series events for that bar.

Fields

bar_index: usize

Zero-based index of the new bar.

Series(SeriesEvent)

A series-graph event (per-bar data).

Graph(GraphEvent)

A non-series graph event (point-in-time objects).

FilledOrder(FilledOrder)

A strategy order fill recorded on the chart.
