Enum DrawEvent

pub enum DrawEvent {
    AddPlot {
        id: SeriesGraphId,
        title: Option<String>,
    },
    UpdatePlot {
        id: SeriesGraphId,
        bar_index: usize,
        timestamp: i64,
        value: Option<f64>,
    },
}

A drawing event emitted during VM execution.

These events describe visual operations that occur as the script runs. In OutputMode::Stream mode, native functions emit DrawEvent variants instead of updating the Chart directly.

Variants

AddPlot

A new plot() series was registered (first bar only).

Fields

id: SeriesGraphId

The compile-time series graph id.

title: Option<String>

The plot title, if provided.

UpdatePlot

A plot() value was emitted for the current bar.

Fields

id: SeriesGraphId

The compile-time series graph id.

bar_index: usize

Zero-based bar index.

timestamp: i64

The bar’s epoch-millisecond timestamp.

value: Option<f64>

The plotted value (None means na).
