Struct Chart

pub struct Chart { /* private fields */ }

Collection of visuals produced during script execution.

Access via Instance::chart() after executing bars. Contains two categories of visual outputs:

• Series graphs — per-bar data like plot(), bgcolor(), fill(), accessed via series_graphs().
• Non-series graphs — point-in-time objects like label.new(), line.new(), box.new(), table.new(), accessed via graphs().

Examples

let chart = instance.chart();

println!("Background: {:?}", chart.background_color());
println!("Bar count: {}", chart.series_len());

// Series graphs (plots, fills, bgcolor, etc.)
for (id, sg) in chart.series_graphs() {
    if let Some(plot) = sg.as_plot() {
        println!("Plot '{:?}': {} values", plot.title, plot.series.len());
    }
}

// Non-series graphs (labels, lines, boxes, tables, etc.)
for (id, g) in chart.graphs() {
    if let Some(line) = g.as_line() {
        println!(
            "Line from ({},{}) to ({},{})",
            line.x1, line.y1, line.x2, line.y2
        );
    }
}

Implementations

impl Chart

pub fn background_color(&self) -> Option<Color>

Returns the configured chart background color.

pub fn series_graphs( &self, ) -> impl Iterator<Item = (SeriesGraphId, &SeriesGraph)>

Iterates over all per-series graphs.

pub fn series_graph(&self, id: SeriesGraphId) -> Option<&SeriesGraph>

Returns the per-series graph for the given id.

pub fn graphs(&self) -> impl Iterator<Item = (GraphId, &Graph)>

Iterates over all non-series graphs.

pub fn graph(&self, id: GraphId) -> Option<&Graph>

Returns the graph for the given id.

pub fn series_len(&self) -> usize

Returns the number of bars in the chart series.

pub fn bar_colors(&self) -> &BarColors

Returns the bar color overrides for the chart.

pub fn filled_orders_on_bar(&self, bar_index: usize) -> &[FilledOrder]

Returns the list of filled orders on the given bar_index.

Each fill includes the signal/order id (e.g. entry or exit name), price, and signed quantity. Returns an empty slice if the bar has no fills.
