Enum PickedDataRef 

pub enum PickedDataRef {
    Point {
        source_id: Option<String>,
        series_id: String,
        point_index: usize,
    },
    HistogramBin {
        source_id: Option<String>,

        series_id: String,
        x_index: usize,
        y_index: usize,
    },
    ContourLevel {
        source_id: Option<String>,
        series_id: String,
        level_index: usize,
        x_index: usize,
        y_index: usize,
    },
}

A renderer-independent reference to one selected data primitive.

These records deliberately carry provenance only. Coordinates, bin edges, matrix values, and contour values remain in the caller’s registered source columns / series configuration; the renderer never creates a CPU shadow of GPU-owned data just to remember a selection.

Variants

Point

Fields

source_id: Option<String>

series_id: String

point_index: usize

HistogramBin

Fields

source_id: Option<String>

series_id: String

bin_index: usize

MatrixCell

Fields

source_id: Option<String>

series_id: String

x_index: usize

Canonical x-axis cell/quad index, independent of matrix storage orientation.

y_index: usize

Canonical y-axis cell/quad index, independent of matrix storage orientation.

ContourLevel

Fields

source_id: Option<String>

series_id: String

level_index: usize

Index into ContourConfig.levels; the level value itself stays in the chart configuration SSoT.

x_index: usize

Canonical x/y sample-cell indices containing the hit. They identify the local piece without copying a reconstructed coordinate.

y_index: usize
