Struct PerCoreSparklineGrid 

pub struct PerCoreSparklineGrid {
    pub core_histories: Vec<Vec<f64>>,
    /* private fields */
}

Grid of sparklines showing per-core CPU history.

In condensed view, only the aggregate sparkline is shown. In exploded view, each core gets its own sparkline with 60-second history.

Fields

core_histories: Vec<Vec<f64>>

Per-core history buffers (each is 60 samples = 60 seconds at 1s refresh)

Implementations

impl PerCoreSparklineGrid

pub fn new(core_histories: Vec<Vec<f64>>) -> Self

Create a new per-core sparkline grid.

pub fn with_columns(self, cols: usize) -> Self

Set explicit column count.

pub fn with_gradient(self, gradient: Gradient) -> Self

Set custom gradient.

pub fn without_labels(self) -> Self

Disable core labels.

pub fn set_histories(&mut self, histories: Vec<Vec<f64>>)

Update core histories.
