Fields

positions: Vec<Vec2>

Pixel positions for each data point.

x_axis: AxisId

X axis ID used for this cache.

y_axis: AxisId

x_range: (f64, f64)

Data range that was used to compute these positions.

y_range: (f64, f64)

Y data range that was used to compute these positions.

data_count: usize

Number of data points when cache was built.
