xForIndex method

double xForIndex(
  1. int index
)

The pixel x of column index. A single column is centered; otherwise columns span the full plot width with count - 1 equal gaps.

Implementation

double xForIndex(int index) {
  if (count <= 1) return bounds.left + bounds.width / 2;
  return bounds.left + bounds.width * index / (count - 1);
}
