连续执行两次可以改变颜色但失去动画效果 或在changeData()后执行chart.repaint()

Start with the linked reproduction demo and trace the chart.changeData() update path, comparing it with the chart.repaint() behavior mentioned in the issue. Verify the case where line-point colors depend on changed data, including whether animation is preserved. Done means the colors update after one changeData() call without requiring repaint or a second call.
