Coloring issue with graph mouseover

-When hovering over the graph, there is a rectangle with circles on the right side. The color of the circles should match the corresponding Train Title on the left -- both the Train Title and the Circles should be in the same order.

For example:

This is probably a bug in CanvasJS. I'll have to investigate.
