Styling: left, right, and yAxis line color?

[oasjohn]

I'm able to set the color of the grid lines in the ticks definition, but I can't seem to set the vertical lines for the left/right of the grid as well as the vertical line for the yAxis scale. Any ideas? See the screenshot below where the vertical lines are dark grey while others are set to a color.

UPDATE: nevermind - I found the option but will leave here in case anyone else needs it.
On the scales, you need to set the grid: { borderColor: someColor }
