Outline color for grid.

[bochoven]

Hi I wanted to change the outline color for the grid without also changing the color of the labels.

Specify with

grid: {
  outlineColor : '#EEEEEE'
}

Hi @bochoven, nice addition!

Please consider wrapping your code (in your post) with the following syntax:

```javascript
grid: {
  outlineColor : '#EEEEEE'
}

Which will render it like this:

``` javascript
grid: {
  outlineColor: '#EEEEEE'
}
