* - underline - boolean
*
*
* - border - An object defining the border style around the chart. The chart itself will decrease in dimensions to accomodate the border.

*
* - display - location of the legend. Possible values are "none", "left", "right", "top", and "bottom".
* - spacing - an image URL. May be relative to the current document or absolute.
* - padding, border, background, font - same options as described above.
*
* - dataTip - An object defining the style of the data tip (tooltip).
*
* - padding, border, background, font - same options as described above.
*
* - xAxis and yAxis - An object defining the style of the style of either axis.
*
* - color - same option as described above.
* - size - same option as described above.
* - showLabels - boolean
