[Ovmsdev] Highcharts help

[Michael Balzer]

Derek,

from your code snippet you've defined "chargechart", but try to access
"chargeChart" later on.

Also $(…).chart() does not return a Highcharts object, but the jQuery
DOM object collection passed to it (for chaining).

The correct way to get a reference to the actual Highcharts object is
using/remembering "this" in the load event, that is pointing to the
Highcharts instance.

Regards,
Michael
