I'm trying to use checkbox series selection in the legend of a real time chart, but it seems each time the chart is updated the checkboxes are redrawn unchecked and then eventually populated with a check mark.  If it's a real time chart, updating quickly, you can't turn off a series as the checkmark always functionally appears unchecked.

Another bug?

When I run your demo I get the same issue.  The graph updating makes the checks in the checkbox 'disappear'.  It looks like the series are turned off even though they are not.
