I have a table with a cell in each row containing a chart. There are about 10 charts, each with ~48 hours/data points. In firefox it renders in roughly ~5 seconds. In IE it sometimes takes over a
minute. The non-responsive script dialog appears once or twice. When running profiler from the debugger tools in IE, the majority of time ~40,000 - 60,000 milliseconds is spent between positionLabel()
and updateMaxLabelSize().
