      Description

      When issuing the call to removeAllSeries, there is a performance issue when there are a lot of series.  During investigation, Qt engineer Corey Pendleton noted that an "emit" was being done after each series was removed, rather than one "emit" at the end after all series had been removed.  This causes the chart to be refreshed after each series is removed.  He recommended that we write a bug report for this issue.
