Description

Hi,

when using PointSeries with some thausands of entries Firefox V29/V30 (under linux) slows down and for about 1-5 seconds is at 100% CPU usage. Within this time firefox does not react on any input mouse/keyboard, even the menu bar does not work.

Attached you will find a TestApp which creates a WCartesianChart with around 6000 entries. Using this chart with LineSeries the response time of Firefox is ok!

With Google Chrome PointSeries has also a good response time!

I have implemented a zoom function by using the mouse wheel of the chart will easily show the problem!

Regards,

Stefan
