View Full Version : line char performance issues

19 Sep 2010, 6:00 PM
i'm playing with line charts in EXTJS3.2.1 in IE7.
and the version of swf is 2.8.0

but it's very slow for me to show about 4-5 charts which just has 2-3 lines each.
and the amount of the data for every charts is less than 30 records.

it takes about 10 seconds to show all the charts. i have no idea about how to improve the performance.

the below is the source code,
take it easy , that's not virnus.
