it's not like 14000 points.
I have seven rows in the datagrid with each row having a linechart in one
cell,and each line chart is to be plotted for 2000 values. problem comes only
when i use itemrenderer to display circles also.

7 rows of 2000 is 14000 points. That's quite a
bit. Do they all have to change at once?

i
figured out whats the cause of timeout error but not able to find a
solution.
in my itemrenderer for the datagrid i am
constructing linechart with a CircleItemRenderer and this takes lot of time .
If
i don't use any itemrenderer then it works fine, but i need a linechart with
points.
Is there anyway i can make circle after making
linechart?
// Add a
lineSeries
lineS = new
LineSeries() ;
lineS.setStyle( "lineStroke" ,lineStroke) ;
lineS.setStyle( "form","segment" );
lineS.setStyle( "itemRenderer" ,new
ClassFactory( CircleItemRender er));
lineS.yField = "data";
seriesArray. push(lineS) ;
lineChart.series = seriesArray;
for now my data
contains around 2000 values for each line chart and there are seven rows in the
datagrid and only one column with linechart in it's each cell.

Probably. You have to find out where all the time is
being spent and do some optimization.
How much data is a "large amount"? How many line and
bar charts are on screen? Do all of them need updating or can you stop
certain ones from updating? Can you break up the updates and just do one
pair of charts at a time?
You could take one of your line and bar charts and measure
how long it takes to update them with new data when outside of the DG, then
test
with only one pair in the DG. One way I do this is to put an "enterFrame"
listener on the stage and trace out the value of getTimer(). Normally,
you'll see the value increase by the frame-rate. Then when it gets busy
you'll see the value increase by much more and that gives you an idea of the
overhead.

charts and bar charts in it's columns.
Error: Error #1502: A script has

but is there any other way around ?
