66 line series with 218 plot points each for a total of 14388 plot points, if
we're looking for specifics. It's a lot of data that doesn't look particularly
good because of the sheer volume, but it's what they want.
I'm using a line chart. Using AMF3 to retrieve the data. The time it takes to
query the data, or transmit the data, isn't an issue. Also, the problem doesn't
happen over time, it could be the first request someone makes on the
application - I don't believe it's a memory leak.
The method used to populate the graph is thus:
var ls:LineSeries = new LineSeries();
ls.dataProvider = data[o];
ls.yField = "counter";
ls.xField = "dtime";
ls.displayName = o.valueOf();
if ( circleplots.selected ) {
ls.setStyle('itemRenderer', new ClassFactory(CircleItemRenderer));
}
var currentSeries:Array = linechart1.series;
currentSeries.push(ls);
linechart1.series = currentSeries;
Storing the data in an internal array, and possibly sending it to the clip
board isn't a big issue. It's trying to display that much data within a flex
construct that causes the problem(s).
