Add a data series dynamically in charts

Question

I am trying to add a data series dynamically in a chart but
it does not seems to work. Here is the sample code. Any idea?
var line1:LineSeries=new LineSeries();
line1.dataProvider=[something];
line1.displayName="New data";
chart.secondSeries.push(line1);
It works if I do the following but I don't want to remove
other series already there.
var arr = new Array();
chart.secondSeries=arr;
var line1:LineSeries=new LineSeries();
line1.dataProvider=[something];
line1.displayName="New data";
arr.push(line1);

I see...i don't know why the chart is not refreshing itself
in the next keyframe after you added another series. You can also
try to put the statement:
[myChart.series[(myChart.series as Array).length] = your new
ColumnSeries object goes here.]
in a new frame by doing doLater();
Apparently an asigninment statement on the series array does
the trick. If you don't like that approach, you can also try to
invalidate the display object, so that a refresh is forced.
