I have run into this same problem before and found two solutions. I prefer
the first method below.
1) Create a [Bindable] Array variable to push your Series objects into and
then use <mx:PlotChart id="investment_chart"
series="{myBindableArrayOfSeriesObjects}" />
2) Before pushing Series objects into the chart.series array, set
chart.series equal to a new Array instance. You can do this in a method
that is called when the view is created.
Either way, chart.series needs an array to push the series objects into.
Let me know if that works out for you.
