You haven't told the CategoryAxis what its dataProvider is. In MXML the dataprovider is set implicitly in the chart definition. If you are adding line series programmatically, you need to add the CategoryAxis dataProvider programmatically as well.
Give the CategoryAxis an id... <mx:CategoryAxis id="ca" categoryField="loadval"/> then, in Actionscript, give it a dataProvider... ca.dataProvider = testdata; HTH Steve --- In [email protected], "Trefalgar Bain" <trefal...@...> wrote: > > I've got two charts, one is 99% mxml (the 1% is actionscript defining > the datasource definition), the other is mostly actionscript.
