Thanks Jeff for responding. Yes, the yField does not exist in the dataProvider itself but it does in the "parent" of the dataProvider. Is there no way to reference this? or can the dataProvider be specified in a different way? Is there a way to set the value to a constant in the <mx:PlotSeries> tag?
What do you mean by: "...add theyVal attribute to each item." ? One thing I CAN do is to convert the series into an ArrayCollection. I was just hoping to find a more elegant solution to the problem. --- In flexcoders@yahoogroups.com, "Battershall, Jeff" <[EMAIL PROTECTED]> wrote: > > I'm not sure how you're going to stipulate a yField that doesn't exist > in the dataprovider. > > If you have control over the XML format, add the additional attribute to > each datapoint item. > > If you don't, then you'll need to take what you're given and add the > yVal attribute to each item. > > Jeff > > -----Original Message----- > From: flexcoders@yahoogroups.com [mailto:[EMAIL PROTECTED] On > Behalf Of wreedijk > Sent: Friday, June 27, 2008 2:36 AM > To: flexcoders@yahoogroups.com > Subject: [flexcoders] Charting - setting yField property for a > PlotSeries when dataProvider is XML > > > I am trying to create a PlotChart with series (y is constant) from an > XML object that is defined as follows: > > <series yVal='Weight'> > <dataPoint date='12/01/2004'/> > <dataPoint date='12/25/2004'/> > <dataPoint date='1/1/2005'/> > <dataPoint date='1/22/2005'/> > </series> > > I want the xField to be derived from the date attribute in the dataPoint > - no problem.
