I'm having a somewhat similar problem... I'm using a ViewStack that is linked to a chart derived from the zinger chart example. When you click on the chart, it changes the ViewStack to the canvas I want, and is supposed to modify the .text for a Label using the getDrillDownData(event.hitData.element.yField, event.hitData.item); that they provide.
The first time you click on the bars, the label text for both of these events is presented as "undefined". On the second and subsequent clicks, the labels are updated as expected. I'm no Flex or ActionScript expert, so I'm not sure if this is an error with Flex or (more likely) a problem with my code. I'm playing with .dispatchEvent to see if that will initialize things for me. --- In [email protected], "cnewroth55" <[EMAIL PROTECTED]> wrote: > > okay, I am trying to follow the zingerChart Example from MM Flex dev > site and have created my own columnCHart, what I want to do is to pass > the mouseClickData to my webservice, specificaly the field > 'displaygrd' so that the CFC can use this as an argument to get > employess out of DB I am not sure how to pass that data up to the > correct spot. > when I click a data column i get this error: > "Array of input arguments did not contain a required parameter at > position 2" > > Here is my code: > can anyone help? > > <mx:WebService > wsdl="http://127.0.0.1:8300/components/getdata.cfc?wsdl"; > id="getCountGrade1s"> > <mx:operation name="getEmployees"> > <mx:request> > <GRADCE1CNT></GRADCE1CNT> > <DISPLAYGRD></DISPLAYGRD> > </mx:request> > </mx:operation> > <mx:operation name="getGrade1s" > > <mx:request></mx:request> > </mx:operation> > </mx:WebService> > <mx:Panel title="Active Grades for D350" width="40%" height="50%" > xmlns:mx="http://www.macromedia.com/2003/mxml"; > > <mx:ColumnChart id="showpe" > dataProvider="{getCountGrade1s.getGrade1s.result}" showDataTips="true" > columnWidthRatio=".9" > mouseClickData="getCountGrade1s.getEmployees(event.hitData.element.yField, > event.hitData.item).send()" > > <mx:horizontalAxis> > <mx:CategoryAxis > dataProvider="{getCountGrade1s.getGrade1s.result}" > categoryField="DISPLAYGRD" /> > </mx:horizontalAxis> > <mx:verticalAxis> > <mx:LinearAxis name="Active" /> > </mx:verticalAxis> > <mx:series> > <mx:Array> > <mx:ColumnSeries name="Grade(s)" yField="GRADE1CNT" > > <mx:fill> > <mx:LinearGradient angle="0"> > <mx:entries> > <mx:Array> > <mx:GradientEntry ratio="30" > color="#258BC8" /> > <mx:GradientEntry ratio="80" > color="#82C9EB" /> > <mx:GradientEntry ratio="100" > color="#258BC8" /> > </mx:Array> > </mx:entries> > </mx:LinearGradient> > </mx:fill> > </mx:ColumnSeries> > </mx:Array> > </mx:series> > </mx:ColumnChart> Yahoo!
