DEVELOPER WORKS

I'm creating a Radar Chart and would like to Show the Data Effects. How can I do it when I create the chart in ActionScript. Here's some code I got help with a few months back. Can someone help with the "showDataEffect"?
private function createLineSeries(xds:XML):
void
{ var s:RadarLineSeries; var dataSource:ArrayCollection; lineSeries = [];
for each (var x:XML in xds.series)
{ dataSource =
new ArrayCollection(); var o:Object=
new Object(); s =
new RadarLineSeries(); s.dataField =
"total"; s.categoryField =
"fullDate"; s.displayName = x.#name;
//s.showDataEffect="interpolate"; s.setStyle(
'stroke',
new Stroke(0xaaaaaa, 0, 0.7));
for each (var c:XML in x.item)
{ o =
{name:x.#name, total:c.#total.toString(), month:c.#month, year:c.#year, fullDate:c.#fullDate
}; dataSource.addItem(o);
} RadarLineSeries(s).setStyle(
'itemRenderer',
new ClassFactory(CircleItemRenderer)); RadarLineSeries(s).setStyle(
'radius', 4); s.dataProvider = dataSource; lineSeries.push(s);
}
}

Hi,
Radar effects are documented here: http://publib.boulder.ibm.com/infocenter/elixent/v3r0/index.jsp?topic=%2Fcom.ibm.ilog.elixir.doc%2FContent%2FVisualization%2FDocumentation%2FFlex%2FElixir_Enterprise%2F_pubskel%2Fps_elixir_corecomponents204.html
Hope this helps,

When I try add the effect with setStyle (RadarLineSeries(s).setStyle('showDataEffect', ip);) I get this error:
TypeError: Error #1009: Cannot access a property or method of a null object reference.
private function createColumnSeries(xds:XML):
void
{ var s:RadarColumnSeries; var dataSource:ArrayCollection; columnSeries = [];
for each (var x:XML in xds.series)
{ dataSource =
new ArrayCollection(); var o:Object=
new Object(); s =
new RadarColumnSeries(); s.dataField =
"total"; s.categoryField =
"fullDate"; s.displayName = x.#name;
for each (var c:XML in x.item)
{ o =
{name:x.#name, total:c.#total.toString(), month:c.#month, year:c.#year, fullDate:c.#fullDate
}; dataSource.addItem(o);
} RadarColumnSeries(s).columnWidthRatio = 0.80; RadarColumnSeries(s).setStyle(
'showDataEffect', ip); s.dataProvider = dataSource; columnSeries.push(s);
}
} <mx:SeriesInterpolate id=
"ip" duration=
"2000" offset=

Hi,
Could you provide a minimal, runnable sample to reproduce your problem?
Thanks,
Damien

Thanks Damien I certainly will do that as soon as I have a little time. It's just a minor request from the client in a long list of more pressing things that need to come first. And on that note I have to ask one last question. When using the columns in the Radar the user needs to over at the end of each column to display that data. Is it possible to make the entire column a hot spot for hovering the cursor to show each dataTip?
Thanks,
Mark

Hi Mark,
Which data points receive a data tip is defined by the findDataPoints() method of the serie. So to customize the behavior for a radar column series you have to create a custom class that extends RadarColumnSeries and overrides the findDataPoints(x:Number, y:Number, sensitivity:Number):Array /* of HitData */ method. Basically the method:
looks up the renderData.filteredCache array of ColumnSeriesItem to determine which item(s) correspond to the specified coordinates and sensitivity
creates an HitData per item
returns an array with the HitData.
Note that the findDataPoints() method and related classes are all part of the base Adobe's Flex Chart framework. So I encourage you to have a look at the sources of in this framework for hints on how to implement the method.
Let us know if you need more help implementing this.
Hope this helps,
Frédéric
