this works except for the only positive value:

Any ideas?

[flexcoders] Re: Negative plane in Column Chart
I have the same problem, i'm only using a chart with ColumnSets, it
always render fine except whith one negative value.
I wrote this example for explain:
?xml version=1.0 encoding=utf-8?
mx:Application xmlns:mx=http://www.adobe.com/2006/mxml;
layout=vertical
mx:Script
![CDATA[
import mx.collections.ArrayCollection;

{x: 1, a: 100, b: 20, c: 40},
{x: 2, a: 90, b: 30, c: 10},
{x: 3, a: 120, b: -50, c: 40},
{x: 4, a: 200, b: 100, c: 60},
{x: 5, a: 70, b: 45, c: 30}]);
]]
/mx:Script
mx:CartesianChart id=chart width=100% height=100%
dataProvider={dp}
mx:series

mx:ColumnSeries yField=b /
mx:ColumnSeries yField=c /
/mx:ColumnSet
/mx:series
mx:horizontalAxis
mx:CategoryAxis categoryField=x /
/mx:horizontalAxis
/mx:CartesianChart
/mx:Application
the object: {x: 3, a: 120, b: -50, c: 40} only render the a value...

Thanks guys for your fast replies. I have no that code right now,
but the
problem was that:
I use ColumnSet as the only element in ColumnChart and it has no yField
property of course(but there are yFields in ColumnSeries in
ColumnSet). I
don't understand very much how this component(ColumnChart) works
with it's
dataProvider, because it doesn't display negative values in that
situation
(only ColumnSet in the ColumnChart). But when I add another (invisible)
ColumnSeries with empty dataProvider in my ColumnChart, it began to
display
negative values for that ColumnSet. This problem description is rather
messy, I am sorry :) Is there are any thoughts about such a behavior?
2007/2/22, Ely Greenfield [EMAIL PROTECTED]:
Hi Mikhail. Can you be more specific about what you're looking
for? In
general, the charts support negative values with no problems, so
maybe I'm
not understanding your question.
Ely.

How to implement such a thing?
Simple defining negative values doesn't help. These columns just not
displayed.
If this is impossible within Column Chart, could you please advise me
where should I look for?
Thanks.

[flexcoders] Re: Custom DataGridColumn Component?
I have some problems with the component, i put it ina a datagrid and the
datagrid in another component, and in the line :
if(this.dataProvider[i][labelField] ==
parentDocument.dataProvider[parentDocument.selectedIndex][outerDocument.\
dataField])
i was trying to access to a field dataProvider but in the another
component, not the datagrid, so i try to access the datagrid's
dataprovider by outerDocument.owner.dataProvider and then with
outerDocument.[owner].dataProvider, and the same but it doesnt work,
thats very weird because in the flex debugger appears the property, so
finally, se solution var to add a property to the custom component to
make a reference to the datagrid:

}
}
this.selectedIndex = (index == -1) ? 0 :
index;
}
public function get selectTest():String{
return
this.selectedItem[outerDocument.returnField];
}
]]

if you are receiving a null, null does not have the length
property, try;
if((result.length)!=undefined){
userDG.dataProvider = result;
