Re: [flexcoders] How to: Select range in Datagrid to set range in Chart?
Take a look here:
http://blog.kevinhoyt.org/2008/10/23/um-lots-of-flash-flex-and-zend-php-samples/in
the charts project.
Courtesy of Kevin Hoyt - he implemented a component that has a LineChart and
a DataGrid in a ViewStack (both linked to the same dataProvider), and a
HSlider to control zoom of the chart/grid. When you drag the HSlider to
define the range, both update to the selected range.

*private function processFilter*(item:Object):Boolean { return
item.Date_Collected = dfconv.format(linechart1.selectedChartItems.xValue.
*caretItem*).toString() item.Date_Collected =
dfconv.format(linechart1.selectedChartItems.*anchorItem*).toString();
If I could simply define the first and last item selected in a chart
multiple selection, it would do what I need. Any suggestions?

Okay, I'll do my best to explain what I'm trying to do and see if
anyone can point me in the direction of a good url and sample -
What I would like to do is select a range of data within a Datagrid,
so lets say 10 items out of the list 20.
Than whatever is selected in the Datagrid, appears in chart. It is
merely a graphical way of filtering a date range of data. Currently in
my example, I select the beginning and ending dates. So all I would
require to modify this is to be able to pass along the the first and
last entry selected and define which column will be used.
Any ideas? Cheers.
