Re: [flexcoders] Filters for multiple LineSeries in a LineChart - Calling ChartMan Ely!
Alright, I'm getting close but having issues.well it actually taking my changes, ironically enough. My guess is because I'm not altering the _renderData in the actual graph since it's extendedbut here, maybe you can explain where I went wrong. No matter how I change _renderData, it never effects the actual graph.
package com.rsi.briefingbook.view.chart { import mx.charts.series.LineSeries; import mx.charts.series.renderData.LineSeriesRenderData; import mx.charts.series.items.LineSeriesItem;
import mx.charts.chartClasses.CartesianTransform; import mx.collections.CursorBookmark; public class FilteredLineSeries extends LineSeries { private var _renderData:LineSeriesRenderData;
private var _xField:String = ""; private var _yField:String = ""; override protected function updateFilter():void { _renderData.filteredCache = _renderData.cache;
for(var i:int = 0; i < _renderData.filteredCache.length; i++) { var temp:LineSeriesItem = _renderData.filteredCache[i]; trace(temp); }
super.updateFilter(); } override protected function updateData():void { var renderDataType:Class = this.renderDataType; _renderData= new renderDataType();
_renderData.cache = []; if (dataProvider) { cursor.seek(CursorBookmark.FIRST); var i:int = 0; var itemClass:Class = itemType;
while (!cursor.afterLast) { _renderData.cache[i] = new itemClass(this,cursor.current,i); i++; cursor.moveNext();
} cacheDefaultValues(_yField,_renderData.cache,"yValue"); cacheIndexValues(_xField,_renderData.cache,"xValue"); }
_renderData.validPoints = _renderData.cache.length; super.updateData(); } }}On 10/19/06, Jonathan Miranda

Hi Jon. Unfortunately, there's nothing in charts that will
do what you want. What you're looking for is basically a pivot (well...if
you're looking for just one brand it's a filter, but if you're looking for one
series per brand it's more of a pivot), and charts don't support that out of the
box.
You have three options:
1) prefilter the data yourself, the manual
way
2) subclass lineSeries, add a 'filterField' and
'filterValue' property, and override the updateFilter function to filter on
those values.
3) write a pivot class that accepts parameters on what to
filter on, what to create multiple series on, what to aggregate on, and have it
spit out a set of series with custom dataproviders assigned.
I've got a skunkworks version of #3 I've been tooling
around with for a little while, but it's not ready for the outside world
yet. In the meantime, try #1 or #2.

Heh, maybe he'll see this before MAX :)Anyways, here's my question -
I've done this before, but I can'tremember how nor find the code. I've got a
data set like
thefollowing:Month.Dollar.Category.Brand..Jan.500..IT.Blue..Feb.700..JO.Red..Mar.600..AC.Blue..Jan.100..IT.Green
..Feb.200..JO.Red..Mar.300..AC.Blueok
so, Month will be my x-axis. Dollar will be my y-axis, tallied up.I want the
entire LineChart to filter on Category (assuming I'll justneed to sort this
based on altering the dataProvider itself)...but myproblem is I need a
LineSeries for each Brand.So my first guess
was..Which
does give me the lines I need, but I need some way to have aLineSeries only
show data where brand=uniqueBrandList.selectedItem.What's the filter
mechanism for a LineSeries besides the yField? Isthere some trick in that
field or is there a property/function I'mmissing on how I can only show data
where Brand=X? I thought "hey, usefilters" but that's the Effects, not for
data :)Any help would be nice-Jon Miranda
