I'm having an issue with getting multiple series to plot correctly on
a chart with the same CategoryAxis.
I have several ArrayCollections...for weight, height and BMI. Each
ArrayCollection has a date and value. I need to use actionscript to
create each one as a series and add that to the chart. I created an
ArrayCollection that just has all the dates for the points to plot. I
thought I could use this for the CategoryAxis dataProvider but when I
do it this way it seems that it plots the points at the wrong
dates.
Here is a sample of how I am adding one of the series and the
CategoryAxis:
var hAxis:CategoryAxis = new CategoryAxis();
hAxis.categoryField = 'startDate';
hAxis.dataProvider = allTrendingDates;
hAxis.labelFunction = lineChartDateFormat;
linechart.horizontalAxis = hAxis;
var bmiSeries:LineSeries = new LineSeries();
bmiSeries.dataProvider = bmiTrendEntries;
bmiSeries.displayName = 'BMI';
bmiSeries.yField = 'bmi';
linechart.series.push(bmiSeries);
Here is my chart:
<mx:PlotChart id="linechart" height="252" width="783" paddingLeft="5"
paddingRight="5" showDataTips="true" y="130">
<mx:verticalAxis>
<mx:LinearAxis baseAtZero="{baseZeroCheckBox.selected}"/>
</mx:verticalAxis>
<mx:horizontalAxis>
<mx:CategoryAxis categoryField="startDate"
labelFunction="lineChartDateFormat"/>
</mx:horizontalAxis>
</mx:PlotChart>
Any help is greatly appreciated.
