[flexcoders] DateTimeAxis labels
My stakeholders almost always seem to want something for DateTimeAxis labels that I can't give them out of the box. Example: I have a weeks worth of data in 15-minute increments, and would like the labels at 12AM and 12PM. Or if only one per day, at 12PM rather than 12AM. But if I set labelUnits to hours, I get one label per day at 12AM. Anyone discovered any tricks?
Re: [flexcoders] DateTimeAxis labels
Have you looked at using a custom IAxisRenderer for the series in which you limit the labels which are shown? You would be able see the labels which are to be displayed and show/hide them accordingly. I believe that you'll find the setter for gutters has the labels which are added automatically.

Re: [flexcoders] DateTimeAxis labels
Before embarking on potentially time-consuming or risky customization, we usually have to weigh other priorities. But thanks, I'll keep that in mind, and look into it when time permits.

[flexcoders] dateTimeAxis labels missing from entire project?
Is it possible to have some type of global setting that removes label
from the charting axes?
I've got a basic LineChart with a DateTimeAxis that is missing labels.
But when I copy the class to a new project and display the chart by
itself, the labels are there and display fine.
I would like the labels to show, and I am not manipulating this class
at all from anywhere else so I can't figure out how the labels might
be getting shut off.
This is my class:
mx:Canvas xmlns:mx=http://www.adobe.com/2006/mxml;
creationComplete=onInit() width=100% height=100%
mx:Script
![CDATA[
import mx.collections.ArrayCollection;
[Bindable] public var dataProvider:ArrayCollection;
//this is just to populate the data with a diagonal line
public function onInit():void {
dataProvider = new ArrayCollection();
var i:int = 10;
var date:Date;
while(i 0) {
date = new Date(2008, 8, 30-i, 10,11, 12);
dataProvider.addItem({date:date, yField:i});
i--;
}
}
]]
/mx:Script
mx:LineChart id=lineChart width=100% showDataTips=true
dataProvider={dataProvider} height=100%
mx:horizontalAxis
mx:DateTimeAxis id=dateTimeAxis labelUnits=days
dataUnits=days /
/mx:horizontalAxis
mx:verticalAxis
mx:LinearAxis id=yAxis/
/mx:verticalAxis
mx:series
mx:LineSeries horizontalAxis={dateTimeAxis}
yField=yField xField=date /
/mx:series
/mx:LineChart
/mx:Canvas
