Hi, thanks for your answer.
In fact, in the meantime, I've found a new way to do it.
Each time the timer launches the process, I add to the dataSet the value and
the date as a String.
--> In the addData function:
dataSet.addItem( { xValue : xValue , nb: nb } );
xDate = new Date();
xValue =
String(xDate.getHours()+":"+xDate.getMinutes()+":"+xDate.getSeconds());
-->The new mx:LineChart
<mx:LineChart width="100%" height="100%"
dataProvider="{dataSet}">
<mx:series>
<mx:LineSeries xField="xValue" yField="nb"
showDataEffect="{interp}" />
</mx:series>
<mx:horizontalAxis>
<mx:CategoryAxis categoryField="xValue" id="xAxe"/>
</mx:horizontalAxis>
<mx:horizontalAxisRenderers>
<mx:AxisRenderer labelRotation="45" axis="{xAxe}"/>
</mx:horizontalAxisRenderers>
</mx:LineChart>
Thanks for your help
So now, it works.
