Hi all,
I am hoping to build a suite of custom chart annotations and allow the
user to turn each one off and on as required. As a starting point I
had a look at Ely's wonderful chart sampler on quietlyscheming.com and
how he created his custom annotation (the one which shows crosshairs
when the mouse is over the chart and allows the user to select a range).
I thought to start with I'd split this functionality into two - i.e.
have separate annotation elements for the crosshairs and the range
selector - this way the user could use one or the other (or both).
The problem is that each annotation element works fine on its own but
if they are both added to the chart's <annotationElements> array then
only the one on top seems to receive mouse events, i.e:
<mx:annotationElements>
<test:RangeSelector/>
<test:Crosshairs/>
</mx:annotationElements>
...gives me only crosshairs, and:
<mx:annotationElements>
<test:Crosshairs/>
<test:RangeSelector/>
</mx:annotationElements>
...gives me the ability to select the range but no crosshairs appear.
Does anyone know how I can capture mouse events in *all* active
annotation elements?
Thanks,
Nick.
