Absolutely. I have a combination line/area chart that has this
feature. The basic idea is to have a chart that is showing only a
portion of the available dataset, and Christophe Coenraets has a great
example of how to do this in his charting components explorer:
http://flexapps.macromedia.com/flex15/chartexplorer/explorer.mxml.
Look for "Slider selection of time axis" under Misc Techniques and
Examples at the bottom of the tree. From there, just add an
HScrollBar component that controls the start and end positions of the
HSlider. Here are some excerpts from my code:
In ActionScript:
function rangeScroll(o: Object) : Void {
slider.values = new Array(o.scrollPosition, o.scrollPosition +
o.pageSize - 1);
sliceResults();
}
and in MXML:
<mx:HScrollBar id="timescroll" minPos="0" maxPos="{scrollbarMaxPos}"
width="100%" scroll="rangeScroll(event.target);" />
You'll probably also want to set the various page size and scroll size
properties of the scrollbar according to your own needs.
