overlapping series line chart - flex 1.5
Robert --
the good news, this problem is dealt with
in Flex 2 --- charts can display multiple datatips if the mouse is over
multiple datapoints. The bad news is you're using Flex 1.5.
You could try and mimic this behavior by
rewriting the datatip behaviors yourself. You have the mouseData events,
which tell you when the mouse moves over and out of datapoints, and there's a
method on the individual series called
findDataPoint(x:Number,y:Number,sensitivity:Number); which you can call to find
any datapoints at a given x/y coordinate. So you could, on mouseOverData
events, iterate over the series, find out if there are multiple datapoints at
that point, and show your own tooltip (using the popup manager) as appropriate.
(Another idea...set a custom
dataTipFunction, and do the check for multiple data points _there_, and format
your datatip string appropriately).
Ely.

Subject: [flexcoders] overlapping
series line chart - flex 1.5
Does anyone have an elegant solution on
how to handle a line chart when, for example, we have 3 series in our line
chartEquities, Assets, and a Total. 3 separate lines. In a
specific case, Assets is 0 for all date points, so Equities and Total are
exactly the same, hence their lines overlap each other identically.
To a user,
this might not be immediately intuitive if they only see the chart and not the
underlying data. Is there a way to handle this? I mean would this
just be a situation where wed have to pre-analyze the data of the chart,
check if a specific series is identical to the total and if its true, in
the mouse-over datatip renderer wed have to display something that
indicates to the user that this series and the total are identical? Or is
there some nifty built-in functionality to already handle such instances where
series are identical?
