I tried these approaches. Im simply trying to tie lineseries “two” to the axis with label {v4}?

This is what I have:

is it possible that I can add multiple line series to this chart with these lines tied to a single axis renderer placed on the right side, ranging from 0-600 lets say.

Thanks,

Geoff

Outstanding job! This code popped right in and works great. Thank you so much for this valuable information. I doubt, but I hope I can help you out in some small way in the future.

Thanks much

You rock! Using the if else in the hitData is what I was trying however I am rather new to all this and could not work out the hitData.element bit. Its late so tomorrow I will implement your direction and see what happens.

Thanks much for your help.

What I mean by sibling is that the LineSeries will have to be alongside the ColumnSet rather than within it. However, I believe this is not your problem. The custom data tip function is set at the chart level rather than the series level, so it applies to all series in the chart. Therefore, the line of code where you cast to a ColumnSeries will throw an error when the data tip function is invoked as a result of mousing over the LineSeries. You need to change the data tip function to check the type of the element, i.e. something along the lines of:

private function myDataTipFunction(hitData:HitData):String
{
    if (hitData.element is ColumnSeries)
        return myColumnSeriesDataTipFunction(hitData);
    else if (hitData.element is LineSeries)
        return myLineSeriesDataTipFunction(hitData);
    else
        return "Unrecognised series type";
}
 
private function myColumnSeriesDataTipFunction(hitData:HitData):String
{
    var series:ColumnSeries = ColumnSeries(hitData.element);
    var item:ColumnSeriesItem = ColumnSeriesItem(hitData.chartItem);
    var quarter:Object = xAxis.formatForScreen(item.xValue);
    var value:Number = Number(item.yValue) – Number(item.minValue);
    var myComment:String = hitData.item.comment;//comments
    return series.displayName + "\n" +
        "——————\n" +
        quarter + "\n" +
        "——————\n" +
        "Value:" + value + "\n" +
        "——————\n" + 
        "Comments:\t\t\n" + myComment; 
}
 
private function myLineSeriesDataTipFunction(hitData:HitData):String
{
    var series:LineSeries = LineSeries(hitData.element);
    ....
    return ...;
}

Thanks so much for your work. I shopped the net looking for the solution to this problem. Yours is far and away the most elegant. I have a problem im sure is a simple solution however I cant see it. Im trying to incorporate a line series with a columnSet. Columns work fine but the lineseries throws an error which im sure lies with your statement above.
“You can stack as many series as you want; just add more series as children of the ColumnSet. To add a line to the chart, simply add a LineSeries as a sibling of the ColumnSet”.

I dont understand “sibling”.
Can you explain how I add a lineseries?

Your help is greatly appreciated!

thanks in advance

Heres my partial code block.

private function myDataTipFunction(hitData:HitData):String
{

var series:ColumnSeries = ColumnSeries(hitData.element);
var item:ColumnSeriesItem = ColumnSeriesItem(hitData.chartItem);
var quarter:Object = xAxis.formatForScreen(item.xValue);
var value:Number = Number(item.yValue) – Number(item.minValue);
var myComment:String = hitData.item.comment;//comments
return “” + series.displayName + “\n” +
“——————\n” +
“” + quarter + “\n” +
“——————\n” +
“Value:“+value+”\n” +
“——————\n”+
“Comments:\t\t\n” + myComment;

}

Theres actually quite a lot of .Net/Flex/Air dev going on (integration tools like WebOrb and FluorineFx and are quite big). Mostly I think its because people were’nt too confident about Silverlight when it came out first, although its probably improved a lot by now.

Thanks for that code – looks like a really good solution if you want to avoid custom classes. The only very minor issue I can see is that you are building up the totals value every time the function is called. This could cause a small performance hit in extreme cases but in general it will be absolutely fine.

It’s nice to see you’re using the C#/Flex combination. I’d have thought most C# developers were shifting towards Silverlight these days (like my collegues Colin and Gergely).
