How do I use getLastItem on creation of chart?

[npfdev]

Hi,

I need to draw some horizontal lines across my Line graph. I was trying to do it by adding a LineSeries with 2 points on creation of the graph. However, I cant seem to dynamically get the last point in the graph right after the chart is created. Whenever I do:
myChart.getLastItem(ChartBase.HORIZONTAL)

it returns the first item in the series? I was trying to attach my function to the creationComplete event - I am guessing there is another one I should use - however I can't seem to find it.

If I add my code to a button, then it draws the line just fine when I press it.

Any help would be appreciated. Thanks,

Nathan

I would have imagined myChart.getLastItem() would return the last point on the horizontal chart series... Curiously, what happens if you use myChart.getFirstItem( ChartBase.HORIZONTAL ) ?

I guess you could also try myLineChart.series[0].items[ items.length-1 ]
