Disable on-click listener in chart via script [message #1033508] Thu, 04 April 2013 05:49 Go to next message

Hi,

I know that I can disable the whole interactivity of a chart e.g. in beforeGeneration() via

chart.getInteractivity().setEnable(false);


But how can I disable just the on-click listener of the y-series interactivity and legend interactivity while keeping the on-mouse-over listener enabled?

The use case is that I have to programmatically disable the possibility to invoke a drill-down while it should still be possible to get a tooltip with the series' data.

Thanks in advance for any input! Cheers, Jakob

Something like:

series.getTriggers().remove(index) should do the trick, where "index" is the onClick event's index, either 0 or 1 since you just have two events being used.

Let me know if this does it for you. If not, I'll take a closer look.

Hi,
thanks for the reply. Unfortunately I can't get it working. I assume this code is supposed to be placed in the chart's beforeDrawSeries() method, right?

function beforeDrawSeries( series, isr, icsc )
{
	var isFurtherDrillDown = myChart.isFurtherDrillDown();
	if (isFurtherDrillDown == false){
		series.getTriggers().remove(0);
	}
}

(myChart is a java object of my own. It is valid and is not the reason for the exception)

I get the following exception:

Apart from that, I think that this code is supposed to disable the onClick listener for the y-series interactivity. Furthermore, I have to disable the legend onClick listener as well. How would I do that?

Oh ok, I solved it and it all works fine now!

Obviously, the beforeDrawSeries() method was called twice. On the first call, series.getTriggers().size() is 0, on the second call it is 2. This is the case even though I only have one series. Anyways, using the following workaroud it works. And by the way, as you may have known but as I did not but as I know now, getTriggers().remove() removes the onClick listeners both for the y series and for the legend.

function beforeDrawSeries( series, isr, icsc )
{
	if (series.getTriggers().size() > 0){
		var isFurtherDrillDown = myChart.isFurtherDrillDown();
		//	chart.getInteractivity().setEnable(isFurtherDrillDown);
		if (isFurtherDrillDown == false){
			series.getTriggers().remove(1);
		}
	}
}


Thanks again for your help! Cheers, Jakob
