Just tried to add a mouse click event on my chart ... and it fails (nothing happens)

$('#chart1').bind('dataPointMouseUp', function(e, data) {
alert(1);
});

It's a line chart ... and it works with a column chart.

Does it mean that I can't detect a simple mouse click on a data point of a line chart ?

Hi,

I'm checking this one and it seems to work. Do you have markers on your line chart?

No I didn't. And you're right, adding markers make the event work.
In fact, it's obvious in a certain way.
But this particular chart have lots of points, so adding markers is visually bad.
I will make tests with different sizes and colors ...

Thanks for your help.

'dataPointMouseUp' event in the line chart requires markers. If you don't want to have markers you can try storing the highlighted data point with:

http://www.jqchart.com/jquery/chart/ClientSideEvents/DataHighlightingEvent

and handle the mouse up event of the whole chart.
