Event Listener for bar chart

Hi Team,

We are evaluating different javascript chart options for one of the charting requirement in our product. But going through the JS chart for Bar Chart, I did not find any clear documentation for click events.

Could you please post a link to document or a sample example where we can click on bar items to drill down further into data.

Thanks,
Nilesh

Hello,

The Dashboard control and the various inheriting chart classes expose the DataItemClicked event, which is raised, when a chart data element is clicked by the user. To subscribe to the event, pass a handler function like this:

Code (Javascript)
Select All
barChart.dataItemClicked.addEventListener(function (args) {
    // do something in response to the event.
}); 



We will provide you with an example showing a possible way to drill down into data shortly.

Regards,
Lyubo

Hi,

The following sample shows one way to implement drilling down to a more detailed view of the data and then back to the summary:
