Drill Down Chart

Webix JS
1

Hi There. I’m trying to replicate chart drill down in webix.
I can probably go on the click event but will need to get the value of the item in the series that was clicked.
Lets say i have xAxis months and series sales. If i click on sales for the month the chart data:"" needs to change passing the month i clicked on as a var to the ajax call.
Any ideas.
Kind Regards

Hi,

onItemClick returns an item ID, so you can get the entire data item and particularly the month viachart.getItem(id).month. But it won’t detect which one of the series was clicked.

The only way is to get its index via theuserdata html arttribute:

onItemClick:function(id, e, node){
    console.log(id+" "+node.getAttribute("userdata"))
}

Thank you very much for all your help. Will try this method.

Hello,

I have tested this solution and with the version 4.4.5 I have always 0 with userdata.

I see the index in attribut: node.getAttribute(“webix_area_id”)

That is normal ?

Hello,

That is ok. I have made a mistake. Sorry.
The userdata is the serie index.
