Just wondering if there's a way to get a handle to the Highcharts javascript object that might have been created when generating the splunk chart? I was hoping to be able to dynamically show and hide additional overlays on a specific chart via javascript.
Was able to find the handle. For any that might be looking, the container seems to be the div[data-highcharts-chart] tag.
From custom javascript included in the SimpleXML:
var thehcobject = $('#mychartid div[data-highcharts-chart]').first().highcharts();
