[harikm007]

Adjusting the date granularity in charts is crucial for effective data analysis. Users often want to switch between yearly, quarterly, or monthly views to identify trends, analyze seasonal performance, or evaluate specific campaigns.

This straightforward widget script lets users toggle between year, quarter, and month views effortlessly, enhancing interactivity and simplifying data exploration.

widget.on('processresult', function ( se, ev ) {
    	ev.result.chart.spacing = [20, 20, 77, 20 ]
    });
	
	widget.on("domready", function(se){
	    
    	const chart = widget.chart[0][Object.keys(widget.chart[0])[0]].hc;
    	const chartContainer = prism.activeWidget ? $('.highcharts-container') : $(`widget[widgetid=${widget.oid}] .highcharts-container`);
    
    	//Time period dropdown
    	const timePeriods = {
    	                        'Weekly': 'weeks',
    					        'Monthly': 'months',
    					        'Quarterly': 'quarters',
    					        'Yearly': 'years'
    	                    };
    	
    	let ddTimePeriodId = `select-timeperiod-${widget.oid}`;
    	let dropdownHTMLTimePeriods = `<select name="select" id="${ddTimePeriodId}"></select>`;
    	
    	if($(`#${ddTimePeriodId}`).length)
    	{
    		$(`#${ddTimePeriodId}`).remove();
    	}
    	
    	chartContainer.before(dropdownHTMLTimePeriods);
    	
    	for(let key in timePeriods){
    		
    		$(`#${ddTimePeriodId}`).append(`<option value="${key}">${key}</option>`);
    		
    	}
    	
    	document.getElementById(`${ddTimePeriodId}`).value = Object.keys(timePeriods).find(key => timePeriods[key] == widget.metadata.panels[0].items[0].jaql.level);
    	var select = document.getElementById(`${ddTimePeriodId}`);
    
    	select.addEventListener('change', (e) => {
    		
    	  let selectedItem= e.target.value;
    
    	  widget.metadata.panels[0].items[0].jaql.level = timePeriods[selectedItem];
    
    	  widget.refresh();
    
    	});
	});

is there a way to make this work for pivot tables? i.e the columns are months, but we might want to collapse it to be Quarters
