Widget Display Not Updating On Dashboard Filter Change

Hi all,

So I am running the following script on my widget (using 'edit script') in order to grab the date of the maximum dollars for a year using a different bar chart widget on the dashboard, and display that date (along with the $ amount) on an indicator widget

var dateStr = '';

widget.on('processresult', function(e,v) {
	var results = widget.queryResult;
	console.log(results);
	

	
	var maxNum = results.value.data;
	var replaceNum = results.secondary.data;
	//var dateStr = '';
	console.log(results);
	var widg = dashboard.widgets.get('6633bbf55a7e230040304e8c');
	var widgResult = widg.rawQueryResult.values;
	console.log(widgResult);
	$.each(widgResult, function(index, item) {
		let date = item[0].data;
		let amt = item[1].data;
		if (amt === maxNum) {
			dateStr = date;
		};
	});
	//results.secondary.data = dateStr.substring(0, 10);
	//results.secondary.text = dateStr.substring(0,10);
});


widget.on('render', function(se, ev) {
	
	var results = widget.queryResult;
	results.secondary.data = dateStr.substring(0, 10);
	results.secondary.text = dateStr.substring(0,10);

});

widget.refresh();
		  

	

 This works, and gets me the proper date. However, when I open the dashboard (/refresh the page), or change filters, the displayed date doesn't update, and only updates when I do something like changing the widget's width on the dashboard manually, as though I am manually refreshing the widget's render state or something. 

Can anyone help me with a solution so that the widget properly displays the info without having to manually change its size to refresh the display?

Thanks in advance
