Manoj Mohan,

Thank you for your reply. The example you provided confirms that document.getElementsByClassName("canvasjs-chart-toolbar")[0] is used as an array.

I noticed this works similarly through CSS as:

/*	change style of toolbar button	*/
.canvasjs-chart-toolbar button {
	width: 100px !important;
	border: 1px solid black !important;
}

/*	this css hides or displays multiple menu choices - 
	0 = print, jpeg, png, 1 = jpeg, png, 2 = print, png, 3 = print, jpeg, 4 = 0	*/
.canvasjs-chart-toolbar div>div:nth-child(3) {
	display: none !important;
}

The functions are also a good example but as I set a string using php for the filename with
exportFileName: “$stg” .
I do not know how the functions can be modified for that as they use filename numerous times.
