I have installed Content Statistics with a module (EVOLUTION IN TIME) to Joomla! 3.9.27.
But, no data shows up. The following is the output source code.
How should I solve this?

google.load('visualization', '1', {packages:['corechart']});

			cs_options_204 = {



			height: 170,

			//colors: [],

			lineWidth: 2,

			

			

			

			chartArea: {left: 30,

								top: 10,

								width: '100%',

								height: 130},



			legend: 'none',

			fontSize: 11,

			hAxis: {showTextEvery: 1,

				textStyle: {color: '#666666'},

				title: null,

			},

			vAxis: {textStyle: {color: '#666666'},

				//format: '#,###.##'

			},

			pointSize: 0,

			backgroundColor: {fill:'transparent'},

			animation:{

					    duration: 500,

					    easing: 'out',

					    startup: true

					  }

			};
