chart js line chart dont show below 0

had an issue where the chart was displaying values in the negative, and wanted to start the chart at 0 and no go below. the additional option fixed this issue. 

Javascript

	options: {
		scales: {
			yAxes: [{
				ticks: {
					beginAtZero: true
				}
			}]
		}
	}

HTML

<canvas id="myChart" style="width:100%;max-width:700px"></canvas>

Scripts

<script  
src="https://cdnjs.cloudflare.com/ajax/libs/Chart.js/2.9.4/Chart.js">  
</script>

Javascript

const xValues = ["1","2","3"]; 
const yValues = ["5.51","10.21","1.23"]; 

  
new Chart("myChart", {  
	type: "line",  
	data: {  
	labels: xValues,  
	datasets: [{  
		label: "Share Price",
		backgroundColor:"rgba(255, 210, 0,1.0)",  
		borderColor: "rgba(0,0,255,0.1)",  
		data: yValues
	}]  
	},  
	options: {
		scales: {
			yAxes: [{
				ticks: {
					beginAtZero: true
				}
			}]
		}
	}
