There is a spelling mistake replace yAxesID
with yAxisID
, and the dataset population should look like the below code or you can see the fiddle for your reference -> https://jsfiddle.net/69p7Lsth/1/
datasets: [{
label: 'Gravity',
yAxisID: 'SG',
data: [1.07, 1.045, 1.030, 1.014, 1.012],
backgroundColor: '#ff6384' //red
}, {
label: 'Temp F',
yAxisID: 'Temp',
data: [8, 66, 78, 66, 76],
backgroundColor: '#36a2eb' //blue
}]
