[Chartjs]-Trying to update background color on chart.js

Since, there is no native way of changing the background color of chart in ChartJS, hence, you would have to do some css styling to accomplish so …

#myChart {
  background-color: #22293d;
}

additionally, if you want the graph­‘s fill color to match chart­‘s background color then, you need to set datasetFill property to false in your chart options …

var optionsNoAnimation = {
   datasetFill: false,
   ...
}

Here is the working demo on JSFiddle
