Chartjs-Chart data will not load in ng2-charts/Chart.JS

  1. Open your DevTools and check if there are any errors in your console.
  2. Do a console.log(this.tempData) and console.log(this.timeData) and check if these variables have the same data format as your "static" data that worked.

Your problem is, that the Chart doesn’t notice that the data in the array has changed. You can reinitialize the data and then the chart gets an auto-refresh.

this.tempData = {...this.tempData}

If you still have the problem it would be nice if you provide the data of the console.log statements.
