Chartjs-ChartJS not updating

Seems to have been a couple of issues:

  1. The variable somechart doesn’t exist, you named it chart
  2. If you log out chart, you’ll see chart.config.data.datasets.data[2] = 5000;
    will not work because datasets is an array, so you can access it like this: chart.config.data.datasets[0].data[2] = 5000;

Heres a new fiddle with the fixes above added: https://jsfiddle.net/8whzsLgp/

Your chart variable is named chart but you’re trying to access it via somechart, which does not exist. Change the variable somechart to chart.

you are using the wrong variable for updating content replace your somechart to chart as you have initialize chart variable

var chart = new Chart

Updated your code as below 

chart.options.title.text = 'new title';
chart.config.data.datasets[0].data[2] = 5000;
chart.update();

you need to specify the index of the dataset in order to update the data.
