[Chartjs]-JSON.parse label data from string var

✅

The newlabels is having wrong JSON string format. Let change ' with " with escape.

This will work:

var newlabels= "[\"label1\", \"label2\", \"label3\", \"label4\"]";
myChart.data.labels = JSON.parse(newlabels);

The variable newdatasets works with JSON.parse because its elements are number.

To be valid JSON, you need double-quotes. So the code below works.

Both examples work. You just need double quotes as part of the string itself.

var newlabels2= '["label1", "label2", "label3", "label4"]';
console.log(JSON.parse(newlabels2)); 

var newlabels3= "[\"label1\", \"label2\", \"label3\", \"label4\"]";
console.log(JSON.parse(newlabels3));

JSON does not support single quotes, so this code:

 var newlabels= "['label1', 'label2', 'label3', 'label4']";

Becomes this:

 var newlabels= '["label1", "label2", "label3", "label4"]';
