I went over the Chart.js documentation and did not find anything on number formatting ie) 1,000.02 from number format "#,###.00"
I also did some basic tests and it seems charts do not accept non-numeric text for its values
Has anyone found a way to get values formatted to have thousands separator and a fixed number of decimal places? I would like to have the axis values and values in the chart formatted.
There is no built-in functionality for number formatting in Javascript. I found the easiest solution to be the addCommas function on this page.
Then you just have to modify your tooltipTemplate parameter line from your Chart.defaults.global to something like this:
tooltipTemplate: "<%= addCommas(value) %>"
Charts.js will take care of the rest.
Here's the addCommas function:
function addCommas(nStr)
{
nStr += '';
x = nStr.split('.');
x1 = x[0];
x2 = x.length > 1 ? '.' + x[1] : '';
var rgx = /(\d+)(\d{3})/;
while (rgx.test(x1)) {
x1 = x1.replace(rgx, '$1' + ',' + '$2');
}
return x1 + x2;
}
