Chartjs - Tooltip With Rupee Symbol

I am using tooltip for my chart like this :- var opt = { .... animation: true, animationSteps: 100,

Solution 1:

Using Font Awesome Icons in a Tooltip

Just set the tooltipFontFamily

Note that you are not actually putting HTML in the canvas tooltip. You are just setting the font for the entire tooltip to FontAwesome. The side effect is that your numbers will also be in the FontAwesome font - which is usually ok. If this is not OK, custom tooltips would be the way to go (as @J-D and @Lalji Tadhani already noted)

You'll also have to wait a bit for the font files to load (I believe you'll have this problem even if you do custom tooltips)

Script

...
var myNewChart = newChart(ctx).Line(lineData, {
    tooltipFontFamily: "'FontAwesome'",
    tooltipTemplate: function (tooltip) {
        return"\uf156 " + numConversion(tooltip.value);
    }
});
...

CSS

Notice the place holder for the source

@font-face {
    font-family: 'FontAwesome';
    src: /* path to your font files */
    font-weight: normal;
    font-style: normal;
}
