How to customize chartist beyond options?

[minusf]

Is there a way to inject in the current js something like labelInterpolationFnc for chartist?

https://gionkunz.github.io/chartist-js/api-documentation.html:

// In addition to the regular options we specify responsive option overrides
// that will override the default configutation based on the matching media queries.
var responsiveOptions = [
  ['screen and (min-width: 641px) and (max-width: 1024px)', {
    showPoint: false,
    axisX: {
      labelInterpolationFnc: function(value) {
        // Will return Mon, Tue, Wed etc. on medium screens
        return value.slice(0, 3);
      }
    }
  }],
  ['screen and (max-width: 640px)', {
    showLine: false,
    axisX: {
      labelInterpolationFnc: function(value) {
        // Will return M, T, W etc. on small screens
        return value[0];
      }
    }
  }]
];
