How to change values format

Expected Behavior

allow to change values format

Actual Behavior

I’m trying to change a Pie chart values format to currency, but after I add the scales option it throws an error:

and this is the code:

import { Pie, mixins } from 'vue-chartjs'
// import { toCurrency } from 'utils/formatter.util'

const { reactiveProp } = mixins

export default {
  extends: Pie,
  mixins: [reactiveProp],
  props: ['options'],
  mounted () {
    // Overwriting base render method with actual data.
    this.renderChart(this.chartData, {
      responsive: false,
      maintainAspectRatio: false,
      legend: {
        display: false
      },
      scales: {
        yAxes: [{
          ticks: {
            callback: function (value, index, values) {
              console.log(value, index, values)
              return '' + value
            }
          }
        }]
      }
    })
  }

Oh sorry, did not saw that you are talking about the Pie chart. Well the Pie and Doughnut Charts do not have Y / X Scales. So there is no reason to pass in the scales object. So what you’re trying to do is change to tooltip right?

Then you have only to pass in the tooltip object.

@oswaldofreitas Well its not in the docs per se, but it’s kind of clear that the doughnut and pie charts, do not have X / Y axis. As their data is neigher linear nor logarithmic nor time based.

So there is no X or Y scale to style there.
