Vue-chartjs: Not working at all

[icangku]

import {Line} from 'vue-chartjs'
export default {
  extends : Line,
  data(){
    return {
      tableData : [], 
      chartData: {
        labels: ['January', 'February'],
        datasets: [
          {
            label: 'Data One',
            backgroundColor: '#f87979',
            data: [40, 20]
          }
        ]
      }
    }
  },
  mounted () {
    this.renderChart(this.chartData)
  },

 <div class="col-lg-5">
                    <h4>Diagram Line Produk</h4>
                    <line-chart :chart-data="chartData"></line-chart>
                  </div>

Expected Behavior

Hey @icangku
I don't really understand what you are trying to do here.

You created your chart component, however you set your chartdata as a local data model.

However in the next snippet where you are using your line-chart component, you pass in the chart data as a prop?

1. Have you registered your component properly ?
2. Are you using Single File Components for your LineChart ? If so, have you removed the <template></template> tags ?
