[Chartjs]-Vue-chart.js : Data available as computed properties, but not showing in chart

Try making a computed property to calculate the chart data:

Look at chart.js at https://www.webpackbin.com/bins/-KpNBtUKQ67-jSFRHtNe

datasets: [
        {
          label: 'Ticketstatus',
          backgroundColor: '#f87979',
          data: this.orderStatusChartData
        }

.

computed: {
    orderStatusChartData () {
      let chartData = []
      this.statOrderstatus.forEach(function(orderStatus) {
          chartData.push(orderStatus.doc_count)
      })      
      return chartData
    }
