You can filter chart data with chartEvents :

Vue.component("gchart", VueGoogleCharts.GChart);
new Vue({
  el: '#demo',
  data() {
    return {
      chartData: [
        ['Month', 'New', 'Verified', 'Regitered ID', 'On Playing', 'Finished', 'Active', 'Inactive'],
        ['January', 7, 4, 18, 15, 9, 10, 0],
        ['February', 16, 22, 23, 30, 16, 9, 8],
        ['March', 10, 2, 20, 13, 14, 21, 18]
      ],
      chartOptions: {
        chart: {
          title: "Player Performance"
        },
        legend: { position: 'top', maxLines: 3 },
        bar: { groupWidth: '75%' },
        isStacked: true,
      },
      chartEvents: {
        'click': (e) => {
          const numberPattern = /\d /g;
          const idx = Number(e.targetID.match(numberPattern)[0])
          this.isFiltered ? this.allData() : this.filterChart(idx)
        }
      },
      newData: [],
      isFiltered: false
    };
  },
  methods: {
    filterChart(idx) {
      this.allData()
      for(let i = 0; i < this.newData.length; i  ) {
        this.newData[i] = [this.newData[i][0], this.newData[i][idx   1]]
      }
      this.isFiltered = true
    },
    allData() {
      this.newData = [...this.chartData]
      this.isFiltered = false
    },
  },
  mounted(){
    this.allData()
  }
})
