Vue-ChartJS无反应

Question

构建图表和具有不动态的图表非常新，即使存在数据并加载到数据集。

我的chart.js文件如下所示。

import { Line, mixins } from 'vue-chartjs'
const { reactiveProp } = mixins

export default {
  extends: Line,
  mixins: [reactiveProp],
  props: ['options'],
  mounted () {
    // this.chartData is created in the mixin.
    // If you want to pass options please create a local options object
    this.renderChart(this.datacollection, this.options)
  }
}

我的成分是：

template>
    <div class="panel panel-default mbm">
        <table class="table table-condensed table-bordered mbn">
            <thead>
                <tr>
                    <td class="active pll prl ptm pbm">
                        <b>
                            <a @click="showLiveChat()">Chat</a>
                            <span class="pull-right">Live Chart</span>
                        </b>
                    </td>
                </tr>
            </thead>
        </table>
        <div class="panel-body">
        <Profit :chart-data="datacollection" :options="chartOptions"></Profit>
        </div>
    </div>
</template>
<script>
import Profit from "@/components/Charts/profitLive.js";
export default {
  components: {
    Profit
  },
  props: {
    userSelf: {
      type: Object,
      required: true
    }
  },

  data() {
    return {
      datacollection: [],
      balance: [],
      bet: [],
      chartOptions: {
        chart: {
          title: "Live Bet data"
        },
        colors: ["#e0440e"],
        height: 270,
        width: 500,
        hAxis: {
          title: "Bets"
        },
        vAxis: {
          title: "Profit"
        }
      },
      profit: [],

    };
  },
  methods: {
      fillData () {
        this.datacollection = {
          labels: [0, 1000],
          datasets: [
            {
              label: 'Profit',
              backgroundColor: '#f87979',
              data: this.balance
            },
          ]
        }
      },

    },
   mounted () {
      this.fillData()
    },
   watch: {
    userSelf() {
      this.balance.push(parseInt(this.userSelf.balance));
      this.Profit.updateData();
    }

  }
};
</script>

因此，我确保推送更新了数据，并且图表使用了上述数据，更多的是关于反应性图表，以及在加载新数据时实际加载到屏幕上的用户的数据。

您正在传递chartData，但在组件中使用datacollection。

请尝试更新：

import { Line, mixins } from 'vue-chartjs'
const { reactiveProp } = mixins

export default {
  extends: Line,
  mixins: [reactiveProp],
  props: ['options', 'chartData'],
  mounted () {
    // this.chartData is created in the mixin.
    // If you want to pass options please create a local options object
    this.renderChart(this.chartData, this.options)
  }
}
