無論如何在圖表js中將一個條形圖與另一個條形圖重疊而不堆疊它們？-有解無憂

我嘗試使用stackandoffset但它似乎不起作用

這是我的代碼：

import React, {
  useEffect
} from 'react';
import {
  Bar
} from 'react-chartjs-2';
import useWindowWidth from 'wa-shared/src/hooks/useWindowWidth';

const state = {
  count: 0,
  data: {
    labels: [
      ['Total Users'],
      ['Users with', 'Active', 'Session'],
      ['Created 1', 'or More', 'Videos'],
      ['Shared 1', 'or More', 'Videos']
    ],
    datasets: [{
        backgroundColor: '#26863D',
        data: [70, 66, 57, 1],
        barThickness: '35',
      },
      {
        backgroundColor: '#F2F2F2',
        data: [70, 70, 70, 70],
        borderRadius: '5',
        barThickness: '35',
      }
    ]
  }
}

const App = ({}) => {
  const width = useWindowWidth();
  useEffect(() => {});
  return ( <
    div className = 'singlebar-chart'
    id = "barchart" >
    <Bar> data = {
      state.data
    }
    options = {
      {
        scales: {
          x: {
            grid: {
              display: false,
            },
            offset: true,
            ticks: {
              maxRotation: 0,
              minRotation: 0,
              font: {
                size: 8,
              }
            },
          },
          y: {
            min: 0,
            max: 100,
            ticks: {
              fontColor: '#8A8A8A',
              font: {
                size: 8,
              },
              stepSize: 25,
              callback: function(value) {
                return value   "%"
              },
            },
            scaleLabel: {
              display: true,
              labelString: "Percentage",
            },
            grid: {
              display: false,
            }
          }
        },
        plugins: {
          legend: {
            display: false,
          },
        }
      }
      </Bar>
    </div>
  )
}

export default App;

.singlebar-chart{
    width: 95%;
}

uj5u.com熱心網友回復：

您可以使用第二個 x 軸并將其他資料集映射到該軸：

var options = {
  type: 'bar',
  data: {
    labels: ["Red", "Blue", "Yellow", "Green", "Purple", "Orange"],
    datasets: [{
        label: '# of Votes',
        data: [12, 19, 3, 5, 2, 3],
        backgroundColor: 'pink'
      },
      {
        label: '# of Points',
        data: [7, 11, 5, 8, 3, 7],
        backgroundColor: 'orange',
        xAxisID: 'x2'
      }
    ]
  },
  options: {
    scales: {
      x: {},
      x2: {
        display: false // Dont show the axes since it is just a duplicate
      }
    }
  }
}

var ctx = document.getElementById('chartJSContainer').getContext('2d');
new Chart(ctx, options);

<body>
  <canvas id="chartJSContainer" width="600" height="400"></canvas>
  <script src="https://cdnjs.cloudflare.com/ajax/libs/Chart.js/3.8.0/chart.js"></script>
</body>

盡管這給出了與在 x 軸上設定堆疊為真的結果相同的結果。
