百分比栏的javascript图形库[关闭]

Question

我正在使用 Google 图表以图形格式表示我的数据。但我需要以如下格式显示其中一个图形。从技术上讲，它类似于饼图，但呈直线。

你们知道我可以用来获取这种格式的任何 javascript 库吗？

谢谢

Answer 1

您的典型条形图与您想要的不相似，但使用数据和图表选项可以达到非常相似的效果：

  google.setOnLoadCallback(drawChart);
  function drawChart() {

      //your data in kbytes
      var data = {Free: 226480000, Audio: 6300, Movies: 48100, Photos: 1300000, Apps: 9120000, Backups: 0, Other: 13190000 }


      var sorted_data=[]; // seems you want it sorted by lowest to highest
      var total=0; // total space

      for(var key in data){
          total+=data[key];
          if(key != 'Free'){
              sorted_data.push([key + ' '+  bytesToSize(data[key]), {v:data[key], f:bytesToSize(data[key]) }]) // add the label we will use and the size for the bar
          }
      }

      sorted_data.sort(function(a,b){return a[1]-b[1]}) // sort by size, lowest to highest

      sorted_data.push(['Free' + bytesToSize(data.Free), data.Free]) // add free space to the end of the array

      var chart_data=[['Machine'], ['']];



      for(var i=0;i<sorted_data.length;i++){
          chart_data[0].push(sorted_data[i][0]); // add the label
          chart_data[1].push(sorted_data[i][1]); // add the value
      }


      var title = 'Macintosh HD        ' + bytesToSize(data.Free) + ' free out of ' + bytesToSize(total); // create title (if you want to have one part on the right and the other on left, add it with html and put title='')


    chart_data = google.visualization.arrayToDataTable(chart_data);



      var options = {
      title: title,
        isStacked: true,
        legend:{position:'bottom'}, // put legends on bottom
        hAxis: {gridlines:{color:'transparent'}, ticks:[]}, // remove gridlines and ticks
        height: 200, // little height, we don't need much
        series:{}

    };
      var cols=chart_data.getNumberOfColumns()-2;
      options.series[cols]={color:'transparent', visibleInLegend: false} // put free space as transparent

    var chart = new google.visualization.BarChart(document.getElementById('chart_div'));

    chart.draw(chart_data, options);
  }

function bytesToSize(kbytes) { //function that translates kbytes to the fortmat you wanted
   var bytes=kbytes*1000;
   if(bytes == 0) return '0 Byte';
   var k = 1000;
   var sizes = ['Bytes', 'KB', 'MB', 'GB', 'TB', 'PB', 'EB', 'ZB', 'YB'];
   var i = Math.floor(Math.log(bytes) / Math.log(k));
   return (bytes / Math.pow(k, i)).toPrecision(3) + ' ' + sizes[i];
}

设法解决了http://jsfiddle.net/vivekbhusal/3n78tc8p/ @juvian 给出的解决方案也很好

          google.setOnLoadCallback(drawChart);
      function drawChart() {
        var data = google.visualization.arrayToDataTable([

          [120,  2, 0, 5],
        ]);

        var options = {
            isStacked: true,

      vAxis: {
