How to group a stacked bar chart?

[Usman Mani]

Hi,

I am trying to group a stacked bar chart on two different target index for a corechart package. It can be done with bar package but then I cant apply annotations to bar package.

Here is my code:

     

 google.setOnLoadCallback(drawVisualization);


      function drawVisualization() {
        // Some raw data (not necessarily accurate)
        /* var data = google.visualization.arrayToDataTable([
         ['Month', 'Bolivia',{type: 'number', role: 'annotation'}, 'Ecuador', 'Madagascar', 'Papua New Guinea', 'Rwanda', '', {type: 'number', role: 'annotation'}],
         ['Application', -5,0, 2, 2, 8, 0, 17, 17],
         ['Friend', 4,0, 3, 5, 6, 2, 20, 20],
         ['Newspaper', 6,0, 1, 0, 2, 0, 9, 9],
         ['Radio', 8,0, 0, 8, 1, 1, 18, 18],
         ['No Referral', 2,0, 2, 3, 0, 6, 13, 13]
      ]); */
 
  var data = new google.visualization.arrayToDataTable([
 ["Users", "Normal", {type: 'number', role: 'annotation' },  "SLA", {type: 'number', role: 'annotation' },  "HP", {type: 'number', role: 'annotation' }, "HP-SLA", {type: 'number', role: 'annotation' }],
 ["John D.", 3,3, -2,2, 1,1,  0, 0],
 ["Muhammad E.", 4,4, -2,2, 5,5, -3,3],
 ["Steve B.", 5,5, -3,3, 1,1, -1,1],
 ["Donna P.", 5,5, -1,1, 6,6, -3,3],
 ["Altamash A.", 7,7, -4,4, 6,6, -2,2],
 ["Uzair T.", 3,3, -2,2, 0,0,  0, 0],
 ["Mathew R.", 6,6, -3,3, 6,6,  0, 0]
  ]);


    var options = {
 
 seriesType: 'bars',
    bars: "vertical",
    isStacked: 'true',
    height: 500,
 
    legend: {
      position: "top",
      alignment: "start"
    },
   
    hAxis: {
      title: '',
      textStyle: {color: '#777777', fontSize: '18', fontName: 'Overpass', bold: false},
     
    },
   
    vAxis: {
      textStyle: {color: '#fff'},
      title: '',
      gridlines: {
        color: "#eee"
      },
      viewWindow: {
        ticks: 20,
        max: 10
      }
    },
    vAxes: {
      0: {},
      1: {
        gridlines: {
          color: "transparent"
        }
      }
    },
    series: {
      0: {
   type: "bars",
         targetAxisIndex: 0,
 color: '#4285f4'
      },
      1: {
   type: "bars",
         targetAxisIndex: 0,
 color: '#93b6f3'
      },
      2: {
   type: "bars",
         targetAxisIndex: 1,
 color: '#db4437'
      },
      3: {
   type: "bars",
        targetAxisIndex: 1,
 color: '#f19a92'
      }
    },
    };


    var chart = new google.visualization.ComboChart(document.getElementById('chart_div'));
    chart.draw(data, options);
  }

Can someone help me identifying the issue in my code. I want to show annotations as well as show it in group stacked bar chart.

Sorry, but the corecharts don't support two or more side-by-side stacks, whether on the same target index or different ones.
