Javascript中的条形图：堆积条形图+分组条形图

Question

我正在寻找一个Javascript解决方案，将Grouped和Stacked Bars与一个漂亮的图形混合在一起，例如Protovis提供的图形。

例如，如果我想将Apple（iPad + iPhone）设备上的下载与Android设备进行比较，我可能会（借口我糟糕的ascii艺术）

Answer 1

结帐Google Chart Tools和Google Visualization

例如，您可以指定以下内容：

cht=bvs
chco=4D89F9,C6D9FD
chd=t:10,50,60,80,40|
  50,60,100,40,20
chds=0,160

假设您将chd更改为

cht=bvs
chs=250x150
chco=4D89F9,C6D9FD
chd=t:0,50,0,80,0, 10, 50, 40
      60,0,100,0,20, 50, 100, 60
chds=0,160

看看上面的图表（好像它是一个组图，但实际上是它的堆叠）。然后，您可以在创建堆叠的“查找”组之后附加数据，如图所示。

嘿，我刚刚在d3.js上开发了分组+堆积条形图。

• Demo

Answer 3

由于目前还没有人提及C3.js，这里是一个堆叠+分组演示（source）

＆＃13;

＆＃13;

var chart = c3.generate({
    bindto: "#chart",
    data: {
        columns: [
            ['data1', -30, 200, 200, 400, -150, 250],
            ['data2', 130, 100, -100, 200, -150, 50],
            ['data3', -230, 200, 200, -300, 250, 250]
        ],
        type: 'bar',
        groups: [
            ['data1', 'data2']
        ]
    },
    grid: {
        y: {
            lines: [{value:0}]
        }
    }
});

setTimeout(function () {
    chart.groups([['data1', 'data2', 'data3']])
}, 1000);

setTimeout(function () {
    chart.load({
        columns: [['data4', 100, -50, 150, 200, -300, -100]]
    });
}, 2000);

setTimeout(function () {
    chart.groups([['data1', 'data2', 'data3', 'data4']])
}, 3000);
