例如我的表是这样的:
agree neutral disagree
q1 10 4 4
q2 16 1 1
q3 18 0 0
q4 15 2 1
q5 13 5 0
我想将 q1 做成一个饼图，以同意、中立和不同意作为不同的部门，对于 q2、q3 等也是如此。

注意:第一个图表成功地从我正在使用的表中提取数据。
另外两个是我试图回答我的问题的尝试。
这是我发布的代码的结果:
最佳答案
您需要为每个图表设置三个额外选项，以告知饼图应使用哪些行:
$('#container2').highcharts({
data: {
table: document.getElementById('datatable'),
switchRowsAndColumns: true, // use rows as points
startRow: 1,
endRow: 2 // use row == 2
},
chart: {
type: 'pie'
},
title: {
text: 'Data extracted from a HTML table in the page'
},
yAxis: {
allowDecimals: false,
title: {
text: 'Units'
}
},
tooltip: {
formatter: function() {
return '<b>'+ this.series.name +'</b><br/>'+
this.point.y +' '+ this.point.name.toLowerCase();
}
}
});
