Google半甜甜圈饼图:是否可以设置总百分比?
Google halfdonut pie chart: is it possible to set total percentage?
我用 Google 个图表制作了半个圆环图,但我遇到了可见百分比总和等于 50% 的问题。有什么可能的解决办法吗?
您可以使用以下配置选项覆盖切片上显示的文本...
pieSliceText: 'value'
然后在数据中,将单元格的格式化值设置为正确的百分比...
var data = [
['Task', 'Hours'],
// use formatted values
['A', {v: 19.2, f: '38.4%'}],
['B', {v: 30.8, f: '61.6%'}],
[null, 50]
];
以下工作片段使用相同的方法,
但是计算出正确的百分比,
而不是硬编码...
google.charts.load('current', {
callback: function () {
var data = [
['Task', 'Hours'],
['A', 19.2],
['B', 30.8],
[null, 50.0]
];
var total = 0;
for (var i = 1; i < data.length; i++) {
if (data[i][0] !== null) {
total += data[i][1];
}
}
var numberFormat = new google.visualization.NumberFormat({
pattern: '#,##0.0',
suffix: '%'
});
var dataTable = google.visualization.arrayToDataTable(data);
for (var i = 0; i < dataTable.getNumberOfRows(); i++) {
if (dataTable.getValue(i, 0) !== null) {
dataTable.setFormattedValue(i, 1, numberFormat.formatValue(((dataTable.getValue(i, 1) / total) * 100)));
}
}
var chart = new google.visualization.PieChart(document.getElementById('chart_div'));
var options = {
height: 400,
chartArea: {
top: 24
},
colors: ['#8BC34A', '#64B5F6'],
legend: 'none',
pieHole: 0.4,
pieStartAngle: 270,
pieSliceText: 'value',
slices: {
2: {
color: 'transparent'
}
},
theme: 'maximized',
width: 400
};
chart.draw(dataTable, options);
},
packages: ['corechart']
});
