我想在Google饼图中显示标签和百分比。有什么办法吗?在docs中,我发现可以使用pieSliceText
选项修改文本。可能的值为:
label
-显示数据名称(例如Apples
)
value
-显示绝对值(例如7
)
percentage
-显示百分比值(例如50%
)
value-and-percentage
-同时显示值和百分比(例如7 (50%)
)
但是是否有类似label-and-percentage
的东西来显示类似Apples (50%)
的东西?
答案 0 :(得分:2)
将同时显示标签和百分比的唯一配置选项是图例...
legend: {
position: 'labeled'
},
请参阅以下工作片段...
google.charts.load('current', {
packages: ['corechart']
}).then(function () {
var data = google.visualization.arrayToDataTable([
['Tasks', 'Completed'],
['Morning', 28],
['Afternoon', 43],
['Evening', 80],
['Night', 161]
]);
var options = {
width: 900,
height: 400,
title: 'Tasks Completed',
pieHole: 0.5,
colors: ['#008000', '#ffbf00', '#FF0000','#4E6282'],
pieSliceText: 'value',
sliceVisibilityThreshold :0,
fontSize: 17,
legend: {
position: 'labeled'
},
};
var chart = new google.visualization.PieChart(document.getElementById('chart_div'));
chart.draw(data, options);
});
