我想在chart.js条形图上自定义工具提示。这是我的代码:
$(function () {
var barData = no_houses_person
var barOptions = {
scaleBeginAtZero: true,
scaleShowGridLines: true,
scaleGridLineColor: "rgba(0,0,0,.05)",
legend: {
display: true,
position: 'top'
},
scaleGridLineWidth: 1,
barShowStroke: true,
barStrokeWidth: 1,
barValueSpacing: 5,
barDatasetSpacing: 1,
responsive: true,
};
var ctx = document.getElementById("barChart").getContext("2d");
var myNewChart = new Chart(ctx, {
type: 'bar',
data: barData,
options: barOptions
});
});
我尝试将tooltipTemplate: "<%if (label){%><%=label%> <%}%>(<%= value %> example)",
添加到barOptions但它没有效果。

Chart.js在v2 +中从模板移动到Object interfaces,例如,如果您只想修改工具提示文本......
tooltips: {
callbacks: {
label: function(tooltipItem) {
return "$" + Number(tooltipItem.yLabel) + " and so worth it !";
}
}
}
结果:
Codepen:Chart.js Custom Tooltip
