Chart.JS -工具提示-问题:3个数据点，每个数据点都显示三个单独的工具提示
Chart.JS -工具提示-问题:3个数据点，每个数据点都显示三个单独的工具提示
提问于 2020-09-23 14:49:13
我为我们的组制作了一个小仪表板，用户希望在条形图上悬停以获得不同实现阶段的定义。我有悬停的部分要做，但我正在清理遗漏的东西。所有三个工具提示显示每个数据点。我有三个数据点:无实现、预实现和实现/维持。因此，我有三个定义。然而，这三个定义都显示在一个数据点上。例如:在“无实现”(No Implementation )上方，有人看到“无实现定义”、“预实现定义”和“实现定义”。它应该只显示“无实现定义”。
我肯定这是个简单的解决办法，而且我只是忽略了一些事情。任何帮助都是非常感谢的。这是代码库，下面是我的代码。Codepen：https://codepen.io/tenebris_silentio/pen/GRZPedx

将info作为数组的数组，.Instead只需拥有[ ]单个数组，然后为单个图片组获取info数组，如下面的data.datasets[tooltipItems[0].datasetIndex].info[tooltipItems[0].index]。
演示代码：
//bar chart
var bar = document.getElementById('bar');
var barConfig = new Chart(bar, {
type: 'bar',
data: {
labels: ['Implementation not part of objectives', 'Pre-Implementation', 'Implementation/Sustainment'],
datasets: [{
label: '# of data',
data: [30, 25, 20],
info: [
'No Implemention Definition', 'Pre-Implementation Definition', 'Implementation Definition'
],//simply have array
backgroundColor: ['rgba(0, 0, 89)', 'rgba(0, 0, 89)', 'rgba(0, 0, 89)'],
borderWidth: 1
}]
},
options: {
tooltips: {
callbacks: {
title: (tooltipItems, data) => data.labels[tooltipItems[0].index],
label: (tooltipItems, data) => data.datasets[tooltipItems.datasetIndex].label + ' ' + data.datasets[tooltipItems.datasetIndex].data[tooltipItems.index],
footer: (tooltipItems, data) => 'Description:' + (data.datasets[tooltipItems[0].datasetIndex].info[tooltipItems[0].index])
}
},
legend: {
display: false,
},
scales: {
yAxes: [{
ticks: {
beginAtZero: true
}
}]
},
responsive: true, // Instruct chart js to respond nicely.
maintainAspectRatio: false, // Add to prevent default behaviour of full-width/height
