堆叠的水平图表。如何触发堆叠元素中的个人悬停?
Stacked horizontal chart. How to trigger individual hover in the stacked element?
我正在尝试为水平栏中堆叠的数据显示不同的工具提示。
代码来自:https://thewebdev.info/2020/08/18/chart-js%E2%80%8A-%E2%80%8Astacked-bar-chart-and-radial-chart/
var ctx = document.getElementById('myChart').getContext('2d');
var stackedBar = new Chart(ctx, {
type: 'horizontalBar',
data: {
labels: ['Red', 'Blue', 'Yellow'],
datasets: [{
label: '# of Votes',
data: [12, 19, 3],
backgroundColor: [
'rgba(255, 99, 132, 0.2)',
'rgba(54, 162, 235, 0.2)',
'rgba(255, 206, 86, 0.2)',
],
borderColor: [
'rgba(255, 99, 132, 1)',
'rgba(54, 162, 235, 1)',
'rgba(255, 206, 86, 1)',
],
borderWidth: 1
}]
},
options: {
scales: {
xAxes: [{
stacked: true
}],
yAxes: [{
stacked: true
}]
}
}
});
当我们将鼠标悬停在栏上时,无论我们悬停在哪里,它都会立即显示所有堆栈的工具提示数据。但相反,我希望堆栈元素的每个元素都有不同的工具提示。非常感谢您的帮助。
您可以为此使用工具提示模式点。
示例:
var options = {
type: 'horizontalBar',
data: {
labels: ["Red", "Blue", "Yellow", "Green", "Purple", "Orange"],
datasets: [{
label: '# of Votes',
data: [12, 19, 3, 5, 2, 3],
backgroundColor: 'red'
},
{
label: '# of Points',
data: [7, 11, 5, 8, 3, 7],
backgroundColor: 'blue'
}
]
},
options: {
tooltips: {
mode: 'point'
},
scales: {
yAxes: [{
stacked: true
}],
xAxes: [{
stacked: true
}]
}
}
}
var ctx = document.getElementById('chartJSContainer').getContext('2d');
new Chart(ctx, options);
