是的,这是可能的,您可以通过两种方式实现这一点:
null
值放在数据数组的开头:var options = {
type: 'line',
data: {
labels: [1, 2, 3, 4, 5, 6],
datasets: [{
label: '# of Votes',
data: [12, 19, 3, 5, 2, 3],
borderColor: 'pink'
},
{
label: '# of Points',
data: [{
x: 3,
y: 6
}, {
x: 4,
y: 8
}, {
x: 5,
y: 2
}, {
x: 6,
y: 12
}],
borderColor: 'orange'
},
{
label: '# of Points2',
data: [null, null, null, 9, 13, 15],
borderColor: 'lightblue'
}
]
},
options: {
scales: {
yAxes: [{
ticks: {
reverse: false
}
}]
}
}
}
var ctx = document.getElementById('chartJSContainer').getContext('2d');
new Chart(ctx, options);
<body>
<canvas id="chartJSContainer" width="600" height="400"></canvas>
<script src="https://cdnjs.cloudflare.com/ajax/libs/Chart.js/3.5.0/chart.js"></script>
</body>
您可以使用
offset
选项快速完成此操作。
示例:
const options = {
...otherChartOptions,
scales: {
x: {
offset: true
},
y: {
offset: true
}
}
};
