您可以在所有数据集或每个数据集级别的选项根目录中将 showLine
属性 设置为 false:
const options = {
type: 'line',
data: {
labels: ["Red", "Blue", "Yellow", "Green", "Purple", "Orange"],
datasets: [{
label: '# of Votes',
data: [12, 19, 3, 5, 2, 3],
backgroundColor: 'pink'
},
{
label: '# of Points',
data: [7, 11, 5, 8, 3, 7],
backgroundColor: 'orange',
showLine: false // Hide line for only this dataset
}
]
},
options: {
showLine: false // Hide the line for all datasets
}
}
const ctx = document.getElementById('chartJSContainer').getContext('2d');
new Chart(ctx, options);
<body>
<canvas id="chartJSContainer" width="600" height="400"></canvas>
