我有一个折线图,其数据点是圆形的,但我希望它是三角形。有没有办法做到这一点?
这是我的图表代码:
var lineChart = new Chart(ctx, {
type: 'line',
data: {
labels: ['Jan', 'Feb', 'Mar', 'Apr', 'May'],
datasets: [{
label: 'Sales Point',
data: salesData,
borderColor: bdrColor,
fill: false
}]
},
提前致谢。

为您的数据集设置pointStyle
属性为 triangle
,如下所示:
...
datasets: [{
label: 'Sales Point',
data: salesData,
borderColor: bdrColor,
fill: false,
pointStyle: 'triangle'
}]
...

var chart = new Chart(ctx, {
type: 'line',
data: {
labels: ['Jan', 'Feb', 'Mar', 'Apr', 'May'],
datasets: [{
label: 'Sales Point',
data: [3, 1, 4, 2, 5],
backgroundColor: 'rgba(0, 119, 290, 0.2)',
borderColor: 'rgba(0, 119, 290, 0.6)',
fill: false,
pointRadius: 10,
pointStyle: 'triangle'
}]
},
options: {
scales: {
yAxes: [{
ticks: {
beginAtZero: true,
stepSize: 1
}
}]
}
}
});
