是否只能在线图中显示点?我有这个基本的线图,我想隐藏线条和填充物,所以它只显示了点。
这是我的代码:
var renChart = new Chart($('#ren-chart'), {
type: 'line',
data: {
labels: ren_labels,
datasets: [{
label: 'Renovation',
data: ren_data,
backgroundColor: 'rgba(244, 81, 30, 0.5)',
borderColor: 'rgba(244, 81, 30, 0.8)',
pointBackgroundColor: 'rgba(244, 81, 30, 0.5)',
pointBorderColor: 'rgba(244, 81, 30, 0.8)',
pointRadius: 5
}]
},
options: {
scales: {
yAxes: [{
ticks: {
beginAtZero: true,
stepSize: 20
}
}]
}
}
});
对此的任何帮助将不胜感激。预先感谢。
您可以将数据集设置为 showLine
属性为 false
,这将使图表隐藏边界线(以及背景填充),仅显示数据点。
...
datasets: [{
label: 'Renovation',
data: ren_data,
backgroundColor: 'rgba(244, 81, 30, 0.5)',
borderColor: 'rgba(244, 81, 30, 0.8)',
pointBackgroundColor: 'rgba(244, 81, 30, 0.5)',
pointBorderColor: 'rgba(244, 81, 30, 0.8)',
pointRadius: 5,
showLine: false
}]
...
