javascript - 我们可以更改选定点的样式吗?
问题描述
在这个 plotly.js 生成的箱线图中,选择点后,未选择的点的不透明度为 0.2。
是否可以更改选定点和非选定点的样式?
var trace1 = {
y: [0, 1, 2, 3, 4, 5, 6],
type: 'box',
selectedpoints : [1,2,5],
boxpoints: 'all'
};
var data = [trace1];
var layout = {};
Plotly.newPlot('myDiv', data, layout);
<head>
<!-- Plotly.js -->
<script src="https://cdn.plot.ly/plotly-latest.min.js"></script>
</head>
<body>
<!-- Plotly chart will be drawn inside this DIV -->
<div id="myDiv"></div>
<script>

</script>
</body>
解决方案
如果您查看参考,您会看到“已选择”和“未选择”标记的属性允许您更改它们的样式:
var trace1 = {
y: [0, 1, 2, 3, 4, 5, 6],
type: 'box',
selectedpoints: [1, 2, 5],
boxpoints: 'all',
selected: {
marker: {
color: '#ff0000',
opacity: 0.8
}
},
unselected: {
marker: {
color: '#00ff00',
opacity: 0.5
}
}
};
var data = [trace1];
var layout = {};
Plotly.newPlot('myDiv', data, layout);
<head>
<!-- Plotly.js -->
<script src="https://cdn.plot.ly/plotly-latest.min.js"></script>
</head>
<body>
<!-- Plotly chart will be drawn inside this DIV -->
<div id="myDiv"></div>
<script>

</script>
</body>
