【问题描述】：
我正在使用 DevExtreme 的 dxchart 迈出第一步。目前我有以下代码：
HTML：
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8" />
<title>DevExtreme Chart</title>
<!--FRAMEWOKR-->
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/2.2.3/jquery.min.js"></script>
<script src="./lib/globalize.min.js"></script>
<script src="./lib/dx.charts.js"></script>
<!--JS-->
<script type="text/javascript" src="chart.js"></script>
</head>
<body>
<div id="chartContainer" style="width:100%; height: 440px"></div>
</body>
</html>
JS：
$(document).ready(function(){
var dataSource = [
{
argument: '15.06.2016',
puls: 102,
temperatur: 37.6,
weight: 91
},
{
argument: '16.06.2016',
puls: 99,
temperatur: 35.1,
weight: 88
},
{
argument: '17.06.2016',
puls: 87,
temperatur: 38.0,
weight: 87
},
{
argument: '18.06.2016',
puls: 91,
temperatur: 36.3,
weight: 87
},
{
argument: '19.06.2016',
puls: 112,
temperatur: 37.1,
weight: 90
}
];
$("#chartContainer").dxChart({
dataSource: dataSource,
commonSeriesSettings: {
type: "spline",
label: {
visible: false,
connector: {
visible: false
}
},
argumentField: "argument",
axis: "pulsAxe"
},
tooltip: {
enabled: true,
customizeTooltip: function(obj) {
return {
text: obj.seriesName
}
}
},
legend: {
verticalAlignment: "top",
horizontalAlignment: "right"
},
"export": {
enabled: true
},
title: {
text: "Hugo Amacher | 15.08.1977 (M)",
subtitle: {
enabled: true,
text: "Ich bin ein Untertitel..."
}
},
zoomingMode: "all",
series: [
{
name: "Puls",
valueField: "puls"
},
{
name: "Temperatur",
valueField: "temperatur",
axis: "temperaturAxe"
},
{
name: "Gewicht",
valueField: "weight",
axis: "weightAxe"
}
],
valueAxis: [
{
name: "pulsAxe",
title: "Puls",
position: "left",
label: {
customizeText: function(value) {
return value.value + " bpm"
}
}
},
{
name: "temperaturAxe",
title: "Temperatur",
position: "left",
label: {
customizeText: function(value) {
return value.value + " °C"
}
}
},
{
name: "weightAxe",
title: "Gewicht",
position: "left",
label: {
customizeText: function(value) {
return value.value + " kg"
}
}
}
]
});
});
我的结果是这样的：
如您所见，有一个简单的样条图，图表上有三个不同的 y 轴和三个不同的值范围。对于每把斧头，我都有一个标签（bpm、°C 和 kg）。我还实现了 dxchart 的工具提示。在我悬停一个点的那一刻，工具提示中只有值。我还想在值之后动态添加到工具提示的标签。这意味着，当我将 ax “Puls” 的值悬停时，它应该显示例如：91 bpm。我怎样才能做到这一点。我用customizeTooltip试了一下：http://js.devexpress.com/Documentation/ApiReference/Data_Visualization_Widgets/dxChart/Configuration/tooltip/?version=16_1#customizeTooltip
我有这样的想法，检查 seriesName 并在返回中分配标签，如下所示，但它不起作用：
tooltip: {
enabled: true,
customizeTooltip: function(point) {
if (point.seriesName == "Puls") {
return {
text: point.value + " bpm"
}
} else if (point.seriesName == "Gewicht") {
return {
text: point.value + " kg"
}
} else if (point.seriesName == "Temperatur") {
return {
text: point.value + " °C"
}
}
}
},
