是否有办法可以禁用Chart JS图表上的一个数据集上的工具提示,并将工具提示保留在其他数据集上。这是我目前的代码:
var data = {
labels: [' . $labels . '],
datasets: [
{
label: "Portfolio Performance",
fillColor: "rgba(0,0,220,0.2)",
strokeColor: "rgba(0,220,220,1)",
pointColor: "rgba(0,0,0,1)",
pointStrokeColor: "#fff",
pointHighlightFill: "#fff",
pointHighlightStroke: "rgba(220,220,220,1)",
data: [' . $values . ']
},
{
label: "Portfolio Expendature",
fillColor: "rgba(0,0,220,0)",
strokeColor: "rgba(0,0,0,1)",
pointColor: "rgba(0,0,0,0)",
pointStrokeColor: "rgba(0,0,220,0)",
pointHighlightFill: "rgba(0,0,220,0)",
pointHighlightStroke: "rgba(220,220,220,0)",
data: [4450000,4450000,4450000,4450000,4450000]
}
]
};
var option = {
tooltipTemplate: "<%if (label){%><%=label%>: <%}%><%= \'£\' + FormatNumberBy3(Number(value).toFixed(2), \'.\' , \',\') %>",
maintainAspectRatio: false,
bezierCurve: false,
responsive: true,
scaleLabel: "<%= \'£\' + FormatNumberBy3(Number(value), \'.\' , \',\') %>"
};
var ctx = document.getElementById("graph").getContext("2d");
var myLineChart = new Chart(ctx).Line(data, option);

您可以使用自定义工具提示执行此操作(基本上您使用HTML元素而不是使用画布单独渲染工具提示)。有关折线图的示例,请参阅https://github.com/nnnick/Chart.js/blob/v1.0.2/samples/line-customTooltips.html。
在您的情况下,您可以在https://github.com/nnnick/Chart.js/blob/v1.0.2/samples/line-customTooltips.html#L68调整循环,以根据需要排除/包含数据集。

我使用自定义工具提示配置来实现此目的(此处隐藏的数据集没有&#34;收入&#34;标签):
this.myChart = new Chart(this.ctx, {
type: 'bar',
data: {
labels: labels,
datasets: [{
label: "Income",
data: data3
},
{
label: "Tax",
data: data1,
backgroundColor: "#3EAFD5"
},
{
label: "Expenses",
data: data2,
backgroundColor: "#D24B47"
}
]
},
options: {
responsive: true,
tooltips: {
custom: function(tooltipModel) {
if (tooltipModel.body && tooltipModel.body[0].lines && tooltipModel.body[0].lines[0].indexOf("Income") == -1) {
tooltipModel.opacity = 0;
}
}
}
}
}
