You can use custom tooltips to do this (basically you use an HTML element instead of using the canvas to render the tooltip alone). See https://github.com/nnnick/Chart.js/blob/v1.0.2/samples/line-customTooltips.html for an example for line charts.
In your case, you can adjust the loop at https://github.com/nnnick/Chart.js/blob/v1.0.2/samples/line-customTooltips.html#L68 to exclude / include the datasets as you see fit.

I make use of the custom tooltip configuration to achieve this(here it hides datasets that doesn’t have “Income” label):
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;
}
}
}
}
}
