如何从雷达图中的鼠标悬停结果中删除数据值？

Question

Currently I am working with a dynamic set of data and Chart.js. There is no standardised scale within the data I am using, so I have created a simple algorithm, for example:

3 out of 7 for question 1 [3 * (12 / 7)]
2 out of 9 for question 2 [2 * (12 / 9)]
6 out of 7 for question 3 [6 * (12 / 7)]
So that all the results for the Radar Graph are measured equally at 12.

By doing this the value is not going to be correct, even though the position of the point in respect to the rest of the graph will be.

[Label]Question 1 (3/7) : [Value]5.14

I have already included the true value in the label by combining the label with the data in the label array.

So I would like to show just the label when the mouse hovers over the spoke or dot on the chart.

Question 1 (3/7)

Is there a way of doing this without messing around with the Chart.js file?

Answer 1

Use the tooltipTemplate option

new Chart(ctx).Radar(data, {
    tooltipTemplate: "<%=label%>",
});
