Chart.js, set a max value

问题

I am making a radar chart with Chart.js, but it only gets as big as the biggest value that's in it. I want it to be set to a standard max value, so the range is 0 to 100, and you can see how your progress is on different topics. Does anyone know how to set a max range of value to the radar chart with Chart.js?

(I tried just adding an extra dataset that's set to 100 and making it invisible, but than you see that data if you hover over the points in the radar, so that doesn't really look right)

回答1:

You can use the scaleOverride to do this, like so

...
var myChart = new Chart(ctx).Radar(data, {
    scaleOverride: true,
    scaleSteps: 5,
    scaleStepWidth: 20,
    scaleStartValue: 0,
});
