Is it possible to check for which point is being dragged? about g9 HOT 4 CLOSED

Although there isn't a way to check which point is being dragged (at least for now), you can get the red points to push each other by giving them both the affects list ['x1', 'x3']:

function render(data, ctx){
    var mMin = Math.min(data.x1, data.x3 - 40)
    var mMax = Math.max(data.x1 + 40, data.x3)
    var m = Math.max(Math.min(data.x2, mMax - 20), mMin + 20)
    ctx.point(m,0, {affects: ['x2']})
    ctx.point(data.x2,20, {affects: ['x2']})
    ctx.point(mMin,0, { affects: ['x1', 'x3'], fill: 'red'})
    ctx.point(mMax,0, { affects: ['x1', 'x3'], fill: 'red'})
}

Does that work for you?

Oh, I didn't realize affects works that way! The docs don't really explain that either.

But yes, that is the intended effect :)

Awesome!

I've added a more prominent note in the readme.
