Tooltip doesn't seems to work when parent div position is relative.

[peachananr]

If I wrap the canvas with relative positioned div, the tooltip no longer show up. When I remove position:relative, the tooltip works again. Can you replicate this as well?

Thanks

I've found a solution that might help you solve this.

I replaced:

context.canvas.onmousemove = function(e) {
        if(chart.tooltips.length > 0) {
            chart.savedState = chart.savedState == null ? context.getImageData(0,0,context.canvas.width,context.canvas.height) : chart.savedState;
            var rendered = 0;
            for(var i in chart.tooltips) {
                var mx = e.x-context.canvas.offsetLeft,
                    my = e.y-context.canvas.offsetTop;
                if(chart.tooltips[i].inRange(mx,my)) {
                    chart.tooltips[i].render(mx,my);
                    rendered++;
                }
            }
            if(rendered == 0) {
                context.putImageData(chart.savedState,0,0);
            }
        }
    }

with this

function getPosition(e) {
        var xPosition = 0;
        var yPosition = 0;

        while(e) {
            xPosition += (e.offsetLeft - e.scrollLeft + e.clientLeft);
            yPosition += (e.offsetTop - e.scrollTop + e.clientTop);
            e = e.offsetParent;
        }
        return { x: xPosition, y: yPosition };
    }

    context.canvas.onmousemove = function(e) {
        if(chart.tooltips.length > 0) {
            chart.savedState = chart.savedState == null ? context.getImageData(0,0,context.canvas.width,context.canvas.height) : chart.savedState;
            var rendered = 0;
            for(var i in chart.tooltips) {
                var position = getPosition(context.canvas),
                    mx = e.x - position.x,
                    my = e.y - position.y;
                if(chart.tooltips[i].inRange(mx,my)) {
                    chart.tooltips[i].render(mx,my);
                    rendered++;
                }
            }
            if(rendered == 0) {
                context.putImageData(chart.savedState,0,0);
            }
        }
    }
