As @wergeld said, you need to pass 0-based values to options, otherwise you won't get displayed nothing at all. For nulls it's no possible, since this doesn't have value.

Now,you need to set minPointLength, to some value (like 10), then even 0-values will be displayed as small bars. See demo:

Just to be on the same page - to display tooltip, you need point graphic, otherwise there will be no hover event for triggering tooltip to show up.


Why not make it a shared tooltip like this:

tooltip: {
    formatter: function() {
        var s = '<b>'+ this.x +'</b>';

        $.each(this.points, function(i, point) {
            s += '<br/>'+ +': '+
                point.y +'m';

        return s;
    shared: true

Demo here. Note that I have added a 0 point value. If there is no point there then there is nothing to show, right?

    name: "2012",
    data: [
        [0, 69347.35],
        [1, 120753.55],
        [2, 0],
        [12, 95050.45]
