Highcharts - Keep Zero Centered on Y-Axis with Negative Values

Question

I have an area chart with negative values. Nothing insanely different from the example they give, but there\'s one twist: I\'d like to keep zero centered on the Y axis.

Answer 1

Just in case someone is searching,

One option more. I ended up in a similar situation. Follows my solution:

tickPositioner: function () {
    var dataMin,
    dataMax = this.dataMax;
    var positivePositions = [], negativePositions = [];

    if(this.dataMin<0) dataMin = this.dataMin*-1;
    if(this.dataMax<0) dataMax = this.dataMax*-1;

    for (var i = 0; i <= (dataMin)+10; i+=10) {
        negativePositions.push(i*-1)
    }

    negativePositions.reverse().pop();

    for (var i = 0; i <= (dataMax)+10; i+=10) {
        positivePositions.push(i)
    }

    return negativePositions.concat(positivePositions);

},
