Issue with negative yAxis values on areachart

[jakubvojacek]

Hello @pawelfus

first of all, thank you for a great plugin!

It works out of the box almost perfectly. I am just having issues with datasets that go under zero on yAxis, attaching two samples below. One is with the plugin enabled and one with disabled.

As you can see, it does not work perfectly below zero. I would like for it to work like the first chart, just with the colors. That is to show negative elevation correctly.

Is there something that you would suggest that I do?

Thank you very much
Jakub

Hello @jakubvojacek

Thank you! It seems you've found a bug. threshold = null support seems to be missing. Temporary workaround in action: https://jsfiddle.net/BlackLabel/ou4L32cn/12/ - could you test it out and let us know the results? Thanks!

Plugin:

(function (H) {
  H.wrap(
    H.seriesTypes.coloredarea.prototype,
    "getSegmentPath",
    function (p, ...args) {
      const threshold = this.options.threshold;

      if (threshold === null) {
        this.options.threshold = this.yAxis.min;
      }

      const ret = p.apply(this, args);

      this.options.threshold = threshold;

      return ret;
    },
  )
})(Highcharts)

You are a magician! Thank you!

works like a charm ❤

Do you want me to close the issue or do you want to close it with a merge request?
