Tooltip not showing on Android but on iOS it does.

[adaryabegi]

Hello!

I have a ChartView which actually worked really good until I saw that the tooltip for the graphs are only showing on iOS and on android not.

I think it may has something todo with overflow or so. Please help!

Edited: I found out that the tooltip.formatter function gets not executed on android. Somebody know why? (I have tested it with alerts, on iOS i got an alert, on android I did not)

Code: ` var Highcharts = "Highcharts"; var conf = { chart: { type: "line", // zoomType: "xy", renderTo: "container", ignoreHiddenSeries: false, animation: Highcharts.svg, // don't animate in old IE marginRight: 10, events: { click: function () { this.series.chart; this.series.chart.update({ tooltip: { enabled: tooltipEnabled, }, }); tooltipEnabled = tooltipEnabled ? false : true; }, }, },

title: {
  text: "",
},
xAxis: {
  type: "datetime",
  tickPixelInterval: 150,
  dateTimeLabelFormats: {
    millisecond: "%H:%M",
    second: "%H:%M",
    minute: "%H:%M",
    hour: "%H:%M",
    day: "%e. %b",
    week: "%e. %b",
    month: "%b '%y",
    year: "%Y",
  },
},
yAxis: {
  title: {
    text: "",
  },

  plotLines: [
    {
      value: 0,
      width: 1,

    },
  ],
},

tooltip: {
  formatter: function () {
    //formatter generell nicht showing
    alert("clicked");
    if (this.point.bemerkung !== undefined && this.point.bemerkung !== "") {
      const date = new Date(this.point.x);

      return (
        "<b>" +
        this.point.y.toFixed(2) +
        "</b><br/>" +
        this.series.name +
        "<br/>" +
        date.toLocaleString("de-AT") +
        "<br/>" +
        "Bemerkung: " +
        this.point.bemerkung
      );
    } else {
      const date = new Date(this.x);

      return (
        "<b>" +
        this.point.y.toFixed(2) +
        "</b><br/>" +
        this.series.a +
