[Solved]-Emulating multiple click functions or have separate clicked values based on specific areas below or above dataMin and dataMax - highcharts-Highcharts

I made a very basic example showing how to get to the values you need. The actual code and logic should not be too hard to figure out from here.

The following code will give you clicked yValue, and the current extreme values in the console. Working fiddle

chart: {
    events: {
        click: function (event) {
            console.log(event.yAxis[0].value);
            console.log(chart.yAxis[0].getExtremes());
            this.update({yAxis: {max: event.yAxis[0].value}}) 
        }
    }
}

To explain a bit more:

event.yAxis[0].value gives the yValue according to the yAxis, see API on chart.events.click.

chart.yAxis[0].getExtremes() gives the yAxis extremes, both the graph area extremes and the data(points) extremes, see API on Axis.getExtremes

this.update this refers to the chart, update lets you update whatever you may want to on the chart, see API on Chart.update. Here we use it to set the yAxis max to the value of the location clicked.
