Tooltip issue on columnrange highchart

Question

Thi picture shows a columnrange dataRange . xAxsis shows date and yAxsis shows hours but it is inverted :false . I am trying to format tooltip by updating the values like '1,2622,349.. ' as appear on tooltip . I couldn't find where this values comes from .

This is my yAxis

 yAxis: {

                type: 'datetime',
                labels: {
                    formatter: function () {
                        return Highcharts.dateFormat('%H:%M:%P', this.value);
                    }
                },

                title: {
                    text: 'Y Sside New'
                }
            },

Can anyone tell me where should I look in the chart to figure out this issue ?

Thanks

You need to use tooltip.formatter . Just write something which will change timestamps to string dates (like you did for yAxis.labels.formatter ).
