即使有数据，Highchart也不显示数据范围

Question

I have line highcahrt and it displays well except one of the data range. On the same page there is a chart and grid just under the chart. and task names sorted on yAxsis and each task name has starttime and endtime . And these results displays in the grid. one of the task name let's call mytask has start and endtime in json format like others. and it dispalys it in chart js file and in grid

yAxis: {
    tickInterval: 1,
    labels: {
        formatter: function () {
            if (tasks[this.value]) {
                return tasks[this.value].name;
            }
        }
    },
}

I debugged it and I can see its name here and in series I can see it is start and end time . But I can't see datarange on chart . I checked everything but no luck

Any help appreciate

Answer 1

I resolved the issue . I is about min and max in XAxsis .

xAxis: {
                type: 'datetime',
                labels: {
                    formatter: function () {

                        var mycharttime = Highcharts.dateFormat('%H:%M:%P', this.value);

                        return timsesubstringforXaxis(mycharttime);
                    }
                },
                min: start_chart_scale_dt,
                max: end_chart_scale_dt,

                title: {
                    text: displayMonthXaxiesTitle,
                    align: 'low'
                }
            },
