Round Stock Chart y Axis data points to two decimal digits

[mk.developer]

I have two questions:

1) How can I round / truncate Stock Chart Y axis in Angular?

2) The date line shows date as "Thursday, Jun 27, 23: 00". How can I format it to show the date in dd/mm/yyyy format?

Please see attached screenshot circled in blue colour.

Code: Select all

chartOptions: any = {
    credits: {
      enabled: false
    },
    chart: {
      type: 'line',
      zoomType: 'x'
    },
    title: {
      text: null,
    },
    subtitle: {
      text: null,
    },
    xAxis: {
      type: 'datetime'
    },
    yAxis: {
      title: {
        text: 'Cumulative Return'
      },
      labels: {
        formatter: function () {
          return this.value * 100;
        }
      }
    },
    legend: {
      enabled: true
    },
    tooltip: {
      pointFormatter: function () {
        return '<b>' + this.series.name + '</b>: ' + Highcharts.numberFormat(this.y * 100, 2);
      }
    },
    plotOptions: {
      series: {
        marker: {
          enabled: false
        }
      }
    },
    series: [{},{}]
  };

Thanks.

Hello mk.developer,

Thanks for contacting us with your question.

1) To round / truncate values for Y axis labels you should use yAxis.labels.format API option, or formatter for more complex changes.
Demo: https://jsfiddle.net/BlackLabel/qy2pagxh/
API reference: https://api.highcharts.com/highstock/yA ... els.format,
https://www.highcharts.com/docs/chart-c ... formatting
https://api.highcharts.com/highstock/yA ... .formatter

2) Here you can learn more about date format and supported format keys: https://api.highcharts.com/class-refere ... dateFormat Element that you want to change is tooltip header and to adjust date format you should use tooltip.headerFormat API option.

Let me know if that was what you were looking for!
