Javascript Question

Highcharts. Show only used ticks

could you help me please. How can I show only used area on the right Y-axis.

I'm need to scale the right yAxis, because the values are small (79% - 85%).

You currently have tickInterval: 0.2 and min: 0 set for your right Y-axis. If you remove these two settings, the Y-axis will scale to fit the data. See updated fiddle: I also put in a formatter for your tooltip, so that you can see the value of the percentage series properly.

tooltip: {
            pointFormatter: function(){
              return '<b>' + Highcharts.numberFormat(this.y * 100, 2)  + '%</b>'
