how to set the interval of points on Y - Axis highcharts

Question

I am using highcharts for the first time, and I am trying to figure out how to set the Y axis points static.

I have used min=0 and max=140 , and the points on y axis come up as 0,25,50,75,100,125 and 150. Wherein I want it as 0,20,40,60,80,100,140.

Can someone let me know how could I achieve this.

Below is the highchart optins :

 var chart1 = new Highcharts.Chart({         chart: {             renderTo: 'Div1',             width: 600,             height: 400          },         yAxis:{             min: 0, max: 140,              lineColor: '#FF0000',             lineWidth: 1,             title: {                 text: 'Values'          },         plotLines: [{                 value: 0,                 width: 10,                 color: '#808080'             }]         },         series: [{             name: 'Value',             data: YaxisValuesArray         }]     });  });

You can set the tickInterval (http://api.highcharts.com/highstock#yAxis.tickInterval) on the axis http://jsfiddle.net/blaird/KdHME/

$(function () {     var chart1 = new Highcharts.Chart({         chart: {             renderTo: 'Div1',             width: 600,             height: 400          },          credits: {             enabled: false         },           title: {             text: 'Productivity Report',              x: -20 //center         },          xAxis: {             lineColor: '#FF0000',             categories: [1, 2, 3]         },         yAxis: {             min: 0,             max: 140,             tickInterval: 20,             lineColor: '#FF0000',             lineWidth: 1,             title: {                 text: 'Values'              },             plotLines: [{                 value: 0,                 width: 10,                 color: '#808080'             }]         },         tooltip: {             valueSuffix: ''         },         legend: {             layout: 'vertical',             align: 'right',             verticalAlign: 'middle',             borderWidth: 0         },           series: [{             name: 'Value',             data: [                 [1, 10],                 [2, 20],                 [3, 30]             ]         }]     });  });
