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

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]
            ]
        }]
    });

});

To do this using HighChart in a StockChart mode, I just need to set the property tickPixelInterval.

yAxis: {
            ...
            tickPixelInterval: 35
            ...
        }
