How to reduce the space between yaxis points with highcharts.js?
<p>I have a page where I can put in two timeintervals and after posting these two timeintervals I get the amount of sold tickets between these two dates. </p>

<p>i get back multiple data depending on how far back I go. </p>

<p><strong>My problem:</strong></p>

<p>If I go as far back as to the first insert of the database. 
I will get a high value of for example 200 tickets and after that I calculate the difference between each row in the database which gives me a chart like this: </p>

<p>As you see in the image I would like to reduce the space between the y-axis points in order to see the smaller values better. </p>

<p>In the example above I have a bar that is 160 and other bars that are for example 1 or 2 and I can hardly see them on the chart </p>

<p>Code for this:</p>

<pre><code>buildCharts: function (target, chartData, chartEnum) {

    $(target).highcharts({
        chart: {
            type: 'column',
            height: 300,
        },
        title: {
            text: chartEnum.name
        },
        xAxis: {
            type: 'category'
        },
        yAxis: {
            title: {
                text: chartEnum.text
            }
        },
        series: [{
            name: 'SystemInfo',
            showInLegend: false,
            colorByPoint: false,
            data: chartData,
            turboThreshold: chartData.length + 500

        }],
    });
}
</code></pre>

<p>How can I reduce  space between y-axis points? </p>
