How to add category axis title in amcharts stock charts
<p>Here is the demo of my graph in Amcharts.<a href="http://codepen.io/RKR3/pen/xReEGx" rel="nofollow noreferrer">Working Pen</a> </p>

<p>Here I have included </p>

<pre><code>"panels": [{
        "titles": [{
              "id": "Title-1",
              "size": 15,
              "text": " Taxi State Analysis"
            }],
            "categoryAxis": {
                "title": "Time spent in Minutes",

              },
        "stockLegend": {}
      }]
</code></pre>

<p>The chart title works fine but the category axis title did not appear. I also tried </p>

<pre><code>"categoryAxesSettings": {
    "minPeriod": "mm"
    "title":"Time in minutes "
  }
</code></pre>

<p>This also did not work.Any help is appreciated.</p>
