Vizframe - Stacked column chart category axis
<p>I'm trying to create stacked column chart as on the picture attached, but I would like to remove "Effort" text highlighted in yellow. </p>

<p>The chart should display (per day) how many hours people worked on the project.</p>

<p>I have and XML view: </p>

<p>In the controller in the onInit function I tried to set vizProperties. But when I set <strong>hidSubLevels</strong> of label of categoryAxis to true, then dates disappear. I don't understand why "Effort" is displayed as category, because it is defined as measure, not category. Could someone please advise how to do such chart without category "Effort" (yellow-highlighted on the picture attached)? </p>

<pre><code>var oVizFrame = this.getView().byId("idVizFrame");
oVizFrame.setVizProperties({
  interaction: {
    behaviorType: null
  },
  plotArea: {
    dataLabel: {
      visible: false
    }
  },
  valueAxis: {
    title: {
      visible: true,
    },
  },
  categoryAxis: {
    title: {
      visible: false,
      text: 'Category text'
    },
    label: {
      hideSubLevels: false
    },
  },
  title: {
    visible: true,
    text: 'Project'
  },
  tooltip: {
    visible: true,
  }
});
