  38 One is setting a store element into the Gauge and selecting the field to be used from that store. Another one is instanciating the
  39 visualization and using the <code>setValue</code> method to adjust the value you want.</p>
  40
  41 <p>A chart/series configuration for the Gauge visualization could look like this:</p>

  43 <pre class="prettyprint"><code>{

  60 }
  61 </code></pre>
  62

  64 setting a maximum, minimum and steps configuration options into the axis. The Gauge series configuration contains the store field to be bound to
  65 the visual display and the color set to be used with the visualization.</p>

 228 A delayed, one-time listener.
 229 <pre><code>myPanel.on('hide', this.handleClick, this, {

 239     mouseover: this.onMouseOver,
 240     mouseout: this.onMouseOut,
