      If the chart onSelection event is registered. The reset zoom button will be invalid.

      example code as below:

      view

       
      <window apply="demo.line.LineTimeSeriesComposer">
          <charts id="chart" zoomType="x" spacingRight="20" 
              title="USD to EUR exchange rate from 2006 through 2008"
              subtitle="Click and drag in the plot area to zoom in">
              </charts>
      </window>
