  <p>I generated pie chart for the GEN column which is shown below.</p>

  <p>My problem is that the pie chart is based on the number of rows. I want to get pie chart only for GEN column so that my pie chart shows only the belonging two values (1 and 2) and both occupying 50-50% of the total pie chart area.</p>
