  I'm trying to make a waterfall chart with Start/End year performance and contributions. I was trying to make the chart more descriptive by including a customized label, with percentage variations.</p>
  
  <p>No matter how I select the labels column, the ending Subtotal bar is independent from the others. I'm trying to customize both bottom and top labels, but I'm more concerned on the top one (the growth/loss percentage or the absolute value at the end of the year.</p>
