title: Hide zero value data labels for excel charts (with category name)
body: <p>I'm trying to hide data labels for an excel chart if the value for a category is zero. I already formatted it with a custom data label format with <code>#%;;;</code></p>
  <p><a href="https://i.stack.imgur.com/xWhLm.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/xWhLm.png" alt="Chart with format code #%;;;" /></a></p>
  <p>As you can see the data label for C4 and C5 is still visible, but I just need the category name if there is a value.</p>
  <p>Do you have any tips?</p>
