title: How to make percentage labels for bar graphs in Spotfire
body: <p>I'm trying to make a label for a side-by-side bar chart. The label would display the percentage corresponding to that bar. For example, if a bar represents concert ticket sales and accounts for 22% of sales in general, then the bar should display 22%. There is already an option for displaying the total number corresponding to the bar, but not a percentage.</p>
  
  <p>I would use a calculated column for this as per the example <a href="https://docs.tibco.com/pub/spotfire/6.5.3/doc/html/esc/esc_percent_of_total.htm" rel="nofollow noreferrer">here</a>, but I'm connected to external data, so I cannot use the OVER function. Any help would be greatly appreciated.</p>
