Have you ever wanted to create groupings along the x axis but not been sure how to do that?
Have you used show/hide in the Properties dialog but wanted more of a combine feature?

Guest Blog: Worm Charts

Harsh Budhiraja is a process engineer/metallurgist in Australia using Spotfire for real-time data processing and decision making. We are happy to feature him on datashoptalk as a guest blogger!

Worm Charts or (Actual vs Target Charts) are useful in a production environment where you want to see the cumulative production against planned production for a certain period. In Excel, they are easy where you have more control over things at Row level. But since the requirement was for the user to update it with date inputs, they had to be built in Spotfire with all the database connections.
