I'm new to tableau and I'm having trouble with the following. Here's an example of the data I'm working with.
Count | Item
___________________
1 A
3 B
2 C
3 D
5 E
2 F
5 G
9 H
I'm attempting to combine some of them together so that I may display a stacked bar chart of these groupings, as shown below:
Count | Item
___________________
6 A-C
10 D-F
14 G-H
How to do this?
