Combining 1-to-1 Factors in Graph Builder

[#1]

There are cases where I want to show more information on a chart and a Group field seems at first to be a logical choice, but it results in lots of white space and ruins the chart. An example using the Airline example data. In this data set, the Airline and the Carrier Code are a 1:1 relationship. But if you put them both into the Group column, it will plot all the meaningless combinations.

In the past, I have always concatenated columns to get around this problem. But it would be great if there was a way to do it in GB by stacking those factors in the same grouping but not plotting every combination. If all the combinations with a null dataset could be excluded, that would solve this problem. Maybe there is a good solution to this and I should have asked a long time ago.

I'm not interested in wrapping or using pages or different dot shapes/sizes. The best view would be Airline | Carrier code right next to each other, and only show the meaningful combinations.

I think this is one of the more common issues with graph builder. Here is one wish list item I found (I would guess it isn't the only one) Graph Builder: Option to hide categories with no data . I think the best option is still to use concatenated column
