Renaming a Field in a Single Visualization

If you need to rename a field in a single visualization, you can simply drag the field into the visualization and then click on rename.

But what if you want to rename a field in several visualizations but not all of them.  There is a work around that can get you to this.  You need to create a new measure with a simple formula:

[New Name] = [Measure that you want to rename]

This can then be applied to any visualization that you need to use the alternative name.
