Is your feature request related to a problem? Please describe. It is sometimes desirable or required to use the "stack" option on an imported dataset to make it compatible with a certain graph type. When you stack data on a given column, RawGraphs automatically names the new columns created from stacking, and there's no way to rename them. This is a problem, because these names are sometimes used in certain graphs as labels, and there's no way to edit those either.

This inability to rename columns isn't exclusive to stacked data, as you can't rename unstacked columns either, but it's especially annoying here because of the automatic renaming.

For example, with sample input like this:

Date	Score A	Score B
1/1/2000	95	73
1/2/2000	87	65
...	...	...

When stacked on the "Date" column, becomes this:

Date	column	value
1/1/2000	Score A	95
1/1/2000	Score B	73
1/2/2000	Score A	87
1/2/2000	Score B	65
...	...	...

If the "value" column gets used as axis data in a graph, then the text "value" will be imported as the label of the relevant axis, with no way to change it. I ran into this personally with a line graph:

Describe the solution you'd like I want a way to either rename columns of data in the data loader, especially generated columns of stacked data, or, more preferably, I want to be able to edit axis labels in the table customizer menu.

Describe alternatives you've considered The only workaround for the stacked data case is to stack your data outside the editor and name the columns accordingly, since you can't currently export stacked data (via #242).

Additional context I think label editing was an available feature in RawGraphs v1, it remains a really useful feature that would be great in v2.
