Usually, I would use the SSRS wizard to quickly create my table with all my fields. In this case I have to add more fields onto an existing report that has my custom formatting of each column (eg. showing/hiding columns).
So for a quick solution, I developed this ad hoc query that I can then use to pull the fields I would need to add from a view into the report. This ends up being a lot of copy & paste actions into the xml (view code) of the rdl.

@view varchar(50)
)

BEGIN

If need be, you can just create a chart with the name and color/marker sparkline and move your legend anywhere you want.
