It sounds like a pivot chart would give you the dynamic ability you are
looking for. If you build a Pivot table and chart you can drag the series
that you would like into the data range or have them on top to filter by.
Another option would be to use an advanced filter for your data. Using this
would also change the chart as you changed the filter.
