When querying data in OpenTSDB, you want to view things three ways. You want to be able to see data across all combinations of tags and tag values (tag1=*, tag2=*), data across just one tag and tag value (tag=foo), or data aggregating all those together. tsdash only allows you to plot the first two.

For example, say you have the following time series:

mymetric 1234 5 host=prod1 dc=ca
mymetric 1345 6 host=prod2 dc=va

The UI will not let me see a query of just "mymetric" aggregated across all hosts and all DCs. It forces you to display separate dc=* plots, or to select a particular DC.

There probably be something like a blank entry and a "*" entry added to the dropdown menus for the tagv in the UI.
