+
+* will only take the first table in the output stream
+* will only use values out of the `_value` column
+* generally means you’d want to group everything into a single table (use group function, default is group_by ALL)
+* if the data you’re looking for is in a column other than `_value`, than you want to rename that column to `_value`
+* flux doesn’t let you have unbound queries so you have to have a timeframe on a query (range function). want to keep your range fairly limited.
+* you can’t use the predefined dashboard variables: time range start, stop, window. you can’t use those because they don’t exist in the context in which the query runs. only exist within the context of a dashboard.
