Hello, all.
I have a table-valued function in MSSQL that returns the
following table:
( moment DATETIME PRIMARY KEY,
[cards/day] FLOAT ,
[cycle lin] FLOAT ,
[cycle rms] FLOAT
)
Is it possible in Superset to create a dashboard with three
charts, one for the graph of each of [cards/day],
[cycle lin], and [cycle rms] vs. moment, in such a way that
Superset shall render it from a /single invocation/ of the
function, rather than redundantly invoke it for each chart?
More columns are going to be added, and when the function
contains, say, twenty columns, and takes a second to
execute, the per-chart invocation incurs a twenty-second
delay, which is redundant, because each chart is build from
the same data.
