@AhyoungRyu
Thanks for detailed review.
1. It would be nice to have some popup or feedback when conf is updated.
2. Let me hide them when panel is minimized (e.g the chart panel, the
parameter panel)
Regarding to `3. no-group field`, it's quite hard to say in just few lines.
So let me describe more.
(A) Some charts require aggregation. (= groupBy in SQL)
(B) But some charts might not need aggregation. Assume that it's already
grouped by SQL
In ultimate-line-chart, there are sub charts called `line`, `dashed`,
`step` and `no-group`.
- `line`, `dashed`,` step` uses aggregation like zeppelin's existing
charts. (similar to `PivotTransformation`)
- But `no-group` doesn't use aggregation. (similar to
`ColumnTransformation`)
