visualize raw output of SQL Lab query in superset
Question:
I run a simple query in SQL Lab and get the following output
SELECT timestamp, nav from account_info
I would like to visualize this "raw" output simply as a timeseries line chart.
However, when I click the visualize button, the only options I have are to perform some aggregation (counting, summing, avging, etc.).
I do not want to aggregate, I simply want to visualize the output of the sql query. Is there a way to do this?
Answers:
I believe an aggregation is indeed typically – if not always – required.
That being said, the workaround is to do a meaningless aggregation:
In your case, after clicking Visualize, check both timestamp and nav as is_dimension, check timestamp as is_date, and define agg_func as MIN(x) for nav.
Click Visualize, select Visualization Type as Time Series - Line Chart, set Metrics as min__nav and remove the Group By.
Query and you should get what I think you’re looking for.
When working with time series related visualization you will need to set up a default DATETIME field from your database table before processing.
To add main DATETIME column in superset you simply go to
Sources->tables->edit table
then set a default DATETIME column from your table.
For this you do not need to write a SQL query. Just choose the columns you want the visualization on in the table while creating slice.You can also choose time column and grain of time.
