jhettler commented on issue #4770: Cannot display Time Series Line Chart URL: https://github.com/apache/incubator-superset/issues/4770#issuecomment-379154535 Hi, I have found the similar issue yesterday on 0.24.0. In my case, we use Snowflake database and I expected it is related to DB engine and I am still not sure what's exactly wrong, everything works fine with Superset examples and as well if I add the tables from Snowflake straight from dialog Sources/Tables/Add table (plus icon in right upper corner). But if I try to create datasource/table from query it didn't work. Then I realize there are quotes around column names in query (view query menu in graph view - upper right corner). Same as in @syzuhdi case > SELECT "CITY", > "timestamp", > "count_QTY" I tried to lowercase all column names and whoila, everything works. Lowercased name of columns are not in doublequotes and it is correctly interpreted. I made following steps: 1. Run a query in SQL lab 2. Visualize it - it will ask for datasource name 3. Save the visualization 4. Go to Sources/Tables and edit the table/datasource you created in step 2 5. Rename all columns to lowercase 6. Try to visualize graph It's not nice, but it works for us as a temporary workaround. HTH.
