As mentioned in Looker Studio Timeline Chart No Data Bug - Q&A / Looker Studio - Google Developer forums whenever a user does the following things the message “no data” will be displayed regardless of the presence of data.
- On any dashboard with data when using any filter (textinput, selector, etc) and we reach a point where there is no data it will display as intended the “No data” message.
- But if we go back to the state where there was data it will still display the message “No Data” in the background of the Graphic
For example let’s try the next
If we apply a filter to this Dashboard and there is no data it display correctly “No data”
But if we come back and change the filter to the previous state or a state where there is data related tot he graphic, it will display the data but will have this message in the background saying “No data”
This gets solved by refreshing the page but it creates a very bad UX/UI where non techy people will get confused.
