I can see my tableau dashboard on tableau desktop 2018.2 version with charts and graphs , but when i publish it on the tableau server ,I just cant see my charts . weird thing is I can see filters and parameters . my source is excel and a data source(custom sql).
Steps i followed to troubleshoot but failed
1. i am creating an extract and using it as a source , but still failed
2. upgraded my tableau desktop to match tableau server version, but failed
