Sorry that I can't show a screen capture due to the policy --
But it's really a simple graph -- w/ just one measure (nums) on the Y-axis and http:// links (one dimension) on the X-axis. Dates (09/01/16 to 09/30/16) are brought in from excel -- either to show on X-axis or show on Tooltip (dates in Excel are already sorted correctly).
But once they are in Tableau -- no matter how the dates are sorted (even w/ manual sorting to enforce the correct order -- 9/1, 9/2, 9/3...), on X-axis or Tooltip, the dates are still displaying in a random order like 9/26, 9/6, 9/13, 9/27... -- my version of tableau is 9.3.4. What's happened? Also, why couldn't I create a dual axis on "http links and dates"? In fact, the Edit Axis option is not even available.
Thanks a lot for your expertise!
It doesn't sound like Tableau is reading your date field in as a date. I'd suggest trying to change the data type first, and if that doesn't work, maybe start going down the road of DATEPART and MAKEDATE equations.
I'd also recommend you check out this article, as we really need to see the problem to help more.
