Hello All; I'm using Tableau Desktop 9.2.8.
Goal: to display a two bar charts by date. The primary bar chart displays all values, segmented by a specific dimension (in the attached silly sample they are animals); the second "stalactite" bar chart appears directly under it, showing the results over time for that dimension.
It is important that I use Dashboard or Workbook actions (hover or select), rather than parameters.
Issue: the filtered results do not align with their reciprocal dates; instead, null dates on the end are discarded and the values are spread.
Here's what I WANT to see-- a reversed-axis second graph that allows the user to see how results varied over time...
But here's what I'm getting (more or less):
I know there's a plethora or articles about dealing with null values in dates... and the trick seems so familiar that it's bugging me (Duplicating the data source? Assigning a dummy key? Sigh...). Any words of advice?
Many thanks!
Jason Harmer kindly directed me to this link, which solved all me woes. Huzzah!
