问题 I am a newbie at Tableau (thought I have spent years working in R and Python), seems to be different in the way it handles things or I'm just not thinking the right way. I have a data sources with training data (employees training and the status). The point is to build a dashboard that shows the % of training that is overdue. I have all of the logic for it, but I am stuck on something. I have a calculated field to show me the total training due, then when I put that in a table, with a filter

问题 I have an extremely similar issue / set of data as the person from this post .. Tableau month-based bar chart for data with date range however the accepted solution doesn't realistically work for my case. They suggested making 12 calculated fields, one for each month, and pivot and display. The 2 issues I run into with this, is my data spans across 6 years 1.

问题 I have a problem with Filters. I have a dimension with the values (0, 1, 2, 3, 4, 5). I want to use this dimension as a filter, but not to let the user the option to filter out the value "0".
