Overlaying State Timeline Graphs

Hi all,

I am trying to overlay the Pass: false graph on top of the Pass: true graph. In areas where neither passed = true or passed = false I would like a third category to be created as “UNKNOWN”, so one single bar going across continuously with the possibility for 3 colors. Currently I have it set up by using the code feature to query a dataset with dataset{passed="true} * 0 and dataset{passed=“false”} * 1 in order to create categories for threshold coloring. However, this strategy splits the output into two bar graphs.

have you tried the concat transformation?

otherwise post a table view or csv extract of your data so we can see what is going on please?
