I'm pretty sure this is because Measure Names doesn't fully act like a dimension. I'm sure what you have here is a very simplified version of your data set, but would it be possible to Pivot your measures so that they are a true dimension?
Now your Measure Names are a proper dimension - Pivot Field Names.
Replace all your Measure Names and Values with Pivot Field Names and Values, and the Tooltip now works:
Hope this helps,
Tooltip Viz Question alt.twbx 19.4 KB
That's correct, this is a very simplified version of my data set (I have sensitive data that I can't just send to the community or I totally would haha). I've just tried pivoting my three fields in question, but for some reason I don't have that option. The menu looks exactly like yours, and it's literally just missing the pivot option.
I'm poking around my data table, and there's no indication as to these measures being anything other than a number of hours (per type, exactly as I have it in the sample that I've provided). I think if I can get to that pivot option, the solution you showed me should be exactly what I need.
Question now is, would you know why I don't have the pivot option? Thanks very much for your help!
From the Tableau online help it appears that the PIVOT option is limited to the following data source types:
When working with Microsoft Excel, text file, Google Sheets, and .pdf data sources, you can pivot your data from crosstab format into columnar format. Source: http://onlinehelp.tableau.com/current/pro/desktop/en-us/help.htm#pivot.html?Highlight=pivot
Hope that helps clarify or point you in the right direction. Thx, Don
Thanks Don, yes, I was just looking for the list of data sources for which Pivot can be used.
Peter, it is possible to mimic the Pivot by unioning your data set to itself multiple times, one for each measure, and then adding one measure per data set. So along with your data set you'd add the columns Metric and Value, and put the values there.
But I would be interested to hear from others in the community that can think of a more streamlined way to do it with your data as is.
In one project where I used Tooltip charts extensively, I got around this by using a different chart type. I had multiple measures, but each had its own axis. So then I created multiple Tooltip chart sheets - one for each measure - and then, since each measure had its own axis and therefore its own separate Tooltip control, I could a separate Tooltip measure chart in each different measure axis.
