Tracy, thanks for keeping this TDT thing going!
- Data Blending (including Custom SQLs) is high on my list!
- Actions would be nice, if there are some advance techniques (?), (I think most of us are treating TDT as a 'Master Class' so I'm thinking it needs to be some Jedi action tricks/insights!).
- Tracy, you know I am personally a big proponent of pushing the envelope on b.g. images, but at the moment they are a bit broken, so this might be better left for latter.
- I would suggest 'formatting', but I suspect this is being reworked even as I write this
The Tableau Calculated Fields Language!
This is the thing I find most mysterious (undocumented) about Tableau. Recently someone asked on the forums what language Tableau used for calculated fields; essentially the answer was, "their own". I just had the wonderful opportunity to watch Joe Mako deconstruct (and reconstruct) one of my workbooks! He used a lot of field/table calculations and syntax that I never knew were possible. Other than trial and error, how would you know that 'NOT' works? Or that != works the same as <>? Or that the Boolean field you just placed in an IF statement doesn't have to be declared equal to anything to produce a result?
Tracy, I guess my vote is for a TDT on Tableau's calculated field syntax/language.
So many good ideas to choose from.
Shawn - A calculated field syntax/language breakdown session is a great idea. I'm actually thinking it might even be really fun to rope in one of the developers here at Tableau for a discussion like that. Not sure I could arrange that by TDT #3 though.
The advanced session on actions, however, could be reaaaaaalllly cool and is definitely something that could happen by next Thursday. There are some Jedi tricks floating around that I'm not sure have ever all been collected and talked about in a single agenda. It would be neat for me and Tracy to come to the table with the ones we know & love and likewise ask for everyone else to bring there favorites. Talk about a master class!
I like all the ideas so far... data blending would definitely be a good one, having something on how to get around needing the blend to be at a finer level of detail and then using calculated fields to generate results at the desired higher level would be good.
Performance tuning is another area that I think could be a useful discussion.
I just replied to a forum post on the very issue of data blending and thought I'd clarify, here's a post from June about using table calcs to do the aggregation when a finer level of detail is needed in the blend:
My vote is for calculation syntax, but if more time is needed to put that together I am intrigued by the possibility of advanced options - especially if these are ones I haven't seen before
+1 on the data blending discussion Jonathan presented here.
Peace and All Good!
I think we're going to go with Actions--Tips and Tricks for next Thursday. If you have any workbooks that you'd like to share, you can send them to me (tfitzgerald at tableausoftware.com) so that we can have them all in one centralized place or just prepare and have them ready for Thursday! Dustin Smith, Jeff Rice and I are going to compile a couple of the ones we have, but we'd love to get/learn more from the community as well!
The registration for our third TDT is up! It can be found here:
If you'd like to share a workbook or tricks, feel free to send them my way or have them prepared and I'll pass control over to you during the session!
See everyone Thursday!
Is the recording for the third TDT available yet?
Hi Shawn. I was looking through the TDT link, but looks like the last two videos are the only one's available to view/download. The earlier one's aren't accessible. Any ideas how/where I could get my hands on these ?
