Filtering and Hiding

Joe Mako’s Order of filtering post:

A long post on global filters, action filters, etc.

Global filter across data sources (parameter with calc field to test the parameter)
http://vizwiz.blogspot.com/2012/06/create-global-filter-in-tableau-across.html

Complex sorts in table calcs
http://community.tableausoftware.com/thread/109013

use as filter is faster than quick filters

Use as filter can work on any clickable element in the view

  • Edit actions to change what they use
  • see the TCC11 – JediTricks video for some funky global filtering

(use in nursing dashboard for per-unit stuff?)

Type-in on a quick filter is used as a wildcard, to change this use a type-in parameter and then a calc field with:

[ID] == [ID Parameter]

That will return true for the one row of interest and false for everything else. Just put that on the filter shelf and select just “true” (you’ll need to set the parameter to a value that exists to have the “true” option available).

Can’t drag a filter

If a pill can’t be dragged onto the filter shelf, try converting it into a continuous.

Lookup0 to make filters work locally after all db calculations are done. Handy to filter in %ofTotal calc. #tableaujedi #TCC11

Hide happens after the data calculations. Filter happens before. Very handy to use hide in % of total calc. #tableaujedi #TCC11

Here’s a hiding link using the LOOKUP() trick:
http://community.tableausoftware.com/message/172343
File is Hide via Filter on Table Calc.twbx.zip.

Create a field called Date Filter w/value LOOKUP(ATTR([date]),0). Tableau will treat it as a date for the filter functions, but still have all data available to the calculations.

Hide (filter) rows if first column is empty

Filtering first year out of YoY calculations:

Filtering YoY to same month/day as current date:

Grabbing certain prior dates out of the data with user-selectable “filter”:

one way to filter for data within specific dates:
http://community.tableausoftware.com/thread/116985

http://community.tableausoftware.com/message/175953#175953

IF [scanDate] >=[StartDate] AND [scanDate] <= [EndDate] THEN "Keep" ELSE "Remove" END

Restrict filter options in a Quick Filter based on another Filter

Mark Jackson demonstrates a couple of options in http://community.tableausoftware.com/message/210455#210455

Can use Action Filter

Find first month in a set of data

My response to http://community.tableausoftware.com/message/177996

which is based on: http://community.tableausoftware.com/message/168597#168597
workbook is running sum of count distinct.twbx

IF TOTAL(MIN([Month of Install]))=ATTR([Month of Install]) THEN 1 ELSE 0 END

Calculation uses TOTAL which doesn’t care about sorting/addressing, so it’s a lot more bulletproof.

Another one for last date:

As an alternative to LAST()==0 from Ross Bunker in http://community.tableausoftware.com/message/178251#178251

ATTR([Order Date]) == WINDOW_MAX(ATTR([Order Date]))

Hiding certain items/dimensions in a % of total

For hiding certain items/dimensions in a % of total – e.g. PrimeCare/Non-PrimeCare/Null, just show % of total that is PrimeCare

1.     Create a calculated field called “Hide [Dimension]” with calc:

LOOKUP(MIN([dimension]),0)

results in “find my value” when the [dimension] is in the level of detail 2. Add that calc field to the level of detail 3. Create a Quick Filter on the calc field

Enjoy!

from TCC11 – JediTricks video

Using a set:

and attached workbook (upgraded so it will work with current data)

Using a simple IF statement:

A way to “filter” dates by using LOOKUP()
http://community.tableausoftware.com/thread/115403
full_running.twbx workbook, simpler solution worksheet

Create a calculated field that is LOOKUP([Date],0) and make it continuous. Put it on the filter shelf for Range of Dates and leave it at that. When the user changes the slider, the range will change.

Hide NULL values

Robert Morton with a bit on when filters might not be able to properly compute the domain: http://community.tableausoftware.com/message/215056#215056

Data source filters are not applied directly to the data that is extracted, instead are added to each query. Post from Robert Morton: http://community.tableausoftware.com/message/227815

    Last year I did the big workbook on conditional formatting to answer some really common questions on the Tableau Community Forums. One of my projects lately has been to do the same for table calculations, which are incredibly powerful, sometimes incredibly complicated, and I believe underutilized. Tableau put together a set of Top 10 Table Calculations, here’s a list I’ve compiled of the next N most-commonly useful table calculations, based on volume of questions on the forums and relative ease of construction (there’s no densification, domain padding, domain completion, or any of that stuff in this batch):

    1. Filter Without Affecting Results
    2. Filter Top N Without Affecting Results
    3. Filter 1st Time Period from Difference from Prior
    4. Sorting by a Table Calc
    5. Comparing Selected to Group
    6. Aggregating at Different Levels…
    7. …And Returning Fewer Results
    8. Filtering Out Extra Marks by Using a Duplicate on the Filters Shelf
    9. Nesting Table Calculations to Aggregate in Different Directions
    10. Performance – One Computation to Return Same Result to All Rows
    11. How Many of X Did How Much of Y
    12. Title Showing Date Range
    13. Jittering a Scatterplot
    14. Extending an Axis with an Invisible Reference Line
    15. Making a String List

    And of course, there’s a workbook with instructions! Click to view and download the next N table calculations workbook on Tableau Public or click the image below:

    9. Nesting Table Calculations

    I can’t claim to have originated any of these calculations, thanks to Ross Bunker, James Baker, Joe Mako, Andy Cotgreave, Richard Leeke, and others I’m sure I’m forgetting for their work!
