I have the following table with names on column 1 and various questions that are answered 'Y' or 'N' and I want to create a graph as given in the link below. I want the Ys to show up in the graph
I tried IF-ELSE calculation but it gives me the the first condition that passes and ignores the rest and my viz now has just one mark per line item.

*I've replaced the 'N' with blanks in this table here
+--------+----+----+----+----+----+----+
| Name | Q1 | Q2 | Q4 | Q5 | Q6 | Q7 |
+--------+----+----+----+----+----+----+
| Bhansa | | Y | | | | |
| Chaga | Y | Y | | | | Y |
| Chang | | | | Y | Y | |
| Cooke | | Y | | Y | | |

As user Ben mentioned, the trick here is to do a pivot. You can do that by selecting the Question columns from the data source tab and right clicking at any of the header.
Once you have pivoted the data, you can create the chart as shown below. Please note that we are using a filter on 'Pivot Field Values' to filter out the 'N' values

I have two tables products and product_attributs. One Product can have one or many attributs and these are filled by a dynamic web form (name and value inputs) added by the user as needed. For example for a drill the user could decide to add two attributs : color=blue and power=100 watts. For another product it could be 3 or more different attribus and for another it could have no special attributs.
products
| id | name | identifier | identifier_type | active
| ----------|--------------|-------------|------------------|---
| 1 | Drill | AD44 | barcode | true
| 2 | Polisher | AP211C | barcode | true
| 3 | Jackhammer | AJ2133 | barcode | false
| 4 | Screwdriver | AS4778 | RFID | true
product_attributs
|id | name | value | product_id
|----------|--------------|-------------|----------
|1 | color | blue | 1
|2 | power | 100 watts | 1
|3 | size | 40 cm | 2
|4 | energy | electrical | 3
|4 | price | 35€ | 3
so attributs could be anything which are set dynamically by the user. My need is to generate a report on CSV which contain all products with their attributs. Without a good experience in SQL I generated the following basic request :
SELECT pr.name, pr.identifier_type, pr.identifier, pr.active, att.name, att.value
FROM products as pr
LEFT JOIN product_attributs att ON pr.id = att.product_id
as you know the result will contain for the same product as many rows as attributs it has and this is not ideal for reporting. The ideal would be this :
|name | identifier_type | identifier | active | name | value | name | value
|-----------|-----------------|------------|--------|--------|-------|------ |------
|Drill | barcode | AD44 | true | color | blue | power | 100 w
|Polisher | barcode | AP211C | true | size | 40 cm | null | null
|Jackhammer | barcode | AJ2133 | true | energy | elect | price | 35 €
|Screwdriver| barcode | AS4778 | true | null | null | null | null
here I only showed a max of two attributes per product but it could be more if needed. Well I did some research and came across the pivot with crosstab function on Postgres but the problem it requests static values but this does not match my need.
thanks lot for your help and sorry for duplicates if any.
Thanks Laurenz Albe for your help. array_agg solved my problem. Here is the query if someone may be interested in :
SELECT
pr.name, pr.description, pr.identifier_type, pr.identifier,
pr.internal_identifier, pr.active,
ARRAY_TO_STRING(ARRAY_AGG (oa.name || ' = ' || oa.value),', ') attributs
FROM
products pr
LEFT JOIN product_attributs oa ON pr.id = oa.product_id
GROUP BY
pr.name, pr.description, pr.identifier_type, pr.identifier,
pr.internal_identifier, pr.active
ORDER BY
pr.name;
I calculate my metrics with SQL and publish the resulting table to Tableau Server. Afterward, use this data source to create charts and dashboards.
For one analysis, I already calculated the measures per day with SQL. When I use the resulting table in Tableau, it aggregates these measures to SUM by default. However, I don't want to have SUM or AVG of the average or SUM of the Percentiles.
What I want is the result when I don't select date dimension and not GROUP BY date in SQL as attached below.
Here is the query:
SELECT
-- date,
COUNT(DISTINCT id) AS count_of_id,
AVG(timediff_in_sec) AS avg_timediff,
PERCENTILE_CONT(0.25) WITHIN GROUP(ORDER BY timediff_in_sec) AS percentile_25,
PERCENTILE_CONT(0.50) WITHIN GROUP(ORDER BY timediff_in_sec) AS percentile_50
FROM
(
--subquery
) AS t1
-- GROUP BY date
Here are the first 10 rows of the resulting table:
+------------+--------------+-------------+---------------+---------------+
| date | avg_timediff | count_of_id | percentile_25 | percentile_50 |
+------------+--------------+-------------+---------------+---------------+
| 10/06/2020 | 61,65186364 | 22 | 8,5765 | 13,3015 |
| 11/06/2020 | 127,2913333 | 3 | 15,6045 | 17,494 |
| 12/06/2020 | 306,0348214 | 28 | 12,2565 | 17,629 |
| 13/06/2020 | 13,2664 | 5 | 11,944 | 13,862 |
| 14/06/2020 | 16,728 | 7 | 14,021 | 17,187 |
| 15/06/2020 | 398,6424595 | 37 | 11,893 | 19,271 |
| 16/06/2020 | 293,6925152 | 33 | 12,527 | 17,134 |
| 17/06/2020 | 155,6554286 | 21 | 13,452 | 16,715 |
| 18/06/2020 | 383,8101429 | 7 | 266,048 | 493,722 |

How can I achieve the desired output above?
Drag them all into the dimensions list, then they will be static dimensions. For your use you could also just drag the Date field to Rows. Aggregating 1 value, which you have for each date, returns the same value whatever the aggregation type.
I want a Cross tab that lists field values and counts them instead of just giving a count for the summation. I know I could make this with groups but I cant list the values vertically that way. From my research I believe I have to use a Display String Formula.
SQL Field Data
-------------------------------------------------
| Play # | Formation |Back Set | R/P | PLAY |
-------------------------------------------------
| 1 | TREY | FG | R | TRUCK |
-------------------------------------------------
| 2 | T | FG | R | RHINO |
-------------------------------------------------
| 3 | D | FG | P | 5 STEP |
-------------------------------------------------
| 4 | D | FG | P | 5 STEP |
-------------------------------------------------
| 5 | K JET | NG | R | DOG |
-------------------------------------------------
Desired report structure:
-----------------------------------------------------------
| Backet & Formation | Run | Pass |
-----------------------------------------------------------
| NG K JET | BULLA 1 | |
| | HELL 3 | |
-----------------------------------------------------------
| FG D | | 5 STEP 2 |
-----------------------------------------------------------
| NG K JET | DOG | |
-----------------------------------------------------------
| FG T | RHINO | |
-----------------------------------------------------------
Don't see why a Crosstab is necessary for this - especially if the entire body of the report is just that table.
Group your records by Bracket and Formation - If that's not
something natively configured in your table, make a new Formula field
and group on that.
Drop the 3 relevant fields into whichever section you need to display. (It might be a Footer, based on whether or not you want repeats
Write a formula to determine whether or not Run or Pass are displayed, and place it in their suppression field. (Good luck getting a Crosstab to do that for you! It tends to prefer 0s over blanks.)
If there's more to the report than just this table, you can cheat the system by placing your "table" into a subreport. And of course you can stretch Line objects across the sections and it will stretch to form the table outlines
I am looking at a org-mode spreadsheet formula to get the number of non-empty lines in a cell. Example :
| col1 | col2 |
|------+------|
| a | 3 |
| b | |
| c | |
| | |
|------+------|
| a | 1 |
| | |
|------+------|
| a | 2 |
| b | |
| | |
|------+------|
I have "col1" as input, and would like to fill "col2" automatically (the values can be anything, not just a b c).
Note that what you call "cell" is actually a group of cells delimited by horizontal separators (hlines).
The following example uses calc's vlen function to get the size of the vector of cells on column 1, and rows between the previous (#-I) and next (#+I) hlines.
| col1 | col2 |
|------+------|
| a | 3 |
| b | |
| c | |
| | |
|------+------|
#+TBLFM: #2$2=vlen(#-I$1..#+I$1)
You have to apply this same formula for all row groups.
I have tableau workbook online
Before, I had filter for single Principal, and applied to all CUSIPs, and I was able to plot all the inflation-adjusted principals based on Index ratios for a particular date, (refer tab Inflation-Adjusted Trend) i.e.
Now, I have multiple filters based on multiple Principals, i.e. buy one CUSIP for $1500, buy another for $900, etc (refer tab Infl-Adjusted Trend 2)
These were the columns and rows
But I do not like the format of this graph.
I wish to have all the lines together in one graph, just like the single-principal tab below ..... how to fix this? How to bring all the values into one chart?
You currently have six calculated fields calculating your inflation-adjusted principals, one for each CUSIP. Here's what that table might end up looking like:
+-----------+-------------+-------------+-------------+-------------+-----+
| CUSIP | 912828H45 P | 912828NM8 P | 912828PP9 P | 912828QV5 P | ... |
+-----------+-------------+-------------+-------------+-------------+-----+
| 912828H45 | $100 | NULL | NULL | NULL | ... |
| 912828NM8 | NULL | $455 | NULL | NULL | ... |
| 912828PP9 | NULL | NULL | $132 | NULL | ... |
| 912828QV5 | NULL | NULL | NULL | $553 | ... |
| ... | ... | ... | ... | ... | ... |
+-----------+-------------+-------------+-------------+-------------+-----|
There's definitely a better way. Your fields are set up like this:
IF [Cusip] = "912828H45"
THEN
[912828H45 Principal] * [Index Ratio]
END
Instead of setting up one field per CUSIP, make a single field that calculates that value for each CUSIP.
IF [Cusip] = "912828H45"
THEN
[912828H45 Principal] * [Index Ratio]
ELSEIF [Cusip] = "912828NM8"
THEN
[912828NM8 Principal] * [Index Ratio]
...
END
Now your table looks like this.
+-----------+------------------------------+-----+
| CUSIP | Inflation-Adjusted Principal | ... |
+-----------+------------------------------+-----+
| 912828H45 | $100 | ... |
| 912828NM8 | $455 | ... |
| 912828PP9 | $132 | ... |
| 912828QV5 | $553 | ... |
| ... | ... | ... |
+-----------+------------------------------+-----+
That's a LOT easier to work with. Drag that single field into Rows and color by [Cusip].
