I'm attempting to show the results of an experiment. I'm using a calculated field and a parameter to create the following view, splitting the view by pre and post dates.
The trouble is the "Average" reference line...
None of the reference lines are placed at the actual Average for that time period (or any time period, from what I can tell). I know this because when I highlight the full date range the reference line adjusts:
Here's how I've set up the Average:
here's the calculation for post-reset (pre-reset is the same). [ reset-date ] is a hard coded parameter (the date the intervention began).
date( if [Friday Date] >= [reset-date]
then [Friday Date]
end)
Any idea what's going on here?
I was helped on the Tableau forum itself:
https://community.tableau.com/message/673000#673000
Instead of creating two date axis, I added one dimension to show pre and post.
See post at the link above for a full description, images, and a reference file.

I have a data frame with both, dates such as 2021-01-01 and times such as 11:38:17. The frame consists of 1.000 cells.
I would like to use the dynamic temporal control function to show data at a given point of date and time of day.
Unfortunately I can only animate the day. As soon as I want to change the step towards hours, I face to problem to tell QGIS where it can find the time of the data set.
Which query can I use to aggregate date and time to one column?
Thanks in advance
Use the function concat in the field calculator as follows:
concat("date", "time")
"date" — field with years and months; "time" — field with time.
In the description of the function you will see examples.
Maybe combining the columns will not be enough. To do this, you need:
Resave the layer in GeoPackage or GeoJSON (SHP does not recognize the date and time together).
Create a new field with a date and time value as follows (in the field calculator too):
— select the type of the new column "Date and time";
— in the field with the expression, write the name of the combined field. For example, "datetime".
If I understood the question correctly, then the method is.
My boss asked me to add a double slider input control for the date information on a report on Webi.
We have several columns and two of them display a date (start and end date of procedure). So I need to have two double slider, one for each date.
I've been searching for a whole day now and I know that it is not directly possible to use double slider with dates, because double slider only works with values (measures) and dates don't have that.
But I managed to create two more variables on the business layer. I used the following SQL function:
CAST(currentDate as Bigint))
These variables are displaying the date as numbers (e.g. 1090101 for 01.01.2009 (format is "dd-MM-yyyy")).
And it is working great! But it displays the dates as number, which is not possible to use for work. No one will know which date is 1090101. I could perhaps let both columns (date as date and date as number) in the report, so people could check the date they want to filter with the input control and select the right number on the slider. This could be a workaround, but not a clean one, I think.
I tried to change the format of the date as number to a date format, but then I could not use the slider anymore (even if the variable is a number).
I looked for a way to change the formatting of the values displayed on the slider, but with no luck.
So I'm asking for your help. Does anyone know how I could make this work?
Is there really no solutions for such a useful way of filtering data? I mean, filtering data by an interval of dates is surely something people want to do quite often, I assume.
Thank you in advance for your time.

You could format your date value as year, month, day and then convert it to a number so the value you are filtering on makes a little more sense. Like this...
=ToNumber(FormatDate([Your Date];"yyyyMMdd"))
It will be better than just an arbitrary number, but certainly not perfect since you will have large chunks of your range for which there never will be any corresponding data (e.g. 20211232 through 20220100).
What is wrong with just a Minimum and Maximum input controls? They are more intuitive and simple to create. Sometimes what your user or boss asks for is a bad idea and/or just not possible.
I created a rudimentary Google Form to track my win rate at Starcraft. The first column on the resulting Google Sheet is Timestamp created by the form.
I have another column that has my win-loss, and I am able to calculate my percentage for the entire sheet (all games). However, I want to be able to see my daily win rate, and I can't figure out the correct way to go about it.
I tried COUNTIF, COUNTIFS, with TODAY() and I was able to count the games for a certain day, but I don't know how to use it to tie in with my win-loss column. What I currently do is adjust my Daily formula to specify today's date before playing. I was hoping I won't need to do this.
Please see Win-Loss Stats Sheet
Solution:
You can extend your formula to compare against the date in column A:
=(COUNTIFS(D2:D, "Win", ARRAYFORMULA(INT(A2:A)),TODAY())/((COUNTIFS(D2:D, "Win",ARRAYFORMULA(INT(A2:A)),TODAY()))+(COUNTIFS(D2:D, "Loss",ARRAYFORMULA(INT(A2:A)),TODAY()))))
The additional condition would be ARRAYFORMULA(INT(A2:A)),TODAY(), which converts the timestamps into dates and compares them to today's date.
Sample Output:
Using Tableau, I need to create a visualisation that shows me the total volume of started and ended work items per day.
Typical sql data consists of columns for each:
Reference (Unique Work Item Reference)
Start Date (Date Work Item Started)
End Date (Date Work Item Finished)
For example, if on the 6th of April 2018, 55 work items were started and 5 items were finished. Each represented date should show in its own line over time.
The issue I'm getting at the moment, when I have start date as a continuous column, it calculates the number of work items started for the end date and not the number of items finished for the end date.
Any help guidance would be greatly appreciated.

This is a simple problem if you correct the shape of your data. You can achieve this by using the pivot functionality in Tableau or Custom SQL(If your data source does not support pivot).
Pivot the date columns
2. Rename the pivoted fields
Now build the view as below.(null values are due to tasks that are not yet closed, you can just filter it out)
I assume that the data is of this form Data structure
With this format, you could achieve something like this Gantt Chart
If you notice, I have created a calculated field called "Duration" which is in size shelf.
the calculated field reads
If [Status]="Finished" then
[End Date]-[Start Date] ELSE
TODAY()-[Start Date]
end
Hope this helps! Let me know if this is not clear enough
Even if the Status column is not there in the data source, it can be added using the following code
if ISNULL([End Date]) then
"WIP" else "Finished" end
Also, is this how you want to see the information?

I've been looking into making a date selector so instead of filtering by Month, Week by adding filters then displaying the quick filters to correspond. I want to be able to dynamically change the date so I can choose between Quarter, Month and Week in a single drop down.
I have made the selector part no problem it shows but when I come to my calculated field, it's not behaving how I would like.
Here is my calculated field:
CASE [Parameters].[Date Select]
WHEN 'Quarter' THEN QUARTER([Date])
WHEN 'Month' THEN MONTH([Date])
WHEN 'Week' THEN WEEK([Date])
END
This gives 2 errors...
Unknown Function QUARTER called
Unknown Function WEEK called
I am puzzled because the month one is fine.
Normally in tableau to get the month/quarter/week, I click on the Date dimension and select Month or week and it filters and displays like so: MONTH(Date).
Can anyone tell me where I'm going wrong and how I can pull the week and quarter from date in the calculated field so my selector will work.
Thanks.
There are no QUARTER and WEEK functions in Tableau, as you can see in the image below.
What you should be using to get these values are:
DATEPART('quarter',[Date])
DATEPART('week',[Date])
For filtering the date using your parameter as filter, I'll assume that you want to filter the current quarter, month or week. In this case you'll need to setup your paramaters like this:
Then you'll create a Calculated Field with the following formula:
DATEPART([Date Selector],[Date]) = DATEPART([Date Selector],TODAY())
This should give you a True/False dimension which you will use as filter for the value True. After that you should have a working parameter filtering your data accordingly to the value set.
