Could someone please explain me creating BINS based on Weekdays in Tableau? I tried creating different Calculation Fields but it won't work
You're working too hard.
Tableau already knows how to bin values by dates at many levels of granualarity: such as year, month, day, weekday, hour etc. So you don't need to create a new field to bin dates by the day of the week. (creating bins is not difficult, it's just already available in this case)
Just put a discrete (blue) date or datetime field on a shelf. You'll see the date level of granularity displayed like, say, YEAR(MyDateField) with a leading plus sign.
You can either
click on the plus sign to drill down by adding a second level, say MONTH(MyDateField)
or
right click on the field to select the date level of granularity you want
Alex's Answer is exactly correct, Tableau will perform the operation automatically. What is great about is that you can select various formats (Full day name, number, 1 letter or 3 letter day etc.).
However if you absolutely need to you can used this formula:
datepart('weekday',[Date])
to give you the 1 (Sunday) to 7 (Saturday) value if you need it for something other reason, say another calculation.

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:
I'm new of MDX and I'm trying to calculate a new measure based on two different date dimensions.
I have the Creation Date Dimension (with Year, Trimester, Month, Day) and Resolution Date (with Year, Trimester, Month, Day).As measure I have the number of tickets and I want to calculate two new measures in order to know how many tickets that were resolved this month were actually created last month and how many tickets were resolved in the same month as they were created.
I found this interesting post, but I cannot understand how to use properties..

Any ideas or suggests?
Thanks for your help.
This question cannot be answered as asked without knowing the exact definition of your time dimensions.
An approach which might be worth considering if your MDX knowledge is little, but you have some SQL knowledge and if your requirements can be fixed to just the month level as you described, could be the following, which does the main calculations already when loading the cube, and not at query time in MDX:
Add a column 'months_from_creation_to_resolution' to your fact table, possibly just add this as a column in the view you may already use on the fact table. This column would be 0 if the ticket was resolved in the same month where it was created, 1 if it was resolved in the month after creation, 2 if it was resolved e. g. in May and created in March, etc. You do this calculation using SQL date functions. You would then create a new dimension in your cube from this table, which would have the new column as the only attribute. SSAS has no problem using a table as base for both a measure group and a dimension.
Then, in MDX, the number of tickets resolved in the month they were created would just be
([Measures].[TicketCount], [Fact].[months from creation to resolution].[0])
and those resolved in the month after creation would be
([Measures].[TicketCount], [Fact].[months from creation to resolution].[1])
As a side effect, the query run time would be faster, as the main logic is pre-calculated when loading the cube.
]Difference and percent Difference must be calculated.
I cannot do Apr20-MAy20 because it is not always the same. I need to show the current month and previous month
So I did a relative filter to just show the current month and previous month.
So the difference of two columns should automatically change when the month changes.
Now how do I get the same month of prior year, how do I filter ?
I also need to calculate the difference of current year same month and previous year same month.
Thank you in advance for any help!
When I do table across difference, the difference value is overwriting the existing May and Apr month values as the below screen shot, how to show the difference in another column
Currently:
Below is Expected:
Sounds like you should create a custom filter for the dates. You want:
This month this year
This month last year
Last month this year
There are a number of ways you could do this. I'll give one example and will assume there aren't any future dates in your data set.
[DateFilter]: DATETRUNC('month',[YourDateField])>=DATETRUNC('month',DATEADD('month',-1,TODAY())) OR DATETRUNC('month',[YourDateField])=DATETRUNC('month',DATEADD('year',-1,TODAY()))
Put the to the filters shelf, set to True, and it should keep the months you want.
Then you can just use the standard table calculations to calculate Difference and Percent Difference.
Note, the formula isn't tested, just typed directly into here, let me know if it doesn't work
Based on your comments look at creating separate calculations for to YoY / MoM / etc calculation. That also means creating calculated fields to isolate the Current Month, Previous Month, etc.
For example, the current month:
[isCM]: DATETRUNC('month',[YourDateField]) = DATETRUNC('month',TODAY())
The previous month:
[isPM]: DATETRUNC('month',[YourDateField]) = DATETRUNC('month',DATEADD('month',-1,TODAY()))
Then month on month, something like:
[MoM]: (SUM([Measure])*INT([isCM]))/(SUM([Measure])*INT([isPM]))

I want to get number of months user selected using Relative Dates Filter?
If user entered "Last 3 Months" then I wants to get number of days for 3 months to use these days in another calculated field.
Calculated field which is using this is as follows.
([Total Sale within Entered Date]/[Number of Days])*365
which returns me predicted sales for the whole year.
Here, [Number of Days] is the filter which I am using. Picture added for Relative Dates filter I am using.
Screenshot of Relative Date Filter:
You need to create a calculated field that works out the number of days in the data.
Something like datediff('day',min([dates]),max([dates])) if data is present for all the days in the time period will work. This calculation will dynamically give you the number of days between the first and last date in the [dates] field for whatever data is selected by the filter (so won't be precise if not all the possible dates are represented in the dataset).
I need to filter my query with different time intervals like that:
...
where
date >= '2011-07-01' and date <='2011-09-30'
and date >='2012-07-01' and date >='2012-09-30'
I suppose such code is not good, because these dates conflicts with each other. But how to filter only these two intervals, skipping everything else? Is it even possible? Because if I query like this, I don't get any results.I tried to use BETWEEN, but it does same thing.
I bypassed this by extracting quarters from years and calculating only third quarter. But then other quarters sum is showed as zero and I can't ignore these rows that have sum column with zero value. I tried to filter where price > 0 (column where sum goes), but it says that column do not exist. So I put it whole FROM under '('')' brackets to make it calculate sum before where clause, but it still does give me error that such column do not exist.
Also if you need to see query I have now, I can post it, just tell me if it is needed.
I want to do this, because I need to compare third quarter of two different years (maybe I should use another approach).
You're not going to get any results because you can't have a date that's both within 7/1/2011 through 9/30/11 and after 7/1/2012 and after 9/30/12.
You can have a date that is either between 7/1/20122 and 9/30/2011 or between 7/1/2012 and 9/30/2012.
SELECT col1 FROM table1
WHERE date BETWEEN '7/1/2011' AND '9/30/2011' OR date BETWEEN '7/1/2012' AND '9/30/2012';
