I'm currently doing an internship where I have been asked to make a few visuals in Power BI
I've searched around, tried a couple of things. But the truth is I am very much a beginner at coding and functions in general. Only had basic courses of different languages during my education and to be fair, it's a bit outside my scope of work.
So I have 2 columns I need to compare in order to find out how many dates in column 2 that is greater than the dates in column 1
So I'm imagining something like:
Measure = IF[(Investments(Expected closure)]<[(Investments(Actualclosure)]
Basically I want an overview of how many investments have a later closure date than expected.
Next thing would possibly be to create a boxplot showing the distribution (by how far we are off).
I know this is very basic, and possibly not formulated in the best way possible, please let me know if you need any more information.
Thanks in advance
You can use a calculated column as a flag to identify if actual date > expected date and then count the flag.
Flag = IF('Table'[Act] > 'Table'[Exp], 1, 0)
Hope this helps. Thanks.

Welcome to the community. Be sure to read to read this for posting questions.
For your questions, you can use the following code. You are filter the table with your logical expression with FILTER and then you count the lines of a column with COUNTA.
Measure = CALCULATE(COUNTA('Investments'[Actualclosure]),FILTER(ALL('Investments'),'Investments'[Actualclosure]>'Investments'[Expected closure]))
Hope this solves your problem.

I have a problem with Powerbi I can't seem to fix. If the answer is obvious i am sorry but i am just starting out with Powerbi.
We are trying to make a dashboard that will show if a coworker is available or not based on a code 1 -3).
We check their availability per ISOWeek. If they don't have work that week they get code 1, when they have work code 2 etc.
These codes show up the right way in SQL but when I want to add them in my matrix table and have the coworker names on the rows, the ISOWeek on the columns and then when i add the Code in values Powerbi wants to show the total, total(distinct), first or last.
The problem is it wont use the code it got per isoweek. Is there a solution for this?
Thanks in advance!
What is should look like in the matrix:
Fixed it by giving the columns: don't Summarize on the modeling tab. Then I gave the code column the minimum value for each week.
After creating a table on the report tab I need to count the number of rows that are in the table, this seems SUPER easy, right? I agree, it should be.
Well, if I add in another field into the "values" list and try to make this a "count" or "count (distinct)" type then the table's filters seem to be affected and I get different information in the table than what I had seen previously. WEIRD.
So, I need a way to count the number of rows in a table on the report tab without adding in another column to the table.
Any suggestions would be appreciated. Can provide more information if needed!
CreatedCounts =
CALCULATE(COUNT('Bugs - All history by month'[Work Item Id]),
DATESBETWEEN('Bugs - All history by month'[Created Date],
MIN('Bugs - All history by month (2)'[Iteration Start Date]),
MAX('Bugs - All history by month (2)'[Iteration End Date])))
This is what I came up with, and it works exactly as I want from what I can tell, but I don't really 100% understand WHY it works, so if anyone can provide an explanation (or better solution!) please let me know, thanks!
I'm playing around with some datasets on Kaggle.com, trying to learn better practices for ETL, as I tend to get stuck with specific things with the transform part. For this question, I am dealing with the survey results from Stack Overflow 2018: https://www.kaggle.com/stackoverflow/stack-overflow-2018-developer-survey - specifically the LanguageWorkedWith column.
Currently I am using a combination of RapidMiner/Excel to attempt to change the data. I am not well versed in R and Python code enough to solve this problem with coding methods.
The problem with the current column, is it lists all the languages that a user has chosen separated by a semi-colon. I can easily split a column on a semi-colon, but what occurs is either 2 things:
I have 31 columns of LanguageWorkedWith1 - LanguageWorkedWith31. This makes gathering a count of languages by salary to not work.
A cartesian effect where each row would be duplicated to accommodate only the choice of language. So you'll have a lot of duplicate rows, which definitely affects the integrity of the data. I have also tried using Power BI ( the Load location) to remove duplicates on the responder ID and language, but that didnt work.
Ideally I'd like to do a language by salary visual in Power BI, similar to how many kernals have it, but cant figure out the process for making this happen outside of code. Not sure how this would look exactly, but if i can split all the languages and count them, I can at least do something like this:
But I'm not sure if i can relate this back to salary with how the data is.
I just want to understand some transforming processes better! Appreciate any help!
The key here is to split into rows instead of columns.
So that you end up with a table like this:
You can keep that row expansion in its own related table in your data model so you aren't creating a giant table.
From there it's pretty easy to make visuals provided you know a little bit of DAX. For example, I created an AvgSalary measure (after converting that column to a numeric type) like this:
AvgSalary =
CALCULATE (
AVERAGE ( survey_results_public[ConvertedSalary] ),
FILTER (
survey_results_public,
survey_results_public[Respondent] IN VALUES ( 'Language'[Respondent] )
)
)
and was then able to create interesting charts like the following:
I am looking into utilising PowerBI to identify time saved due to various Projects. People will add the projects to a Sharepoint List which then feeds into PowerBI.
PROJECTs Table:
Project Tite, Desc, Hours/Month Saved, StartDate, EndDate, Repeat? (T/F)
[Some Projects only save a fixed 10 or so hours, others save time per month (indicated by the Repeat Column)]
I've created two measures, RUNTIME determining how long the project has run in months ((TodayDate - StartDate)/30) as well as TIMESAVED which is the total hours saved from that specific project (RUNTIME*Hours/Month Saved).
Whilst this works, it has a pretty big limitation. When selecting a range, say 01/01/2017 - 01/01/2018, any projects with a start date before that range are excluded. However these maybe on-going, meaning the time saved by this project during the range needs to be added.
I've attempted to find a solution to this, however I keep getting stuck at requiring the the filter dates from the slicer, however I'm not certain this is possible. I need those projects with on-going savings to have the savings during the period given to be counted as well.
Possible alternative maybe to create a Month/Year column per Month/Year with a custom formula per column to determine that projects Hours saved for that Month/Year however this seems inefficient, at that point back to Excel might be better.
Any ideas / suggestions would be greatly appreciated, currently running through any ideas to solve but keeps coming back to needing that value specified by the filter. Cheers in advance for any advice tackling this :)

Unfortunately, there is no current simple solution to this problem out-of-the-box with Power Bi. All of the slicers seem to handle dates as a single point in time. They suffer in that if you are dealing with any items that span a Start and End date (like your projects, and most of my data examples) they only take one of the dates as the input. The slicers need to accept an optional end date in our case and then perform a simple date span overlap logic to determine the items that match.
I tried to solve your problem with out-of-the-box Power Bi Desktop slicers and a custom visual Timeline Slicer I found at the store with no luck earlier this month. Out of frustration, I posted a question in the Power Bi forums for suggestions.
The final suggestion from the forums I got was to "use two Filters at Filter pane". But I am not satisfied with this answer.
The Timeline Slicer code is open source and when I get more time (ha ha), I would like to make this change to the Timeline Slicer and publish it back to the repository for everyone to use.
I will monitor this question and the forum to see if a solution emerges in the future.
You can use Timeline Storyteller. you can create your time line and add a couple Slicers for Start and End. It will split by day the dates and you won't miss any data.
I am working in a data analysis project using MS Power BI, thankfully I'm doing good work to start. However, I'm facing a little problem with DAX syntax. I come from a web development background. Anyways, my current problem is that I have rental vehicles, which can be rented from one branch and handed in at another.
I would like to compare two columns values in the same table. 'owner_branch' and 'current_branch'. Is it a good choice to create a filter with DAX? Or should I move to R Language?
If I understood your problem correct you need Calculated Column like this:
CompCol = IF ( Owner_Branch = Current_Branch, TRUE, FALSE )
as a temporary solution which I think that is not an efficient solution for a larger records in future. Anyways, my solution was creating a new column type of boolean.
