I have been stuck with this issue for a while and i would appreciate some help. I have got the following table.
I would like to calculate the time by using the minimum value for each ID and subtracting it for rows that hold the same ID. However, i want the format to be in hh:mm:ss where if the difference is more than 24 hours it would be 37:44:22 for example.
Here is how i would like the results should look like.
I would prefer to do in the power query, as i tried doing something similiar in DAX, and after uploading it to power bi service the time axis isnt as expected as it assumes 00:00:00 is 12:00 AM. If done in power query the column type could be changed however.
Hi @Adham ,
Create a measure as below:
Time = var _mindate=CALCULATE(MIN('Table'[Date]),FILTER(ALL('Table'),'Table'[ID]=MAX('Table'[ID]))) var _daydiff=DATEDIFF(_mindate,MAX('Table'[Date]),HOUR) Return _daydiff&":"&FORMAT(MAX('Table'[Date])-_mindate,"nn:ss")
And you will see:
For details,pls see attachment.
Thank you for your answer. I need to plot the time as the x-axis on a line graph, and it doesnt seem possible with a measure. Is there something else i could do? Maybe alter this measure to be a column?
Hi @Adham ,
Yes,change the measure into calculated column :
_Time = var _mindate=CALCULATE(MIN('Table'[Date]),FILTER('Table','Table'[ID]=EARLIER('Table'[ID]))) var _daydiff=DATEDIFF(_mindate,'Table'[Date],HOUR) Return _daydiff&":"&FORMAT('Table'[Date]-_mindate,"nn:ss")
For modified .pbix file,pls see attached.
I actually just realised something. If you like at the table below you will see something odd when i apply the formula to have a column with the times.
|Date||Calculated Time||Should be|
When the hour in the datetime stamp hits 15 it assumes an hour has passed which is incorrect. It will assume an hour has passed all the way till 15:44:18 where the correct time is calculated and adjusted at 15:44:19. However, when the time hits 16:00:00 the calculated time difference will be 2:15:41 and so on. This trend is observed throughout the entire column. How can i fix this issue?
I have posted a question here https://community.powerbi.com/t5/Desktop/Plotting-Duration-as-continuous-line-graph/m-p/1243805#M549...
I would really appreciate if you an give me a hand.
Would it be possible to also show me the power query version of this? I want to change the type to duration, then hopefully be able to plot it on a line graph as continuous. Currently i can only plot it as categorical as this is done in dax.
