Hello,
I am dealing with a dataset for a hotel and I am trying to create a graph that shows the ramp up of reservations made for a certain date (usually a holiday).
I have created a measure (Cumulative_Count) that is supposed to count the number of cumulative reservations prior to a set date. For example, as of 6/30/19, how many reservations do I have for 7/04/19. As of now I can not get the measure to "ramp" up to the total count, it is just showing me the grand total of reservations for the target date and resulting in a flat line. I have read many threads on this topic but can not get it to work.
I have created a sample pbix file with the measure as well as a example excel document to show the expected result. They can be downloaded at this link: https://www.dropbox.com/sh/y0lvjyzcnq7iygz/AABedKjIVopWFsaHLhW9r9a4a?dl=0
Any help is much appreciated.

HI @Anonymous ,
You can download my proposed solution from here.
Here is the DAX formula I propose for it:
Cumulative_Count 2 =
var currentDate = MAX('Reservations'[res_created_at_date])
return CALCULATE(COUNTROWS(FILTER('Reservations','Reservations'[res_created_at_date]<=currentDate)), ALL('Reservations'[res_created_at_date].[Month], 'Reservations'[res_created_at_date].[MonthNo], 'Reservations'[res_created_at_date].[Day]))
Let me know if that works for you.

Thank you @lc_finance,
Yes, that formula does appear to work. Can you expand on why you used the [.Month], [.Day] tags after the columns name. Normally I only need to name the column and do not need to specify those items. Could this be why my graph does not act like other I have used? Normally I can see everyday when I move my mouse over a graph and click on the specific day to drill down. The chart in your example appears to only be able to do months.
Thank you for the continued help.
Hi @Anonymous ,
The need for specifying [.Month], [.Day] is because Power BI 'derives' multiple columns from a Date column.
These 'derived' columns are Month, Day, Year, Quarter, etc. These additional columns allow you to filter by days, month, quarter, etc when you have a Date column.
Now back to your request: as you want to show all reservations made prior to a certain date, I had to remove the filter on Dates.
If I did not remove the filter on Dates, you would see on June 15 only reservation made on June 15, on June 16 only reservation made on the 16, etc. I removed them using ALL, and I had to apply ALL to the different 'derived' columns as above.
Does this help you?

Thanks @lc_finance. Yes that helps. I did not know that about the column treatment for dates. So how would go about having a graph like the below which allows me to mouse over specific calender days to see the metrics. The x-axis still shows months and years, but I can also mouse over specific days. My current graph works different. I can only have month, quarters, days, but not all at once, which causes the graph to not be very flexible.
Thank you again for your help.
Hi @Anonymous ,
Sorry for the late reply, and I am glad that it helped you.
The chart in your screenshot is from Power BI? If yes, can you share a sample of it?
I will be happy to look into that for you,
