Need help for a Visualization and Associated Data Modelling

Anonymous — Mon, 02 Sep 2019 18:45:48 GMT

Hi all,

I am currently working on a time series data with the following structure:

Timestamp - ID - EVENT-TYPE

EVENT-TYPE is a column used to track entries and exits and is mapped to a column with +1/-1 as values, with +1 for entry and -1 for exit. Timestamps are Hourly, Non-Unique and Irregular (There can be multiple entries and exits in an hour, and no timestamps for time periods with zero footfall, usually on weekends and during night time)

I am currently using a cumulative sum measure on this EVENT-TYPE column to visualize the total occupancy at any given time,and it's working fine.

But I also want to allow my users to select any subset of the ID's and shift their in/out times by a certain amount and then see what impact it has on the overall occupancy. I am at my wit's end on how to figure this out, especially as I am not that experienced with the whole DAX/M/PowerBI ecosystem and am really struggling on how to do this.

I would really appreciate if someone could show me how to do this in PowerBI.

Please also let me know If I have missed any crucial details, or If I am asking this in the wrong section.

Hi,

I am not sure that I took you correctly because DAX and data transformation is out of my expertise.

I can recommend the following solutions:

1. It is unclear what visuals you currently use. I recommend to check Power BI Visuals store that, as I know, contains couple of Time Series visuals

2. For advice regarding data transformation, using DAX, for instance, you should ask in this and this threads.

I have also asked this in the DAX Commands section, with more clarifications, but haven't got a reply yet.
