Should my data be in short format or long format to do visualization?

My data are in long format, like below, now. I am wondering should I convert it to a short format and then import it to Power BI to do the analysis and visualization? Thanks!

@jubingge , I am not very clear on the Long format. But seem like you have measure/columns/kpi as rows. If they are not too many unpivot.

Usually, we have sales, cost, and profit as columns.

But current format has its own advantage and disadvantages.

@jubingge what is your definition of short and long. Fact tables are always thin and long and dimension tables can be wide and short. 

 

I would  Kudos if my solution helped. 👉 If you can spend time posting the question, you can also make efforts to give Kudos whoever helped to solve your problem. It is a token of appreciation!

Hi, Parry2k, thanks for your reply.

 

My definition of short format is that: each indicator is in one column and each row is for each subject (ID). In other words, a subject’s repeated responses will be in a single row, and each response is in a separate column.

My definition of long format is that: as the table I showed, each subject (ID) will have data in multiple rows.
