I am trying to create a model where users (executive team) can visualise the effect of a targeted salary increase for which they (users) can modify the %. In essence, the Power BI end user (the management team) can select a random value for the salary increase and the Power BI model will show the appropriate results (additional cost, employees affected, etc.) without going behind the scene. The salary increase could be any randon number between zero and 10%. I hope my question makes sense.
Unfortunately, I don't believe that there are any options that you are going to like. Parameters are now supported in queries, so that might be one route, but you probably do not want your users having to run the query and enter the % increase just to get the answer. If I understand your question correctly, you would like the user from the dashboard or report level to be able to enter a number and have the visuals reflect that. There is no "user input" at the report/dashboard level of which I am aware. Would make a nice "Idea" if it does not already exist.
I will try to replicate it. However, I was thinking of something more flexible like any value from 0 to 10, so for example 3.77%, Using your idea, I will have to develop a table that contains all possible values between 0 and 10 and on the slicer they would not look visually appealing. Would it be possible to have a sliding slicer? I think I've seen the concept of sliding data on a time table type of visual. Does anybody know how to make it happen?
