我可以从 Power BI 中的单个假设参数生成 2 个数字吗？

Question

I'm using a what-if parameter to filter a table. I'm trying to generate 2 number from this what-if parameter, as the visual "slicer" supports "between" selection and other multi-selection options.

When I change from single value selection to multi-number selection, I can't get any value on Parameter Value . When I change back to single value selection, I can get the parameter value, as seen on the pictures.

Is it possible to use the What-if parameter to generate two (or more) numbers with this multi-selection?

PS. I really need to use parameters like this, like a "between slicer", as the top and bottom numbers will be used to filter a couple of different columns with rather complex rules.

Answer 1

Yes! That's possible!

You can notice that when you create a What-if parameter, the Parameter Value measure is created with the code like:

Parameter Value = SELECTEDVALUE('Parameter'[Parameter])

The SELECTEDVALUE function returns a single value from a list, that's why no value is returned when you select multiple ones.

Knowing that, you can create measures to get the MAX and MIN value of those listed on the parameter, like this:

Top parameter = MAX('Parameter'[Parameter])

and

Bottom parameter = MIN('Parameter'[Parameter])
