Find Maximum month from two slicers - powerbi

Question

I have this data in a pbix file:
ImaginaryData =
DATATABLE (
"Month", DATETIME,
"Amount", INTEGER,
{
{ "01 JAN 2018", 10 },
{ "01 FEB 2018", 15 },
{ "01 MAR 2018", 25 },
{ "01 APR 2018", 60 },
{ "01 MAY 2018", 55 }
}
On the canvas we have two Date field slicers:
How do I create two measures?:
Max Month Selected
Min Month Selected
I tried this for Max Month Selected but it does not work:
Max Month Selected =
Calculate(
MAX(ImaginaryData[Month]),
ImaginaryData
)

Answer 1

When two or more slicers filter the same column, you will always get the intersection of values - not the union. So in other words, if you select one value in the first slicer, and a different value in the second slicer, you would basically end up with a blank filter. That can also be seen if you drag the [Amount] column into your report:
Instead, you should use a single slicer and allowing the user to select a range of months, for example using the "Between" option:
Then, the following measures should work as expected:
Max Month Selected = MAX(ImaginaryData[Month])
Min Month Selected = MIN(ImaginaryData[Month])
If you must have two dropdown slicers, the only workaround is to create two tables, both containing the [Month] column, and have one slicer pointing to one table, and the other slicer pointing to the second table. Then, you would define your measures as:
Max Month Selected = MAX(MAX('MonthTable1'[Month]), MAX('MonthTable2'[Month]))
Min Month Selected = MIN(MIN('MonthTable1'[Month]), MIN('MonthTable2'[Month]))
