conditional format matrix

LauraBueno 

not sure I got it. But you can create a color measure on dimension values and measure values like this

Color Date = if(FIRSTNONBLANK(Table[date],TODAY()) <today(),"lightgreen","red")
if(FIRSTNONBLANK(Table[Value],"true") "true","green","red")


Color sales = if(AVERAGE(Sales[Sales Amount])<170,"green","red")
Color Year = if(FIRSTNONBLANK(Table[Year],2014) <=2016,"lightgreen",if(FIRSTNONBLANK(Table[Year],2014)>2018,"red","yellow"))

Color  = if(FIRSTNONBLANK(Table[Year],2014) <=2016 && AVERAGE(Sales[Sales Amount])<170 
,"lightgreen",if(FIRSTNONBLANK(Table[Year],2014)>2018,"red","yellow"))
Color sales = if([Sales Today] -[sales yesterday]>0,"green","red")

And this can be used in conditional formatting after selecting "Field". Once you use it one column , it will be there for all samples

You could achieve close to what you want by creating a rank measure that ranks within each Sample, and using that RANK measure as the value for the conditional formatting. So your table would be formatted with 4 different colour rather than a relative scale. So you could easily see which row in each column/array is the highest and lowest, but not easily see by how much they differ.

Here's one resource for RANKX, but there's lots of ways to use it, including putting it in MEASURE instead of column:

Hi LauraBueno ,

Did you choose the right field to set conditional format? You may select on the [delta vs Reference], right-click or select the down-arrow next to the field in the Values well that you want to format. Select Conditional formatting, and then select the type of formatting to apply.

For reference:

Use conditional formatting in tables
