Matrix: Conditional formatting on blank cells

yes when you applying a conditional formating theres a option to apply by a measure or value on that selected field, and another option to apply the format to blank values also. 

in your matrix measure values, create a "if" condition for a blank values and with values <> blank, create a varaibles with colors anda aply to condicional filed.
measure =
var blankvalues = "black"
var nonblankvalues = "green"
if(
tableWithValues <> Blank,
nonblankvalues,
blankvalues,
)
you can use this for more option in your condition, like, tableWithvalue >= 2, "red" etc...

Hi abpgupta,

You need to confirm these blank parts have corresponded records in your table.
If they mean these records not include in your table, you need to create a category table of the field which not include all values and uses them on your matrix.
Then you can write a measure formula to check the current category and look up raw table records and return specific results for conditional formatting.
