Matrix conditional formatting - what is it comparing?

[s--turn]

Hello,

I'm hoping there is a simple answer to this that I've missed...  I have applied conditional formatting to the below matrix, but the colours aren't quite what I would expect.  e.g. why is 11.60% in the Region D column apparently darker than 20.43% in the Region A column? Is Power BI comparing numbers across the whole matrix, per row or per column, or something else?

I'm sure I am missing something obvious!

Thanks!

Hi @s--turn ,

The conditional format is generated based on the Field you selected, and judging from your image, you are basing it on the field [NumberOfContacts].

Here is a simple example:

If I choose to format it based on sum of the value:

Output:

If I choose the measure:

Thank you for your reply, @v-jianboli-msft . You are right - but I suppose my problem is I haven't been able to create the measure I need. If you look at my other post on this thread you will see what I mean! Any advice on that one appreciated:-)

Ah... I wonder if it's because it's basing the colours on the underlying raw figures?  Region D is much more populous than the others.  In the matrix, the measure is simply a count of individuals, but I'm displaying it as percentage of column total.  I haven't been able to create a measure which does that, which is a whole other story (I've started another thread today about that!).
