Creating fill rate % for warehousing

Hi,

I am creating KPI's for my warehouse and have been stuck for a while on the DAX coding for my fill rate KPI.

I have 3 warehouse zones: samples, labels and other. I would like to create 3 seperate 'gauges' which show the fill % of my warehouse locations. I wanted to do this by doing a measure count if but not sure how to proceed..

Any help?

Thank you in advance...

Let's take the following example:

Material        Type                  Stock?

1                    Samples              Yes

2                    Samples              Yes

3                    Labels                 No

4                    Other                  No

5                    Other                  Yes

6                    Other                  Yes

7                    Samples              No

8                    Samples              Yes

9                    Labels                  No

10                  Other                  No

Which measures do I create and how do I link them with my gauge?
