Multiple fields into one bar graph

[Tesla8181]

Trying to work out how to have multiple columns show in one graphs Y axis.  I have a sharepoint list setup as a data source. 

In that list I have a column for various stages of a project

STAGE 1 

STAGE 2

STAGE 3

STAGE 4

Values are yes/blank under those columns

I want to be able to put those stages on a y axis of a line graph from the multiple colums to show the percentage of each stage set to yes on the one line graph. 

I am a beginner with powerbi
