Default Profili software-Cm graphs

Hi All
I have been checking out the new Profili software and am reviewing some aerofoils for a new design.
The main data is understandable except for the graph Cm~alpha.
Can someone please explain the significance of this data to me. I am comparing three different aerofoils with the same RN.
