You may need to create ~/.gitconfig

[alias]                                                                                                                                                   
    graph = log --graph --pretty=format:'%Cred%h%Creset -%C(yellow)%d%Creset %s %Cgreen(%cr) %C(bold blue)<%aN>%Creset'
