How do velocity and angle relate in projectile motion graphs?

[strawberry_sc]

can you help me relate velocity and angle in a graph? please, how are they related?
how is it possible to plot velocity vs angle given that at every (v,theta) a corresponding range is set?

im sorry. i hope you understood.
im from japan. i have physics class.

Just find the component of velocity in the x direction using the cosine of the velocity vector and the time down range.
