X-axis:

CallPut

Delta (Δ)

Rate of change of option price per $1 move in the underlying

Gamma (Γ)

Rate of change of Delta per $1 move — identical for calls and puts

Theta (Θ)

Daily time decay — how much the option loses per day

Vega (ν)

Sensitivity to IV — dollar change per 1% IV move, identical for calls and puts

Tip — DTE slider: Drag Days to Expiry down toward 1. Watch Gamma spike ATM (binary at expiry), Theta accelerate (decay accelerates), and Vega collapse (IV sensitivity drops near expiry).

Tip — Call vs Put: Delta is the main difference. Call Delta is always positive; Put Delta always negative. Gamma and Vega are identical for both — they share the same price sensitivity to movement and volatility.
