How to read a payoff diagram
The horizontal axis is the underlying price at expiration; the vertical axis is your profit or loss in dollars, using the standard contract multiplier of 100. Where the line sits above zero the position makes money at that expiration price, and where it crosses zero is a breakeven. Kinks appear only at strikes, because each option's payoff bends exactly there and nowhere else.
Sloping end segments mean open-ended exposure: a rising final segment is unlimited profit potential, and a falling one is unlimited loss — which is why the summary panel says "Unlimited" instead of pretending the chart's edge is a boundary.
