Diagramma

Diagramma dastur oynasida (1.26 rasm) dollar kursi o’zgarish rasmini chizadigan diagrammani tasvirlaydi. Dastur shunday loyixalanki, oyna o’lchamiga bog’liqmas xolda, xatto foydalanuvchi oyna o’lchamini o’zgartirgandan keyin xam, diagramma oyna markaziga joylashadi va uning katta qismini egalaydi.
