To derive a demand curve for cheese, one needs to change the price of cheese and hold other factors affecting demand constant. This is because the demand curve shows the relationship between the price of a good and the amount consumers are willing and able to purchase at each price, holding everything else constant. Changing income, tastes, or the price of other goods would shift the demand curve, but it would not allow us to derive it.
