How to Use
- 1
Start from the crossing curves
Supply and demand arrive drawn, with the equilibrium point found for you and dashed guides dropped to the price and quantity axes.
- 2
Show a shift if you need one
Switch to Demand shift and a dashed D₂ appears to the right with a second equilibrium at a higher price and quantity — the standard "increase in demand" answer.
- 3
Rename it for your market
Click the axis labels and type. Price and Quantity become Wage and Employment for a labour market, or Interest rate and Quantity of loanable funds.
- 4
Label the equilibria
E₁ and E₂ are editable, so they can match whatever notation your course uses.
- 5
Export
PNG at 1:1, free and unwatermarked. The Exam palette prints in plain black ink and photocopies cleanly.
Why Choose GraphMake?
Equilibrium, Drawn For You
The fiddly part of a supply and demand diagram is not the two lines — it is getting the intersection right and dropping clean guides to both axes so the equilibrium price and quantity can actually be read. This tool does that part, and recalculates it whenever the diagram changes.
Everything else is yours to rename. The same picture serves a goods market, a labour market, or a loanable funds market depending on what you type on the axes.
Showing a Shift in Demand
Exam questions rarely stop at equilibrium — they ask what happens when demand rises. The Demand shift diagram answers it: D₁ stays put, D₂ appears to the right, and a second equilibrium sits at a higher price and a higher quantity.
The shifted curve is drawn dashed on purpose. Printed homework is often photocopied or read in black and white, and a dashed second curve stays distinguishable from the original when colour disappears.
Frequently Asked Questions
How do I draw a supply and demand graph?
Put quantity on the horizontal axis and price on the vertical one, draw demand sloping down and supply sloping up, and mark the equilibrium where they cross. This tool starts you at that finished picture — the curves, the crossing point, and the dashed guides to both axes are already drawn, so you only rename things for your question.
What is the equilibrium point?
The point where the supply and demand curves intersect. It sets the equilibrium price and the equilibrium quantity — the only price at which the amount buyers want to buy exactly equals the amount sellers want to sell. The dashed guides on the diagram drop from that point to both axes so the two values are easy to read off.
How do I show an increase in demand?
Choose the Demand shift diagram. The original demand curve stays and a second one (D₂) appears to its right, giving a new equilibrium at both a higher price and a higher quantity. That is the standard textbook result for an increase in demand, and drawing the second curve dashed keeps it readable when printed in black and white.
Can I use this for a labour market or loanable funds diagram?
Yes. The shape is identical — only the axis names change. Click the axis labels and type Wage and Employment, or Interest rate and Quantity of loanable funds, and the same diagram answers those questions.
Can I change the curve labels from S and D?
Yes, every label on the diagram is editable in place, including the curve names, the equilibrium labels, both axes, and the title. Click the text and type.
What is the difference between a shift and a movement along the curve?
A movement along a curve is caused by a change in the price of the good itself. A shift of the whole curve is caused by anything else — income, tastes, the price of substitutes, input costs. The Demand shift diagram draws the second case, which is why a whole new curve appears rather than a new point on the old one.
