Graph Generator for Exam Question Setting

I was doing a sharing at the Academy of Singapore Teachers last week when a teacher asked if there was an app for creating exam-standard graphs. I recall that someone had made one before but thought I can try to do one that fits into my workflow.

Make Physics Graphs with PhysicsLens.com Graph Generator

PhysicsLens.com Graph Generator helps O Level Physics students create clear, accurate line graphs from mathematical equations. Set your axis labels, choose an x-range, and add one or more equations for different stages of motion.

Flexible graph paper

Adjust major, intermediate, and minor gridlines independently. You can choose different x- and y-axis scales, control label size, and hide any gridline level you do not need.

Equations for real motion

Each equation has its own x-range and colour. This makes it easy to model changing conditions, such as acceleration with air resistance followed by a parachute opening. The graph automatically joins equation segments at their defined endpoints.

Automatic scaling

With Auto y-scale enabled, the generator samples the plotted equations and selects an appropriate vertical range and major division size. Turn it off whenever you need a manual examination-style scale.

Ready to use

When the graph is complete, download it as a PNG image for worksheets, notes, presentations, or revision materials.
