Examples

System Block Diagram

A signals-and-systems block diagram with framed subsystems, arrows, and an inline Fourier series equation, drawn entirely with PSTricks.

Draggable Vector

The simplest interactive diagram: a userline vector whose head follows your mouse or touch inside the frame.

Interactive

Vector Functions of the Cursor

Four userline vectors driven by functions of the cursor position — reflections, projections, and trig transforms of your pointer.

Interactive

Vectors in the Complex Plane

An interactive complex-plane diagram with a unit circle, draggable vectors, and conditional expressions controlling their motion.

Interactive

Shaded Integral with a Draggable Bound

A psplot of sin(x) whose shaded region follows a draggable uservariable — visualizing the integral as you move the bound.

Interactive

Plots Driven by Two Variables

Two uservariables driving two psplots at once — drag in the plane and watch both curves respond.

Interactive

Geometric Series with a Slider

A slider controls the number of terms N in a geometric series plot, converging toward 1/(1-α).

Interactive

Large-Scale Function Plot

A scaled psplot with custom units and axis labels.

Interactive Plot with a Variable

Two psplots coupled to a draggable uservariable with custom scaling.

Interactive

Custom Path Diagram

A pscustom path composing lines and curves into a labeled figure.

Unit Circle with Draggable Vectors

Draggable vectors constrained to the unit circle in the complex plane, with dashed projections onto the axes.

Interactive

Sampling System Diagram

A classic sampling block diagram: impulse train, ideal low-pass filter H(ω), and labeled signal paths.

Interactive Feedback System

A feedback system diagram combining frames, circles, a psplot, a userline, and four uservariables in one figure.

Interactive

A Story Told in Derivatives

A community example: a playful narrative about derivatives illustrated with sixteen psplots and five interactive variables.
