Welcome to Cute Plot

Lightning-fast power systems visualisation for power system engineers

Cute Plot is a time series plotting tool designed for power systems analysis. Its goal is to make it seamless and easy to visualise the data you have, so that it's fast to diagnose problems, find insights, and visualise your simulations and site data.

Closed Beta

Cute Plot is currently in closed beta. Features, interfaces, and documentation may change as we iterate based on feedback.

Start with the Quick Start — you'll load data, plot signals, measure values, and annotate your findings in one session.

Key Features

  • Multi-format file support — load CSV, PSCAD (.inf/.out), and PSS/E files. Drag and drop files or use the file browser.
  • Interactive plotting — a subplot grid with synchronised X-axes, box zoom, pan, and scroll zoom. GPU-accelerated rendering keeps million+ point datasets smooth at 60fps.
  • Templates — save your subplot layout, series patterns, axis settings, and transformations as reusable YAML templates. Apply them to new data files with one drag.
  • Powerful search — filter series by name with wildcards, boolean logic, and value-based queries (e.g. Voltage:>1@5-10).
  • Data transformations — scale and offset series via legend sliders or template definitions. Useful for unit conversions and time alignment.
  • Query rectangle — Ctrl+drag to select a region and instantly see statistics: min, max, mean, FFT, and NER-compliant rise/settling time metrics.
  • Annotations — add horizontal reference lines (with intersection detection), vertical time markers, linked cross-subplot markers, and draggable text labels.
  • Power systems analysis — built-in NER 233 and NER 234+ calculations for rise time, settling time, recovery time, and damping ratio, with reference line overlays.
  • Screenshots — one-click capture to PNG with automatic clipboard copy.
