Tauno Serial Plotter is a graphical serial data plotting tool designed for Arduino boards and other embedded devices.
It reads incoming serial output and turns numeric values into live plots, making it useful for monitoring sensor readings, debugging microcontroller projects, and visualising changing data without building a custom dashboard.
This is free and open source software.
Key Features
- Provides a simple PyQt6 interface for plotting live serial data.
- Plots multiple variables at once with different colors for each series.
- Handles integers, floating point values, and negative numbers.
- Automatically scrolls the time scale on the X axis.
- Automatically resizes the data scale on the Y axis.
- Supports labels for data series when labels are included in the serial stream.
- Lets users adjust plot settings and export data from the graph context menu.
