Serial Port Plotter 1.3

Serial Port Plotter by CieNTi is a lightweight, real-time graphing tool for visualizing data streamed over a serial connection. Designed for quick insight into microcontroller and sensor output, it turns lines of delimited numbers into live plots—perfect for debugging, calibration, and demonstrations.

Highlights:

• Plug-and-plot: choose a serial port, set the baud rate, and start graphing immediately.
• Multi-channel plotting: parse comma-, space-, or tab-separated values into multiple series.
• Interactive charts: zoom, pan, autoscale, and toggle series visibility.
• Customization: adjust colors, line styles, and labels to match your workflow.
• Data logging: save incoming data or captured sessions to CSV for later analysis.
• Session control: pause/resume streaming, clear plots, and reset with a click.

Typical uses:

• Visualizing sensor readings and control loops
• Firmware debugging and performance monitoring
• Classroom labs, demos, and quick experiments

Simply have your device print one line per sample with numeric values separated by a common delimiter, and Serial Port Plotter will display them as live, readable graphs.
