An interactive Python/Plotly tool for loading, cleaning, and visualizing multichannel time-series data (e.g., EEG, ECG).
The viewer supports dual y-axes to handle different signal scales, a scrollable/zoomable timeline, and flexible channel selection.
- Load CSV data with optional metadata lines (
#) automatically skipped. - Plot EEG signals (µV) on the left y-axis.
- Plot ECG/CM signals (mV) on the right y-axis.
- Interactive timeline with scroll and zoom controls.
- Support for varying datasets (handles missing channels gracefully).
- Clean and extensible design for other biosignal or time-series data.
This project was developed with the assistance of ChatGPT, which I used as a learning aid to better understand the features offered by Plotly and how to implement them. ChatGPT helped me explore different visualization options (such as dual y-axes, range sliders, and channel selection) and guided me in adapting these features to build the graph design I envisioned.
