ViewPoint

ViewPoint is a high-performance, professional-grade serial data visualization platform that lets engineers, researchers, educators, and hobbyists see complex, real-time signals clearly, at full speed, without compromise.

The app is structured around deterministic streaming, protocol-driven configuration, and rendering modes designed for real measurement and experimentation workflows that are comparable to those seen with high-performance test equipment.

At a practical level, ViewPoint gives a user one tool to:

• connect to embedded targets over serial communications (typically USB),
• configure plot behavior from firmware or UI,
• visualize real-time data in multiple domain-appropriate modes (time, XY, polar, persistence, spectrogram, color-gradient),
• locate and inspect peaks and harmonics with marker tools,
• derive traces (moving average and min/max-hold),
• and capture both raw datasets (CSV) and presentation artifacts (screenshots/screen recordings).

 Core Differentiators

• Designed for high-speed serial data, not just visual logging.
• Built for research, learning, experimentation, and teaching.
• Low-cost and designed for ongoing improvement and addition of features.
• Hardware-agnostic serial integration with protocol versioning.
• Scales from classroom demos to multi-plot research dashboards.

Modes and Feature Set

Plot Type Modes

• Cartesian: time/sample-index style plotting.
• Scatter (XY): paired-value plotting for constellations, phase, or trajectory analysis.
• Polar: radial/angular plotting for directional and rotational systems.

Update Modes

• Continuous (“strip chart”): streaming updates, suitable for live monitoring.
• Frames: packet/frame-based updates, suitable for FFTs and bounded windows.

Display Modes

• None: standard line/scatter rendering.
• Persistence: phosphor-style accumulation and decay for variation/stability visualization.
• Spectrogram: waterfall/time-frequency rendering with selectable color map and decimation controls
• Gradient: digital intensity accumulation with configurable decay.

Analysis Tools

ViewPoint includes live trace statistics, reference lines and bands, crossing feedback, derived traces, and several live marker modes.

Marker Modes

• Standard: manual and peak-locked markers on selected traces.
• Delta: compare the delta between two markers on the selected trace.
• Harmonic: fundamental selection plus harmonic search and generation.
• Spanning: synchronized marker position across multiple plots.
