NetGraph QX

Hybrid graphing calculator and real-time network/hardware telemetry terminal for Android.

Features Dual-Mode Architecture Toggle between two distinct operational modes:

1. Mathematical Function Graphing — Plot any f(x) expression in real time on a touch-interactive Cartesian grid.

2. Network & Hardware Telemetry — Live-streaming waveforms for ping latency, packet loss, CPU load, and memory pressure with color-coded status thresholds.

Three-Section Layout The screen is partitioned into three collapsible sections to make full use of the viewport:

Section Content Collapsible Canvas (40–100%) 60 FPS graph rendering with grid, curves, and coordinate tracing No Function Pad (25%) Quick-access math functions or telemetry macros Yes In-App Keypad (35%) Full QWERTY key matrix — no OS keyboard needed Yes Math Engine Expression parsing via exp4j Supported functions: sin, cos, tan, sqrt, log, ln, abs, ^ (power) Touch gestures: pan (drag), pinch-to-zoom, tap-to-trace with coordinate tooltip Telemetry Engine Coroutine-based Flow<TelemetryTick> at 250ms intervals Simulated metrics: ICMP ping latency, packet loss, CPU load, memory pressure Composite status with green/yellow/red thresholds 300-entry ring buffer for waveform rendering
