LGraph 1.0

LGraph by L-CARD is a lightweight application for acquiring, visualizing, and recording signals from L-CARD measurement and data acquisition hardware. It helps engineers, researchers, and technicians plot multiple channels in real time, adjust scales and units, place cursors to measure timing and amplitude, and view basic statistics over selected intervals. Sessions can be saved and exported to common file formats for further analysis and reporting. With a clean interface and tight integration with L-CARD devices, LGraph reduces setup time and eliminates the need to write custom code for routine measurements—ideal for lab experiments, bench diagnostics, and production testing.

Key capabilities:

• Real-time multi-channel plotting of time-series data
• Flexible axis scaling, grids, and annotations for clear visualization
• Measurement cursors and basic metrics (min, max, average) on selected ranges
• Data logging and export to common formats for external analysis
• Playback of recorded sessions for offline review
• Seamless operation with L-CARD DAQ and measurement hardware

If you’d like a shorter or more technical version, I can tailor it to your audience.
