AC-Graph

AC-Graph is the charting tool built into Qualifier. It plots recorded parameters against time, syncs them with the GPS map and any video captured alongside, and lets you drill from a fleet-level question down to the moment a signal crossed a threshold.

It works on one file at a time. When you need to prepare or export data across many files or many vehicles, use DATALAB instead. DATALAB produces files; AC-Graph produces a view.

Open it by clicking the AC-Graph icon anywhere it appears, on the Vehicles, Events, and DTC Manager pages.

Learning AC-Graph

Introduction to AC-Graph walks through the tool from the beginning:

• What is AC-Graph?, with examples of what you can build
• Open AC-Graph, from each of the pages that offer it
• Create and configure graphs, plotting a parameter and changing how it looks

Reference

• Signal Composer builds a new parameter out of existing ones, using a node-based expression editor.
• Event Timeline shows the trigger and file structure behind a trip, time-synced to the graphs below it.

For specific tasks such as thresholds, templates, axes, parameter filters, and video, see the AC-Graph group in How-To.
