The whole manual, the same one built into BigData for Windows. Pick a topic, or search it.
Getting started
What BigData is, where it runs, and the first five minutes from a log file to a graph.
Installing BigData for Windows
Downloading the beta, getting past the Windows warning, signing in, updates, and where your things are kept.
Opening logs
Every way a log gets in, what happens while it opens, the size limits, and what to do when one will not.
Supported formats
Which files open, which need an export first, and the quirks of each tool.
The screen, part by part
What every area is for, including the two different controls both called Layout.
The channel list
Finding channels, favorites, folding the sections, putting them on graphs, smoothing, and what each glyph means.
Graphs
Panels, cards, zooming, dragging past the end of a log, the legend, per-channel axis ranges, race zero and comparing.
Gauges and dashboards
The built-in clusters, editing a gauge, and building your own dashboard from the palette.
Histograms
Tuning tables over your log: building one, filtering it, reading a cell, paging it, and getting the numbers out.
Math channels
Making a channel the log does not contain, and using it everywhere a real one works.
Smoothing and filtering
Three things with similar names. Which one you want, and what each actually changes.
Estimated acceleration
G, chassis speed and wheel slip worked out from a log with no accelerometer.
Layouts and saved gauges
What a layout remembers, how saving works, and how it follows your account.
History
The list of logs you have opened, on this PC and across your devices.
The library
Gauge dashboards and histograms shared between tuners.
Free and Pro
Exactly what a membership adds, what the apps require, and what happens when you are offline.
Keyboard and mouse
Every shortcut and gesture in one place.
Troubleshooting
The things that go wrong most often, and the differences that look like bugs but are not.
