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.

Version history
