Statistics

Open Show Log, then choose Statistics below the revision list. The window uses the revisions currently shown in Log, excluding its working-copy row. Loading more history or refreshing Log does not change an already open Statistics window; close and reopen it to use the new list.

Choose a graph type at the top:

Statistics shows totals and activity averages/minimums/maximums.
Commits by date compares commit activity over time.
Commits by author compares commit counts.
Percent of authorship uses TortoiseGit's weighted commit/file-change measure. It is different from line ownership shown by Blame.
Changed lines including added/deleted files by date includes those files' line totals.
Changed lines not including added/deleted files by date counts changes to other files.

The initial summary avoids reading every commit's diff. Choose Calculate to load file/line totals. Authorship and line graphs start this calculation when selected. Progress appears at the bottom; Cancel stops the calculation. Closing or pressing Escape while it is running requests cancellation first.

The four checkboxes control case-sensitive author grouping, author versus committer names, commit versus author dates, and sorting by commit count versus alphabetically. Names keep their original Unicode spelling. With case-sensitive grouping, composed and decomposed spellings remain distinct even when they look the same. Disabling case sensitivity folds case without normalizing those spellings. The author slider limits individual series; remaining authors are grouped as Others. If only one author would remain, that author keeps their name. These settings and the last graph page are remembered when the window closes.

The five original graph icons select pie, stacked line, line, stacked bar and bar. Hover bars, pie wedges or line points in smaller graphs for the author, value, unit and percentage. Hovering the average region shows its value. Stacked-area polygons do not provide individual value tooltips. Zero-value intervals are omitted from bar graphs; ordinary bars share widths across the populated intervals. Line styles are unavailable for the author comparison graphs. Stacked bar for author comparisons shows one colored stack of authors. Ordinary bar and line graphs include the source average guide. Integer tick labels reflect commit/line counts. Graph titles and axis units follow the chosen metric and time interval; the original TortoiseGit palette is shared by all graph styles in light and dark appearance. Very high author counts retain the source palette's repeated colors.

With a graph selected, choose File → Save Graph As…. The save sheet has Pictures and All Files filters. The filename selects the encoder: .wmf, .emf, .pdf, .png, .jpg/.jpeg, .bmp or .gif. Changing the filter preserves your typed suffix. Pictures adds .wmf to an extensionless name; All Files adds .jpg. An unknown suffix also gets .jpg appended. The panel confirms the final filename before overwriting or granting access to it.

WMF and EMF both write enhanced metafiles, matching TortoiseGit's .wmf output; they are two filename choices for that format, not a classic-WMF encoder. PDF is also available for vector output. Native display and all exports use the same graph scene and current graph area size. Date pies share one horizontal row and shrink to fit; zero-valued intervals leave no empty slot. All graph styles have a boxed legend on the right. Crowded legends keep the last group and show dots for omitted middle rows; narrow graphs hide the legend. The text summary cannot be exported through this command.

This dialog is still being compared with TortoiseGit. Exact displayed label geometry, outlines/shading, dense history layouts, displayed save-sheet behavior and signed sandbox checks remain pending; see the parity record.

Cancel stops gathering file changes and keeps the previous complete summary. Use Calculate to retry. Closing during calculation first cancels the read, then closes after Git finishes. The summary page hides graph style and author-limit controls; those appear when you select a graph. Save Graph As opens an owned native save sheet; cancelling leaves the graph available for another export.

The author slider's tooltip reports the selected activity cutoff and commit share. When only one author would be omitted, that author keeps a named entry, matching TortoiseGit. The graph style buttons identify the selected style.

Save Graph As captures the graph and its current size and appearance when you open the file panel. Once accepted, the filename, encoder and graph stay fixed while writing. Controls wait for that write to finish. Closing requests cancellation and waits for the worker and owned sheets to finish. A forced close retires the window immediately and releases its ownership after that work drains. Cancellation before atomic publication preserves an existing destination; a file already published remains a successful save. Errors stay attached to the Statistics window.

Calculate captures the originating window's Git backend preferences for the whole read. Cancelling discards partial results and keeps the last complete summary. After it finishes, Calculate can retry. Quit confirmation invalidates pending form and export actions, including callbacks retained from an older presentation.

Author identity is retained through totals, activity ranking, interval graphs, slider selection, legends and graph export. A real author whose name matches the Others caption remains separate from that combined group. Identical-looking labels can therefore have separate entries and colors; the original names remain in tooltips, accessibility descriptions and PDF text. Metafile labels use shaped font outlines to preserve their appearance, so they are not generally searchable or editable as text. Color-font labels may use a small label image; the graph itself remains vector geometry.

Export sizes and drawing complexity are bounded; oversized output fails explicitly. See the Statistics export parity record for the supported formats, adaptations and remaining acceptance work.
