Histogram by SmartVisuals

The histogram Power BI took away, rebuilt properly. Named bin rules that reproduce numpy exactly, your own bins when you need them, reference lines, curves, and process capability for quality teams.

Free, and never blocked

• Bins you can name: Freedman-Diaconis (default), Sturges, Scott, Rice, square root, Doane, auto, a fixed number or a fixed width, with round bin edges.
• Bins you choose: type your own edges (0, 10, 12, 15, 20) or set where a bin starts; values outside your edges are counted in the footnote.
• Reference lines: mean, median and up to four percentiles (P90, P95), for all data or per group, by the quartile definition you pick.
• Bars as count, percent of group or density; a cumulative % line, a density curve and a fitted normal curve.
• Benchmark: a line that colours the bars below and at or above it and states the share below.
• Groups: overlaid, stacked or one row per group on shared bins (picked automatically until you choose).
• Dynamic in the Service (no Desktop-only bins), large-data input (Value as column + Count), a smart caption and a methods footnote.

Readers without a licence always see the free chart: no watermark, no broken report.

Power BI features (free)

• Tooltips: bin range, count, share and cumulative share on every bar; report page tooltips supported.
• Highlight and cross-filter: click a group's bar to filter the report, Ctrl adds to the selection, cross-highlighting from other visuals fills the highlighted share of each bar, bookmarks keep the selection, right-click context menu.
• Drilldown on a Group hierarchy (Plant > Line), drill up or expand all; conditional formatting (fx) of the bar colour from a rule on the Value.
• Data labels with bar values; a legend for groups that also names the curves (show, top or bottom position, font size, colour).
• Axes: axis titles, fixed minimum and maximum, decimals, font size and colour, grid lines; a typed target / reference line; horizontal or vertical bars.
• Responsive: on small tiles the caption, footnote and legend step aside so the bars keep their room.
• Format on the canvas (on-object formatting).
• Four themes, four fonts, transparent background, a colour per group; localized in 20 languages (format pane, captions, tooltips, announcements).

Accessibility: one keyboard tab stop. Arrow keys, Home / End and Page Up / Down move between bars with a visible focus outline; Enter or Space filters the report to the focused group, Ctrl adds, Escape clears. A screen-reader live region announces each bar's range and count, and the chart is labelled with its smart caption. The Accessibility card sets the focus outline colour and width and a minimum text size. The normal curve is dashed and statistic lines differ by dash pattern, never by colour alone; high-contrast mode uses the system colours. Nothing animates.

Premium: capability (per-user licence)

• Spec limits your way: typed, or from LSL, USL and Target measures so every product or line is judged against its own specification and follows the slicers.
• Every index: Cp, Cpk, Cpl, Cpu, Cpm, Pp and Ppk (AIAG, Cpm against the target), share and ppm expected outside spec, +/- 3 sigma control limits. An index that cannot be computed is not shown, never guessed.
• Value zones: two or three shaded zones, each with its share of rows (yield per zone).
• Significance between groups, weights, advanced density kernels, small multiples, a second reference line, seven more quartile types, 3+ Split By levels, sorting groups by a statistic.

Premium previews free in Desktop and edit mode. Statistics run offline, golden-tested against numpy and scipy; no external calls.

Single view or the multi-view?

This is the single-view edition ($1.99 per user per month). SmartVisuals Distribution ($4.49) adds box plot, violin, raincloud, ridgeline and beeswarm views over the same fields, with the same premium layer. Licences do not carry across offers. For histograms alone this one is cheaper; with three or more chart types the multi-view is.

New in 1.1.0.0: a benchmark that colours the bars below and above it, drilldown on Group, conditional formatting (fx) of the bar colour; premium value zones with their share of rows and a second reference line; defaults draw exactly what 1.0.1.0 drew. Sorting by a statistic, extra quartile types and 3+ Split By levels are now premium; reports created before 1.1.0.0 keep these features.
