    Dark wind rose with sixteen compass points from N clockwise, petals stacked by wind speed band and the share of each direction

    What it does

    SmartVisuals Rose is a polar area chart, Nightingale rose, coxcomb and aster in one visual, sized by area so that a petal twice the value has twice the area. Months, weekdays, hours of the day and compass points are recognised and kept in their cycle: a wind rose starts at north, an hour rose puts midnight at the top, and no month is ever folded into Other.

    Stacked petals, a radial axis, half and three-quarter arcs, a centre total and images in petals are free. Premium compares per petal: last period's outline, past seasons as fading outlines, targets, seasonality findings and small multiples. SmartVisuals Part-to-Whole carries the same rose next to pie and donut, radial bar, waffle, pictogram, funnel and Marimekko.

    Rose in Power BI, explained

    6 short chapters: what the visual does and why

    What is a rose chart, and why should petals be sized by area?

    A rose chart (polar area chart, Nightingale rose, coxcomb) gives every category an equal slice of the circle and lets the value decide how far the petal reaches. It suits cycles: months of the year, hours of a shift, days of the week, compass directions. The trap is the radius. If a petal's length is proportional to its value, its area grows with the square of the value, and a month with twice the orders looks four times as big.

    SmartVisuals Rose sizes petals by area by default (Rose > Petal Size > By area (honest)): a petal twice the value has twice the area, and the footnote says "Petal area is proportional to the value." By radius is available on request, with a footnote that the areas exaggerate large values, and Aster takes the petal angle from a second measure in Angle (aster), so two measures read in one rose.

    How do I keep months, weekdays, hours and compass points in order?

    Rose > Order > Auto recognises months and quarters, weekdays (Monday first, in English and the visual's other languages), hours of the day ("00:00", "6 AM", "14h" and similar) and compass points (4, 8 or 16 points, abbreviations or full English names), and keeps them in their cycle whatever the sort order of the column. Calendar, Weekdays, Hours of the day, Compass points or As the Sorting card fix the order by hand.

    A cycle keeps every period: months are never folded into Other. Hours and compass points also keep their place on the circle, so a wind rose puts N at the top and an hour rose puts midnight there, even when some hours or directions have no data and their gap is left open.

    How do I build a wind rose or stacked petals?

    Put the direction (N, NNE, NE and so on) in Category, the speed band in Segment and the hours or counts in Values. Rose > Stack Petals by Segment, on by default, stacks the bands inside each petal, Nightingale's own layout, and every band is sized by area, not only the outer edge. The legend lists the bands, and the caption names the largest direction and the share of the top three.

    Rose > Arc draws a full circle, a semicircle, three quarters (270°) or a custom start and sweep, so the twelve hours of a day shift can sit on a half circle with the shift total in the centre (Inner Radius (%) opens the hole). Radial Axis adds grid circles at round values with axis labels; Maximum (0 = auto) fixes the scale so two roses on a page compare.

    How do I compare this season with past seasons? (premium)

    Put last year's measure in Compare and every petal gets last year's outline, with the change in its label and tooltip. Put a field such as Year in Seasons instead, and the latest season is drawn as petals and up to six past seasons (Rose > Past Seasons as Outlines) as outlines that fade with age. The findings then say how far the peak sits above its average of the past seasons, and how the peak-to-low swing compares: "Aug, the peak, is 43 % above its average of the past 3 seasons (3.7K)."

    Findings also give the seasonal index of every petal (period value ÷ mean of the periods, 100 % = average) and whether the peak moved against last period. Targets per petal draw an arc across each petal at its target, in met, close or missed colour, and Small multiples draws one rose per plant on a shared radial scale. Each number is golden-tested against numpy.

    What does the rose leave out, and why?

    Negative and blank values cannot be drawn as an area, so they are left out and counted in the footnote. A rose with many petals is hard to read; with more than 24 petals the edit-mode hint suggests grouping small ones into Other or filtering the category. Labels that do not fit are dropped whole instead of overlapping, and axis values are drawn only beyond the edge of the petals so they never smudge over them.

    Rose or the Part-to-Whole multi-view?

    SmartVisuals Rose is the single-view edition at $1.99 per user per month or $19 per user per year, with the first month free. SmartVisuals Part-to-Whole, at $4.49 per user per month or $45 per user per year, holds this view plus pie and donut, radial bar, waffle, pictogram, funnel and Marimekko over the same fields, with the same free tier and premium layer. Licences do not carry across offers: for one or two chart types the single views cost less, for three or more the multi-view does.

    Use cases

    Where Rose earns its place

    A wind rose for the Chicago plant's weather station

    The site team counts hours per Direction (N, NNE, NE ... NNW) and Speed band (0-2 m/s up to 8+ m/s). Direction goes to Category, Speed band to Segment and Hours to Values. The rose puts N at the top and the sixteen points in compass order, stacks the speed bands inside each petal, sizes every band by area and names the prevailing direction in the caption: "WSW is the largest share at 14 %."

    Alarms per hour of the day shift

    Maintenance filters the alarm log to the day shift and puts Hour (06:00 to 17:00) in Category and Alarms in Values, with Rose > Arc set to Semicircle and an inner radius for the shift total. The hours stay in clock order and the caption names the busiest and the quietest hour: "06:00 is the peak at 58; 13:00 the low at 23."

    This year's orders against the last three

    Sales puts Month in Category, Orders in Values and Year in Seasons (premium). The latest year is drawn as petals and the three before it as outlines that fade with age; the findings say that August is the new peak, 43 % above its average of the past three seasons, and how the peak-to-low swing compares.

    Revenue and volume per plant as an aster

    Plant in Category, Revenue in Values and Units in Angle (aster), with Rose > Petal Size set to Aster. Petal length comes from revenue and petal angle from units sold, so a plant that sells many cheap units shows as a wide, short petal.

    Category and one measure in Values. Optional: Segment (stacked petals), Compare (last period or plan), Target, Angle (aster), Icon (images in petals), Annotation, Seasons (past seasons as outlines), Small multiples, Tooltips, Centre value and Show condition.

    They are the same chart: equal angles, and the value decides the size of each petal. Florence Nightingale's coxcomb stacked several causes inside each month. An aster varies the angle as well, from a second measure. A radial bar chart is different: each bar is an arc whose length, not area, carries the value.

    By area, a petal's radius grows with the square root of the value, so a petal with four times the value reaches only twice as far. That is the honest reading. Rose > Petal Size > By radius makes the length proportional instead, and the footnote then says that the areas exaggerate large values.

    Rose > Order > Auto puts months, weekdays, hours and compass points in their cycle; if the names are unusual, choose Calendar, Weekdays, Hours of the day or Compass points by hand. As the Sorting card uses the Sorting and Other card instead.

    No. The visual declares no network privileges, makes no external calls and sends no telemetry. Areas, seasonal averages and indexes are computed inside the visual in your report. The licence is checked through Power BI's own licensing service.

    Rose is the single-view edition at $1.99. SmartVisuals Part-to-Whole ($4.49) adds pie and donut, radial bar, waffle, pictogram, funnel and Marimekko views over the same fields, with the same engine. Microsoft licenses every offer separately, so a licence for one never unlocks the other.

    Yes. The chart is one tab stop: the arrow keys walk the petals, Home and End jump to the first and last, Enter or Space selects (Ctrl adds), and Escape clears. A polite live region reads each petal with its value and share, and the Table button opens an accessible data table.

    Yes, for free: an Icon measure returning a built-in name (factory, bolt, truck, drop and others), an SVG path or a data:image URI draws an image in every petal that has room for it. Web addresses are ignored, so no image is fetched from outside the report.

    20: English, Czech, Danish, Dutch, French, German, Hungarian, Italian, Japanese, Korean, Norwegian, Polish, Portuguese (Brazil), Portuguese (Portugal), Slovak, Spanish, Swedish, Turkish and Chinese (Simplified and Traditional), for the format pane and every string the visual writes. Numbers follow the report's locale.

    Troubleshooting

    When it does not look right

    Found a bug or missing something? Post it on the requests board; the developer answers within two business days.

    My months or weekdays are in alphabetical order.
    Rose > Order > Auto recognises months, quarters, weekdays, hours and compass points and keeps them in their cycle. If your names are unusual, set Order to Calendar, Weekdays, Hours of the day or Compass points by hand; As the Sorting card uses the Sorting and Other card instead.
    The petals look smaller than I expected.
    Petals are sized by area, so a petal with four times the value reaches only twice as far from the centre. That is the honest encoding. Rose > Petal Size > By radius makes the length proportional, and the footnote then says that the areas exaggerate large values.
    The aster petals all have the same angle.
    Aster takes the angle from a second measure: add one to Angle (aster). Until then the petals use equal angles and the edit-mode hint says so.
    Some directions or hours are empty gaps.
    Hours and compass points keep their fixed place on the circle, so a direction or hour without data leaves its slot open instead of shifting the others. Gaps are intended; they show where nothing happened.
    Past seasons do not appear.
    Seasons are drawn with a field in Seasons (such as Year) and a licence; the latest season becomes the petals and up to six past seasons the outlines (Rose > Past Seasons as Outlines). A Play axis bound at the same time takes over, and Seasons is then not drawn.
    Premium features show in Desktop but not for some readers.
    Premium previews in full in Power BI Desktop and edit mode. In reading view a reader without a licence sees the free rose, with the premium layers set aside in memory, and Power BI shows its own licence banner once; nothing is blocked or watermarked.

    Accessibility

    Keyboard, screen readers and high contrast
    Tab
    Moves into the chart, which is one tab stop; the first petal gets a focus outline. The Table button, and the sort button when it is shown, are separate tab stops.
    Arrow keys
    Move to the next or previous petal.

    Esc
    Clears the selection.

    • Screen readers

      The chart is labelled with its smart caption, a sentence that says what it shows. A polite live region announces the focused petal as you move, with its name, value and share of the whole.

    • Data table

      The Table button in the corner of the visual (Data Table > Table Button in the Visual, on by default) switches between the chart and an accessible table of every petal with its value and share; Data Table > Open as Table starts in the table.

    • Not colour alone

      Format pane > Accessibility > Patterns (Tell Items Apart Without Colour) gives every petal or stacked band a fill pattern. Last period's outline is drawn as a dashed line, so it differs from the petals by line as well as by colour, and change labels carry the sign of the change.

    • High contrast

      In Windows high contrast mode the visual uses the contrast theme's foreground, background and selection colours, ignores the transparent background, and always turns on the fill patterns.

    • Reduced motion

      Accessibility > Reduce Motion, or the operating system's reduced-motion setting, turns off transitions.

    • Focus outline and text size

      Accessibility > Focus Outline Colour and Focus Outline Width (2.5 px by default) set the dashed outline around the focused petal, and Minimum Text Size keeps every label at or above the size you set. Labels that do not fit are dropped whole, never cut or overlapped.

    • Context menu

      Right-clicking a petal or the empty canvas opens the Power BI context menu.

    • Languages

      The format pane, captions, footnotes, findings, tooltips, the data table and the screen-reader labels are available in 20 languages: Chinese (simplified and traditional), Czech, Danish, Dutch, English, French, German, Hungarian, Italian, Japanese, Korean, Norwegian, Polish, Portuguese (Brazil and Portugal), Slovak, Spanish, Swedish and Turkish.
