Create a Nightingale rose chart showing monthly sales revenue for the first half of the year

Here's a Nightingale rose chart (also called a coxcomb chart) showing monthly revenue for H1, where each petal's radius represents the sales volume.

How to make a rose chart

No template to fill in and no drawing. You talk; the canvas keeps up.

Monthly revenue for January through June

Supply category values

Paste one value per category and state the unit, such as visits, hours, or millimeters.

Choose the circular order

Keep months, weekdays, or directions in their natural sequence so neighboring sectors make sense.

Check the encoding

Review the numbers and ask for clear labels explaining how petal size relates to the data.

What is a rose chart?

A rose chart arranges values around a circle as petals or sectors. It can emphasize repeated seasonal patterns, but readers need labels to understand the size encoding and compare close values.

Use a circle when order has meaning

Seasonal demand, weekly activity, and directional observations can benefit from circular placement. For precise comparisons between unrelated categories, bars are usually easier to read.

Keep circular data readable

State the size encoding. Radius-based and area-based designs are not interchangeable.
Preserve natural order. Do not rank months by value if seasonality is the point.
Label units. A petal labeled 40 is ambiguous without its measurement.
Handle gaps honestly. Missing observations must not silently become zero.
Limit decoration. Use color to identify categories, not to imply an extra measurement.

From values to petals

MyMap can arrange your supplied values as a rose chart and revise it through follow-up requests. The fixed example displays January through June revenue using a radius-style rose configuration; it should not be described as an equal-angle, area-proportional chart.

Common questions

Is the example an area-proportional Nightingale chart?

The example uses a radius-style rose configuration. Do not read its petal areas as a strict proportional encoding; consult the value labels.

Do values need to add up to 100?

No. Counts, revenue, and measurements can be shown directly when they share a unit. Explain whether the data are totals, averages, or percentages.

Can a rose chart show negative values?

Negative changes are difficult to interpret as petals. Use a diverging bar or waterfall chart when the sign of a value matters.
