Each wedge is further divided into blocks of colour, which represent the causes of mortality. The area of each wedge, measured from the central point, corresponds to the number of mortalities that month, with a larger wedge indicating a higher rate of mortality. In the ‘Rose Diagram’ – also known as the ‘Coxcomb’ or ‘Wedges’ ( Small, 2010, p 1) – twelve wedges, one for each month of the year, are arranged around a point. Nightingale believed diagrams to be a vital means of communicating statistics to non-specialist audiences, writing, ‘diagrams are of great utility for illustrating certain questions of vital statistics by conveying ideas on the subject through the eye, which cannot be so readily grasped when contained in figures’ ( Nightingale, 1858). As Martineau firmly asserts in the preface, England and her Soldiers is no ‘work of invention’ ( Martineau, 1859, p 5) rather, it is a serious endeavour to campaign for better military health care.

Perhaps most significantly, the pair illustrated their argument with Nightingale’s ‘Rose Diagram’, a statistical graphic which demonstrates that the primary cause of death amongst soldiers was infectious disease, not injury incurred in battle. A literary account of the Crimean War which marries Martineau’s text with Nightingale’s statistical studies, the book was intended to inform the public of gross failings in military health care provision during the conflict. In 1859, the writer Harriet Martineau and the statistician Florence Nightingale published a little-known book called England and her Soldiers. Harriet Martineau, England and her Soldiers, 1859 The pair illustrated their book with Nightingale’s ‘Rose Diagram’, a statistical graphic which simply illustrated the rate of mortality.Ĭrimea, Crimean War, Disease, England and her Soldiers, Florence Nightingale, Florence Nightingale Museum, Harriet Martineau, Healthcare, Literature, Martineau, Mathematics, Mathematics Gallery, Medicine, Military, Nightingale, Nineteenth Century, Nursing, Sanitation, Science Museum, Statistics, Victorian View tags for the article Introduction As such, Nightingale’s data was interwoven with Martineau’s text. Martineau and Nightingale grasped that the lay reader was more receptive to statistical information in a literary format than in dense statistical reports. She worked with the government’s Royal Commission investigating healthcare during the war, but also worked privately with Martineau to publicise her findings. After the war, she launched a campaign to convince the British government to make permanent reforms to military healthcare, compiling a dataset on mortality in the Crimea. Whilst working as a nurse in the Crimea, she witnessed thousands of soldiers die of infectious diseases that might have been prevented with proper sanitation. Nightingale was passionate about statistics and healthcare. The book is a literary account of the Crimean War, written by Martineau and based on Nightingale’s statistical studies of mortality during the conflict.

How to make a Nightingale’s Rose chart with Vizzlo?įollow these easy steps to create your Nightingale’s Rose chart online: This meteorological chart is called “wind rose” and uses the compass rose as a reference to display the principal winds (cardinal and ordinal directions). Check the examples to get inspired!Ĭuriosity: Meteorologists use this graph as a tool to visualize the distribution of wind speed and direction on a location. Her rose chart is especially appropriate (but not only) to visualize seasonal/periodic data. The invention of this diagram is attributed to Florence Nightingale-a British nurse and social reformer, who in 1858 developed this chart type to represent the causes of death of British soldiers during the Crimean War graphically. Differences between categories and groups are made visually evident through the filled areas of these segments. In this graph, the proportional areas are plotted in a polar coordinate system, divided into equal segments (with the same angle). Also referred to as “polar area chart” or “coxcomb chart,” the Nightingale’s Rose chart is a circular graph that combines elements of a radar chart and a column graph.
