In our work, if we need to calculate the total cost or the proportion of each part of the amount, we can use a pie chart to directly display each component and its proportion.
However, if the pie chart has many and dense partitions because of the large number of components, the chart becomes difficult to observe.
Can it be distributed at equal angles (items with small proportions will not be ignored) and reflect the size of each item (items with large proportions are highlighted)? Can also compare the differences of different types (multi-angle analysis)?
There is a chart that can meet the above requirements, it is the Nightingale rose chart.
Nightingale rose diagram The Nightingale rose diagram was invented by Florence Nightingale, also known as the polar diagram, is a circular histogram. Out of worries that the results of data statistics will not be taken seriously, she created this colorful chart format to make the data more impressive.
As shown in the figure below, the sales of three types of products (electronics, furniture, office) in a year and twelve months are summarized and analyzed:
That is, you can see the proportion of each type of product in the 12 months of a year's sales, and the large sales will be highlighted;
You can also see the difference in monthly sales of the three products;
It can also reflect the overall situation of the whole year, that is, the area of red is larger than the area of blue ÿ
