There are often multiple ways of visualizing the same data. However, in the process of visualizing data, we are often constrained by "inertial thinking". The pie chart is often used in statistics modules. It is a circular chart with a special shape such as a pie. But nowadays, the pie chart is not just a three-dimensional pie-shaped chart as we understand it, it has become the general term for a series of charts that show proportions. The pie chart system. So it can be subdivided into pie charts, ring charts, etc. Only the data arranged in one column or row of the worksheet can be drawn into a pie chart. The pie chart displays the ratio of the size of each item in a data series to the sum of each item.
Pie chart features:
(1) Use the area of a fan or three-dimensional pie to represent the percentage of the part in the whole;
(2) It is easy to display the size of each group of data relative to the total.
If you want a clearer understanding of the relationship between the number of parts and the total, you can use a pie chart.
How to make a pie chart look good?
A pie chart can display the proportions of various sizes and totals in a data row and column, which is equivalent to a pie chart that can be divided into multiple separated blocks and can distinguish the different sizes of each block. The pie chart is more suitable for each data with a data column, which is usually used in the statistics module. Generally, the pie chart can be made by Excel. How to make the pie chart look good? Pie chart production is relatively simple, as long as different size blocks are used to represent different data. But if you want to make a good-looking pie chart, Excel cannot do it, so you need to use professional pie chart software.
Professional pie chart making software
The pie chart produced by Excel pie chart making software is relatively simple and looks a bit rigid. How to make the pie chart look good? You can use Smartbi software to make. Because Smartbi is a professional drawing software, the pie chart produced can show different colors according to different blocks. A good-looking pie chart can not only visually see the amount of data in each block, but also the distribution of data directly from the size and color of the block, so few people use Smartbi to make good-looking pie charts.
For example, Smartbi, a popular software from Sematic on the market, has cutting-edge functions. It can be used for BI reports and large screens, including data integration, modeling, analysis, and visualization. It is very suitable for enterprise use. The difficulty is not too great, and the effect is good.
The following figure is a commonly used pie chart: it shows the proportion of sales in each quarter of the year to the whole.
Let's use Smartbi to make the above pie chart to view the proportion of sales of each product category in the company.
The data sources of the above business scenarios are as follows:
Steps of making a pie chart by Smartbi:
Step 1: Double-click the "Quarter" and "Sales" fields, and the system will automatically assign dimensions to the "Color" marked item and the measurement to the "Angle" marked item. The graph made at this time does not show the percentage. Drag "Sales" to the "Label" item, hover the mouse on the "Sales (Total)" field label, a triangle button will be displayed, click the button:
In the pop-up menu, select Quick Table Calculation> Total Percentage to display the percentage, as shown below:
You can clearly see the percentage of each product to the overall situation.
Step 2: The graphics also supports rich sub-pictures for switching, which enriches the display form, as follows:
Pie chart: The circle is divided into several pieces, representing different categories, and the size of the piece indicates the size of the data.
Ring chart: A ring chart is a graphic formed by stacking two pie charts of different sizes and cutting out the middle part. The color block area is relatively small, with more white space, and more space for information labeling and graphic typesetting, making it more flexible and lightweight when used.
Nightingale rose chart (area model): The central angle of the circle occupied by each category is constant, and the size of the data series is represented by the radius of the sector. A rough proportion can be obtained, giving a strong sense of difference.
Nightingale's rose chart (radius mode): The central angle changes with the radius. The size of the data series is expressed by the size of the central angle and the radius. The approximate proportion can be obtained, giving a strong sense of difference.
