1. Bar chart: also known as bar chart, it indicates the situation of independent indicators at different stages, with two or more dimensions, and the legend is located at the upper right. Bar chart can clearly display the figures of each stage, and it is the most commonly used graph in statistical chart data analysis.
2. Dial indicator and chart: also known as fan chart, it describes the size of percentage (composition ratio), and indicates different proportions with colors or various graphs. The percentage bitmap represents the total with the whole circle, and the size of each sector in the circle represents the percentage of each part in the total. The relationship between the number of each part and the total number can be clearly expressed through the fan-shaped statistical chart.
3. Line chart: The fluctuation of lines indicates the development trend of things, which is suitable for continuous data and reflects the development trend of things in time, or the change of one phenomenon with another phenomenon.
4. Semi-logarithmic line graph: a line graph with the vertical axis as logarithmic scale and the horizontal axis as arithmetic scale. On the logarithmic scale, the distance of the same growth rate changes equally, so semi-logarithmic line charts are often used to compare the development speed of things.
5. Histogram: describes the frequency distribution of the measured data.
6. Scatter chart: use two sets of data to form multiple coordinate points, investigate the distribution of coordinate points, judge whether there is some correlation between two variables or summarize the distribution law of coordinate points. It is often used to describe the correlation between two phenomena.
7. Statistical chart: Describe the geographical distribution of a phenomenon.
Extended data:
Since the 20th century, with the rapid development of science and technology, great changes have taken place in society, and statistics has entered a period of rapid development. From socio-economic statistics to multidisciplinary development. Before the 20th century, the fields of statistics were mainly demographic statistics, vital statistics, social statistics and economic statistics.

It is widely used to study all aspects of society and nature, and has developed into a science with many branches. Health statistics is a branch of statistics.
Health statistics mainly include two aspects:
1, health statistics, including medical demography statistics, morbidity statistics and growth and development statistics;
2, health service statistics, including health resources utilization, medical and health service demand, medical and health system reform and other statistical issues.
