The chart types are Bar Chart, Column Chart, Line Chart and Pie Chart.

1, Chart Type - Bar Chart

Usage Scenario: It is applicable to two-dimensional datasets (where each data point includes two values x and y), but there is only one dimension to compare. Advantage: Bar charts utilize the height of the columns to reflect the differences in the data. The naked eye is sensitive to height differences and recognizes them very well. Disadvantage: Bar charts are limited in that they are only suitable for small to medium sized data sets.

2. Chart Type - Line Chart

Usage Scenario: Line Chart is suitable for two-dimensional large datasets, especially those occasions where the trend is more important than a single data point. It is also suitable for comparison of multiple 2D data sets. Advantage: it is easy to reflect the trend of data changes.

3, chart type - pie chart

Usage scenarios: applicable to simple percentage charts, can be used in the case of the data does not require fine. Advantage: can clearly express the same whole, the proportion of different components of the relationship. Disadvantage: the naked eye is not sensitive to the size of the area. Pie chart is a type of area chart, but because of its obvious disadvantages, so when using pie charts and other types of area charts, pay attention to the percentage of the situation with a numerical label.

4, chart type - funnel chart

Usage Scenario: funnel chart for business process is more standardized, long cycle, more links in the process of analyzing the funnel through the funnel of the links in the comparison of business data, to be able to intuitively find and illustrate where the problem lies. Advantage: Can visually identify and explain the problem.

In website analysis, it is usually used for conversion rate comparison, which can not only show the final conversion rate of users from entering the website to realizing the purchase, but also show the conversion rate of each step. Disadvantage: A single funnel chart cannot evaluate the conversion rate of each step in a key process of a website.

5, chart type - radar chart

Radar chart is a spider web-like mesh chart, you can compare two groups of items of multiple variables of the project, it can reflect the data relative to the center point and other data points of change, can clearly reflect the overall situation of things. Usage Scenario: Radar charts are suitable for multi-dimensional data (more than four dimensions), and each dimension must be sortable.

However, it has a limitation that there are up to 6 data points, otherwise it is not recognizable, so the applicable occasions are limited. Disadvantage: It is important to note when users are not familiar with radar charts and have difficulty interpreting them. Try to add a description when using it to reduce the burden of interpretation.
