1) Applicable scenario: The applicable scenario is a two-dimensional data set (each data point contains two values of X and Y), but only one dimension needs to be compared to show the data changes in a period of time or to show the comparison between projects.

2) Advantages: The histogram reflects the difference of data with the height of the column, and the naked eye is very sensitive to the height difference.

3) Disadvantages: The limitation of histogram is that it is only applicable to small and medium-sized data sets.

4) Expansion chart: Stacked bar charts and percentage stacked bar charts can not only visually see the values of each series, but also reflect the sum of the series, especially when it is necessary to look at the composition of a unit and the specific gravity of each series.

2. Line chart

1) Applicable scenario: Line charts are suitable for large two-dimensional data sets and comparison of multiple two-dimensional data sets.

2) Advantages: It is easy to reflect the trend of data changes.

3. Pie chart (ring chart)

1) Applicable scenario: display the ratio of each size to the sum of each item. Simple scale diagram is applicable, and it is applicable when fine data is not needed.

2) Advantages: The data ratio is clearly displayed, which is especially suitable for scenes such as channel sources.

3) Disadvantages: the naked eye is not sensitive to the size of the area.
