Bar charts, a type of comparative chart, are a type of graph that compares data sizes through the length of equally wide bars. Each bar represents a data category, and the height or length of the bar represents the specific value of that category.

Axes: The horizontal axis (X-axis) and vertical axis (Y-axis) are used to display category labels and numerical scales.
Rectangular Bars: The length or height of the rectangular bars represents the specific value size.
Legend and Data Labels: The legend is used for multi-series comparison, and data labels directly display values.
Bar charts are divided into vertical bar charts (column charts) and horizontal bar charts based on direction.
Vertical bar charts are the most traditional form, with the horizontal axis representing categories and the vertical axis representing values. They are suitable for comparing single values across different categories, such as sales in different regions or sales of different products.
Horizontal bar charts extend bars horizontally, with the horizontal axis representing values and the vertical axis representing categories. They are suitable for situations with long category names or many categories, to avoid overlapping category labels.
Bar charts are divided into basic bar charts, grouped bar charts, stacked bar charts, segmented bar charts, and bidirectional bar charts based on data presentation.
Displays data for multiple categories in groups, with each group containing multiple bars, each representing a value under a subcategory or condition.
Grouped bar charts are suitable for comparing differences under different conditions within the same category, such as data from different years, regions, or genders.
Stacks data from multiple categories together to form a single bar, with each part representing a subcategory, used to show the proportion of each part within the whole.
Stacked bar charts are suitable for displaying the composition of the overall total and the contribution of each subcategory, such as the total sales of different products and the contribution of each subcategory.
In a bar chart, there are two sets of bars, one extending in one direction and the other extending in the opposite direction, forming a contrast in quantity or proportion.
Bidirectional bar charts are suitable for showing increases and decreases or comparisons in data, such as a company's annual financial performance.
Drag the 'Text' shape from the 'Basic Shapes' section on the right to above the bar chart, and double-click to set the title.
Double-click the bar chart, and add text or numbers in the dashed box after the existing categories or series in the right menu bar.
Double-click the bar chart, select the series, category name, or specific data in the right menu bar, click the 'Delete' button, and choose to delete the entire row or column.
Double-click the bar chart, and the legend can be hidden in the right menu bar.
Bar charts and column charts are essentially different presentations of the same type of chart. The core difference is in the orientation layout: column charts have vertical bars, suitable for displaying time series data; bar charts have horizontal bars, suitable for displaying longer category labels.
Bar charts display discrete data (such as product categories, country names), with gaps between bars indicating independent categories. The horizontal axis is for categorical variables, and the vertical axis is for values, used to compare values across different categories. Histograms display continuous data (such as height, test scores), with no gaps between bars indicating continuous intervals. The horizontal axis represents numerical intervals, and the vertical axis represents frequency, used to show the distribution of data.
Bar charts emphasize comparison between categories, suitable for displaying static or categorical data. Line charts focus on showing trends of data changes over time, suitable for continuous data or situations requiring observation of time series.
