# Bar Chart

A bar chart is a statistical graph used for discrete data. Each bar represents a category (dimension), and the length of the bar is the statistical value (measure) under that category. Bar charts provide a convenient sorting function, making it easy to see the maximum and minimum values.
A typical bar chart is shown below:

## Clustered Bar Chart

A clustered bar chart allows multiple measures to be selected on the Y-axis, forming a comparative relationship. As shown below:

## Grouped Clustered Bar Chart

Compared to a bar chart, a grouped clustered bar chart adds an additional layer of grouping, allowing the graphics of secondary grouping to be clustered together for comparison. As shown below:

## Stacked Bar Chart

Unlike a grouped bar chart that displays categories side by side, a stacked bar chart divides each bar to show the size of each data under the same type.

> \[!CAUTION] Note
> Each group of data must be all "positive" or "negative". If there are both positive and negative numbers, the column will not be displayed in the chart.

## Percentage Stacked Bar Chart

Similar to a stacked bar chart, but each layer of the bar represents the percentage of the data in that category relative to the total data in the group.

## Grouped Stacked Bar Chart

Unlike a grouped bar chart that displays categories side by side, a grouped stacked bar chart divides each bar to show the size of each data under the same type.
A grouped stacked bar chart can visually display the data of each small category contained in a large category, as well as the proportion of each small category, showing the relationship between individual items and the whole.

## Percentage Grouped Stacked Bar Chart

Similar to a grouped stacked bar chart, but each layer of the bar represents the percentage of the data in that category relative to the total data in the group.

## Horizontal Bar Chart

As the name suggests, a horizontal bar chart is formed by swapping the X and Y axes of a bar chart.

## Horizontal Clustered Bar Chart

Multiple measures can be selected, and each measure under each category is displayed horizontally independently.

## Horizontal Stacked Bar Chart

Multiple measures can be selected, and all measures under each category are displayed horizontally stacked.

## Horizontal Percentage Stacked Bar Chart

Multiple measures can be selected, and the proportion of each component under each dimension is displayed horizontally stacked.

## Ring Bar Chart

The difference between a ring bar chart and a bar chart is that the display style is changed to a ring mode. As shown below:
