Creating a Common Chart

Charts can help you present data analysis results in a clear and intuitive way. This section introduces different types of charts in large screens and their use cases, to help you in quickly selecting the appropriate chart for data presentation and display.

Prerequisites

A project has been created by referring to Creating a Project.
A data source has been connected by referring to Creating a Data Source.
A dataset has been created by referring to Creating a Dataset.

A large screen has been created by referring to Creating a Large Screen.

Procedure

Log in to the DataArts Insight console.
Click in the upper left corner of the management console to select a region. Then, select an enterprise project in the upper right corner.
On the top menu of the console, click Project. On the displayed My Projects page, click the name of the desired project.
In the navigation pane on the left, choose Data Analytics > Large Screen. On the displayed page, click Create Screen in the upper right corner.
The Common charts page shows common chart templates.
Drag or click a chart template to the canvas area.
In the data configuration area on the right, select a dataset.
Select the required chart type and configure fields and styles.
Once the large screen fields and style are configured, click Update in the lower part. Then, click Save and Publish or Save in the upper right corner of the page.

Chart Types and Description

Each chart has its use cases and data elements (fields that form the chart). The following describes the use cases, data elements, and examples of various charts.

**Table 1** Use cases
Type	Chart	Description	Data Element
Line Chart	Line Chart	Line charts are used to display the trend of data over equal time intervals.	Class Axis/Dimension Axis Value/Metric Color Legend
	Combination Chart	Combination charts support dual-axis display of data with different magnitudes, and support data display scenarios for conventional line and column chart combinations. In a combination chart, the line chart can display continuous data that changes over time (based on commonly used ratios), making it ideal for displaying the trend of data over equal time intervals. In a combination chart, the bar chart can compare the differences between various groups of data.	Class Axis/Dimension Axis Value/Metric Color Legend
	Dual Y-Axis Combination Chart	Data of different magnitudes is displayed on two axes. In a combination chart, the line chart can display continuous data that changes over time (based on commonly used ratios), making it ideal for displaying the trend of data over equal time intervals. In a combination chart, the bar chart can compare the differences between various groups of data.	Class Axis/Dimension Primary Axis Value/Metric Secondary Axis Value/Metric Color Legend
	Step Line Chart	A step graph is a graphical representation of continuous data distribution.	Class Axis/Dimension Axis Value/Metric Color Legend
Pie Chart	Pie Chart	A pie chart shows the proportion of each item's size to the total sum of all items in the data.	Class Axis/Dimension Axis Value/Metric Color Legend
	Rose Chart	A rose chart displays comparisons between different data points and is particularly useful for categorical data.	Class Axis/Dimension Axis Value/Metric Color Legend
	Circular Progress Bar	A circular progress bar provides a visual representation of the progress of a specific indicator.	Progress Value/Target Value/Metric
	Radar Chart	A radar chart can display analyzed data or ratios, allowing you to easily check various data indicators and trends.	Class Axis/Dimension Axis Value/Metric Color Legend
Bar Chart	Bar Chart	Bar charts are useful for comparing differences between data groups and displaying changes in data over a period of time.	Class Axis/Dimension Axis Value/Metric Color Legend
	Horizontal Bar Chart	A horizontal bar chart is similar to a column chart, but displays data horizontally to allow for easy comparison of data sizes and differences between items.	Class Axis/Dimension Axis Value/Metric Color Legend
	Combination Chart	Combination charts support dual-axis display of data with different magnitudes, and support data display scenarios for conventional line and column chart combinations. In a combination chart, the line chart can display continuous data that changes over time (based on commonly used ratios), making it ideal for displaying the trend of data over equal time intervals. In a combination chart, the bar chart can compare the differences between various groups of data.	Class Axis/Dimension Axis Value/Metric Color Legend
	Dual Y-Axis Combination Chart	Data of different magnitudes is displayed on two axes. In a combination chart, the line chart can display continuous data that changes over time (based on commonly used ratios), making it ideal for displaying the trend of data over equal time intervals. In a combination chart, the bar chart can compare the differences between various groups of data.	Class Axis/Dimension Axis Value/Metric Secondary Axis Value/Metric Color Legend
	Gantt Chart	A Gantt chart is used to display the progress of various tasks.	Title/Dimension Name/Dimension Status/Dimension Start Time/Dimension End Time/Dimension
