An arc chart is a data visualization chart that uses arcs to represent relationships and distributions among data points, helping users better understand complex relation networks.
Prerequisites
You have created a dashboard. For more information, see Create a Dashboard.
Chart Overview
Scenarios
Arc charts are suitable for displaying and analyzing complex relation networks. They reveal patterns, change trends, and associations to help solve problems such as sales data analysis, financial market analysis, traffic network analysis, and Network Security analysis. They enable users to observe change trends between data more intuitively.
Benefits
Arc charts provide benefits such as visualizing complex relationships, highlighting key nodes, and discovering patterns and change trends. They deliver intuitive and effective data display.

Limits
An arc chart consists of Source/Dimension, Target/Dimension, and Connection Value/Measure.
Source/Dimension and Target/Dimension are determined by the data’s source dimension. Select only one dimension, such as region or product type.
The Limit Value/Measure is determined by a single data measure, such as Total Sales by Region.
Chart Field Configuration
On the tab, select the required dimension and measure fields.
In the Source/Dimension column, select data by double-clicking or dragging.
In the Target/Dimension column, select the Target dimension data.
In the Connection Value/Measure column, select the measure data reflected in the connection value.
Click Update. The system automatically updates the chart.
To view data for a specific region, set a filter to retrieve the required data.
Auto-refresh
After enabling this option, the system automatically refreshes the chart data. For example, select this option and set the duration to 5, with the unit set to minutes. The system then refreshes the chart data every 5 minutes.
