Quick BI:Line Chart

Overview

Scenarios

• Trend widgets are used to display continuous data that changes over a specified period of time. You can use trend widgets when you want to show the overall trend of data at equal intervals.

• A line chart helps you learn the overall trend of data over a period of time. For example, data increases, decreases, periodically changes, or exponentially increases over a specific period of time. You can also compare data of multiple line charts.

Benefits

• Powerful computing capabilities: A vertical bar chart allows you to configure parameters, such as Comparison, Cumulative Calculation, Gridlines, and Trendline.

• Abundant data visualization: The chart type of a line chart can be a curve and a line chart. A line chart allows you to configure parameters, such as Label, Show Legend, and Show Scroll Bar.

• Data comparison and labeling: A line chart allows you to compare data in the same period and label data by using numbers.
