Line chart¶

Usage¶

Line charts can help users to track changes in data over time, compare performance of different groups and analyze trends and patterns to make timely decisions.

Basic line chart¶

Line charts connect a series of data points using a line. It displays quantitative data series over continuous intervals.

Multiple line chart¶

Use it to visualize trends and relationships in multiple data sets. It compares different data groups on the same scale to find out how each of them is performing compared to the others.

Step-line chart¶

Use it to visualize trends for a particular event that is not continuous in nature. This chart compares the magnitude of change in value and helps to discern the intermittent pattern of the trend.

Best practices¶

• Use appropriate time periods to ensure accurate insights.
• Choose a baseline that suits the data; choosing a zero baseline may not always represent the data change effectively.
• When comparing data sets, line charts are only useful if the axes follow the same scales.
• Don't plot too many lines. Limit the number to five.

Design¶

1. Chart title, 2. Y axis, 3. X axis, 4. Line graph, 5. Legend, 6. Grid-lines

Code¶

Usage¶

import { SiChartCartesianComponent } from '@siemens/charts-ng';

@Component({
  imports: [SiChartCartesianComponent, ...]
})
