time series Charts are widgets designed to represent data values with respect to time

¶ Data
In the Chart Widget, you can select multiple devices and parameters as needed.

This flexibility allows for a comprehensive comparison of data from different devices within a single chart

Editing Chart Features: The panel on the right side is where you can configure the chart features.
- Title and Subtitle: First, input a title for your chart. If needed, you can also provide a subtitle.
