Evaluations & charts

Last modified: 23 Jul 2025

Charts in the evaluation section provide visual representations of SYSTEM LEVEL data. Which charts are available for your specific system depends on the components and configurations of your system, as well as on your service level and/or additional paid VCOM modules.

Overview of the evaluation section

To reach the evaluation section, enter the SYSTEM LEVEL for a system in the systems list and then select the tab Evaluation, or select Evaluation right away when hovering over a specific system in the systems list.

The evaluation section is divided into four main areas:

• A List of charts that is grouped by category.

• The Chart area displays the selected chart in full size. Several functionalities are available here.

• The Chart description tells you what you are looking at.

• The Chart data and further details of the selected chart.

Functionalities of the chart area

In the chart area, you can adjust your chart view, learn about specific data points, and download chart data and images. The functionalities are listed below:

	Name	Detail
1	Excel export	Quickly download the chart values as an Excel file.
2	Time	Select the time you want to display. It depends on your Period settings whether this is, for example a specific day or a year. Choose specific dates or refine user-defined time in the Calender above the chart description.
3	Update	Update the chart view, for example after changing the time or period.
4	Today	Jump to the current time. It depends on your Period settings whether this is, for example a specific day or a year.
5	Period settings	You can change the period of the displayed data. Choose between day, week, month, year, total, or user-defined view. Note Not all time periods are available for all charts. Charts that display power or energy: Usually, in daily and weekly view the single values of the measurement interval are displayed as power (in W). Usually, as of the monthly view the values are aggregated and displayed as energy (in Wh).
6	Download menu	Choose from various formats to download the chart or its data.
7	Zoom in	Drag the mouse over an area to zoom in on a specific section of the chart.
8	Data points	Hover over an area to display individual data points and their values.
9	Highlight item	Hover over a measured value in the legend to highlight the corresponding data point in the chart. Select and deselect measured values to change their visibility in the chart.
