Expected energy (simulation) – level comparison chart

Last modified: 2026-06-15

Previously, the chart was called: Variance analysis chart.

Chart

View the chart at System level in the Evaluation tab in the Section: System.

Basic info

Description	The chart displays: The actual energy (as bar chart) The expected energy (as area chart and single data point) The exact target value of the expected energy is displayed as single data point. In reference to this data point, the area chart in the background shows three percentage areas of that value in different colors. In reference to these percentage areas, the bars displaying the actual energy are colored depending on the percentage actually measured. 📗 Example If the upper end of a bar reaches the green area in the background it will be colored green as well. This means that the system is performing very well. If the upper end of a bar also exceeds the single data point (triangle), the system's performance is even better than expected in the simulation. If a bar is red the system should be checked.
Prerequisites	Simulation method for the expected power/energy is configured. See also Configure the simulation.

Description

The chart displays:

The actual energy (as bar chart)
The expected energy (as area chart and single data point)

The exact target value of the expected energy is displayed as single data point. In reference to this data point, the area chart in the background shows three percentage areas of that value in different colors.

In reference to these percentage areas, the bars displaying the actual energy are colored depending on the percentage actually measured.

Example

If the upper end of a bar reaches the green area in the background it will be colored green as well. This means that the system is performing very well. If the upper end of a bar also exceeds the single data point (triangle), the system's performance is even better than expected in the simulation. If a bar is red the system should be checked.

Prerequisites

Simulation method for the expected power/energy is configured. See also Configure the simulation.
