Description

The XY Plot displays the relationship between two signals. It can be used in PLECS circuits as well as in Simulink models. For detailed information on how to work with the XY Plot see section Using the XY Plot.

Parameters

Title
The name which is displayed above the plot.
Limit samples
If this option is selected, the XY Plot will only save the last n   sample values during a simulation. It can be used in long simulations to limit the amount of memory that is used by PLECS. If the option is unchecked all sample values are stored in memory.
Time range
This option may be used for periodic systems to limit the displayed data to a given number of periods.

The time range value determines the time range that is displayed in the plot. If set to auto, the data over the whole simulation time range is used. If a limit is given and the simulation time reaches an integer multiple of this limit the plot is cleared except for the data covering the last n   time ranges, where n   is the number entered under Show last. The plot is appended until the simulation time reaches the next integer multiple of the time range.

Axis labels
The axis labels that are displayed on the x- and y-axis.
X- and Y-limits
The initial lower and upper bound of the x- and y-axis. If set to auto, the axes are automatically scaled such that all data is visible. Note that setting any of the limits to auto is computationally expensive and may have a considerable impact on the simulation speed.
