SystemModelPlot

SystemModelPlot[sim]

shows default plots from the SystemModelSimulationData object sim.

SystemModelPlot[sim,"name"]

shows model plot "name".

SystemModelPlot[sim,{"v₁","v₂",…}]

generates a plot of the variables v_i in sim.

SystemModelPlot[{sim₁,sim₂,…},…]

plots variables from several simulations.

SystemModelPlot[model,…]

plots from a new simulation of "model".

Details and Options

SystemModelPlot[…,{t_min,t_max}] plots from t_min to t_max.
SystemModelPlot[{model,args},…] generates simulation data using SystemModelSimulate[model,args].
The model can be a SystemModel object, a full model name string or a shortened model name accepted by SystemModel.
SystemModelPlot[sim,{{"v₁","p₁",d_i},…},…] plots variables v_i and sensitivity bounds when parameter p_i varies 100d_i%. »
A list of model plots for SystemModelSimulationData sim is available with sim["PlotNames"].
SystemModelPlot has the same options as ListLinePlot, with the following additions and changes:

AxesLabel	Automatic	indicate units on axis
Mesh	None	mesh points to draw on each line
PlotLegends	Automatic	use variable names v_i
TargetUnits	Automatic	plot in display units from model

Events in a simulation are indicated in a plot with Mesh->"Events". »
Possible settings for TargetUnits include:

	"DisplayUnit"	display units converted to common units
	"IndividualDisplayUnit"	display units without conversion
	"Unit"	base units converted to common units
	"IndividualUnit"	base units without conversion
	unit	explicit unit

"Unit" and "DisplayUnit" attempt to convert compatible quantities to a common unit.
"DisplayUnit" and "IndividualDisplayUnit" convert to a unit specified in the model for plot purposes.

Presentation (10)

Multiple variables are automatically colored to be distinct:

Use PlotStyle to change the plot colors:

Filling can be used to specify fill regions and styles:

Fill between the two curves:

A legend is automatically shown for plots with multiple variables:

Turn off PlotLegends:

Style legends:

Events can be illustrated with Mesh points:

For multiple simulations:

Use any expressions in plot legends:

Do multiple simulations:

The Tooltip and plot legends show which simulation the curve belongs to:

SystemModelPlot sets the option AxesLabel:

Override by setting AxesLabel:

Wrappers like Style can be used for styling variables:

Setting a Tooltip removes all automatic tooltips:

Plots are shown in display units defined in the model:

Use TargetUnits to choose a different unit:

Options (6)

PlotLegends (1)

Use variable names as PlotLegends:

Use variable descriptions:

TargetUnits (5)

Plot different units in the same plot:

Variables of the same physical dimension are converted to the same unit:

Use "IndividualDisplayUnit" to use the given display unit for each variable:

Use an explicitly given unit:

Plot in a common base unit from the model:

Use the individual base units without converting to a common unit:

Turn off unit handling completely for maximum performance:

Applications (3)

Do a parameter sweep:

Compare the different simulations to a first-order system:

Find out which of three parameters a model is most sensitive to:

A 5% sensitivity bound on the output shows that "sine.freqHz" has the highest impact:

Show a custom explanatory legend:
