plot

Plot logged simulation series values against time

Description

example

fh = plot(series) plots the simulation series values along the y-axis, with time along the x-axis. fh is a structure of handles to the resulting figures. series is a simscape.logging.Series object. series must include a full identifier path to the series, starting with the workspace log variable name.

example

fh = plot(series,Name,Value) lets you customize the plot by using one or more Name,Value pair arguments. For example, specify 'time' followed by a 1x2 vector, [start_time end_time], to plot only the data within this time range.

Examples

collapse all

Plot velocity of port R of a Translational Spring block.

Open the Mass-Spring-Damper with Controller example model:

ssc_mass_spring_damper_control

This example model has data logging enabled for the whole model, with the Workspace variable name parameter set to simlog_ssc_mass_spring_damper_control.

Simulate the model to log the simulation data:

sim('ssc_mass_spring_damper_control');

Plot velocity of port R of the Translational Spring block Spring.

plot(simlog_ssc_mass_spring_damper_control.Spring.R.v.series);

Customize the previous plot using the name-value pair arguments.

This command plots the velocity of port R of the Translational Spring block in mm/s and only within the time range between 2 and 7 seconds.

plot(simlog_ssc_mass_spring_damper_control.Spring.R.v.series,'units','mm/s','time',[2 7]);

Input Arguments

collapse all

Simulation data to plot, specified as a simscape.logging.Series object or a homogeneous cell array of such objects. series must include a full identifier path to the series, starting with the workspace log variable name.

The table describes the resulting plots based on the type of the series argument:

Scalar Series object

Plots the simulation series values along the y-axis, with time along the x-axis.

Nonscalar Series object

Plots each dimension of the series values on a different axis in the same figure window.

Cell array of Series objects

Plots all series objects with commensurate units on the same axis (superimposed), and each dimension for a nonscalar series on a different axis in the same figure window.

The input arguments are binned based on commensurate units. For each bin, all Series objects with the same dimension as the first Series object in that bin are plotted and others are ignored.

Name-Value Pair Arguments

Specify optional comma-separated pairs of Name,Value arguments. Name is the argument name and Value is the corresponding value. Name must appear inside quotes. You can specify several name and value pair arguments in any order as Name1,Value1,...,NameN,ValueN.

Example: fh = plot(simlog.Translational_Spring.R.v.series,'units','mm/s') plots velocity of port R of the Translational Spring block in mm/s.

Plot legend, specified as the comma-separated pair consisting of 'names' and a cell array of character vectors or string scalars. The number of elements in the cell array must be same as the number of elements of series.

By default, plots have no legend.

Time range for plotting the data, specified as the comma-separated pair consisting of 'time' and a 1x2 vector, [start_time end_time], in seconds.

[] plots all data.

Units for plotting the data, specified as the comma-separated pair consisting of 'units' and a unit name, or a cell array of unit names. Unit names must appear inside single quotes ('') or double quotes (""). Specified units must be commensurate with the units of the series values.

Output Arguments

collapse all

Handles to the resulting plot figure windows, returned as a cell array.
