Syntax

setSeparators(S)

Description

setSeparators(S) specifies whether there are lines on the sides of an slmetric.dashboard.Group object.

Input Arguments

expand all

The input is a structure array consisting of these fields:

  • S.top

  • S.bottom

  • S.left

  • S.right

Each field must be set to 1 or 0. A value of 1 indicates that there is a line on that group side. A value of 0 indicates that there is no line on that group side. To indicate that the group sides are always the same even if the screen size changes, you can pass one structure. Passing four structures indicates that the group sides can have different separators as the screen width size changes. Use the setWidths method to specify up to four different widths.

Data Types: char

Create a custom metric that counts nonvirtual blocks. Specify a widget to display this metric on the Metrics Dashboard. Add it to the Size Group.

Open the model vdp by entering:

openExample('simulink_general/VanDerPolOscillatorExample')

Create a custom metric class.

className = 'nonvirtualblockcount';
slmetric.metric.createNewMetricClass(className);

Create the nonvirtual block count metric by adding this code to the nonvirtualblockcount.m file.

classdef nonvirtualblockcount < slmetric.metric.Metric
    %nonvirtualblockcount calculates number of nonvirtual blocks per level.
    % BusCreator, BusSelector and BusAssign are treated as nonvirtual.

Register the new metric in the metric repository.

[id_metric,err_msg] = slmetric.metric.registerMetric(className);

To begin, open the default configuration for the Metrics Dashboard layout.

conf = slmetric.dashboard.Configuration.open();

Obtain the slmetric.dashboard.Layout object from the slmetric.dashboard.Configuration object.

layout = getDashboardLayout(conf);

Obtain widget objects that are in the layout object.

layoutWidget = getWidgets(layout);

Remove the widget that represents the Simulink block count metric.

sizeGroup = layoutWidget(2); 
sizeGroupWidgets = sizeGroup.getWidgets(); 
sizeGroup.removeWidget(sizeGroupWidgets(1));

Add a widget that displays the nonvirtual block count metric. For custom widgets, the default visualization type is single value. If you want to use a different visualization technique, specify a different value for the VisualizationType property.

newWidget = sizeGroup.addWidget('Custom', 1);
newWidget.Title = ('Nonvirtual Block Count'); 
newWidget.setMetricIDs('nonvirtualblockcount');
newWidget.setWidths(slmetric.dashboard.Width.Medium);
newWidget.setHeight(70);

Specify whether there are lines separating the custom widget from other widgets in the group. These commands specify that there is a line to the right of the widget.

s.top = false;
s.bottom = false;
s.left = false;
s.right = true;
newWidget.setSeparators([s, s, s, s]);

Save the configuration object. This command serializes the API information to an XML file.

save(conf,'Filename','DashboardConfig.xml');

Set the active configuration.

slmetric.dashboard.setActiveConfiguration(fullfile(pwd,'DashboardConfig.xml'));

Open the Metrics Dashboard for the model vdp.
