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.

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'));

For your model, open the Metrics Dashboard.

metricsdashboard vdp

Click the All Metrics button to run all metrics.
