Print all Sub charts in a Stateflow model to individual files

Hello Matlab Forum,

I'm having an issue printing sub charts to file. I essentially want to open all Sub Charts in a Stateflow diagram and print them individually to pdf files for a large model, I thought this would be easy, but it only seems easy to work for charts. Nothing more than opening up all charts and doing a automatic "Print -> Print to File -> PDF"

The following (using a matlab example will work for a chart but not for a sub chart) if you pass in a sub chart on a state it errors and falls over, in this case I would pass '-isa' a 'Stateflow.State' but ensure it is a sub chart too.

Any ideas/ alternates greatly appreciated, I've been stuck on this a while. I might have to resort to producing a docx through the Reporting API and parsing through that in VBA, or using the clipboard somehow maybe, don't really want to open and close a ton of windows though.

chart = find(sfroot, '-isa','Stateflow.Chart','Name','Gear_logic');
chart.fitToView;
chartHandle = get_param(string(chart.Path) +'/','Handle');
sfprint(chartHandle, 'jpg')

I can display charts on screen as shown below, but I can't export them to file using print of sfprint, what am I missing: -

chartColl = find(sfroot, '-isa', 'Stateflow.State', '-and', 'IsSubchart', 1 );
for i=1 : length(chartColl)
     chart= chartColl(i,1);
     %chart.fitToView;
     chart.view;
     print ('c:\temp\testy.pdf','pdf');
     %print '-dpdf' + ' C:\Temp\' + string(chart.id) + '.pdf';
     %dump the image/ file in the clipboard somehow
     %sfprint(gcb,'pdf', 'C:\Temp\' + string(chart.id) + '.pdf',0);
     %chtHand= get_param(string(chart.Path) + '/', 'Handle');
     %sfprint(chtHand,'pdf', 'C:\Temp\' + string(chart.id) + '.pdf');
end

Cheers for any help

Hi Richard,

I'm not quite sure that this is what your are looking for, but maybe this could help. You don't need to pass a handle to sfprint, you can directly pass the object, and I think that you could simply do this:

allSubcharts = find(sfroot, 'IsSubchart',1);
for idx=1:length(allSubcharts)
    sfprint(allSubcharts(idx), 'jpg');
end

For some reason the internet and the help pointed me at saveas which didn't work for me. Nothing pointed me at sfprint until I raised a case. That came back using the handle technique so I didn't twig I could just use an object. Thanks for the correction!!
