You can use the handle of the uitable to get the data inside it in the form of a table object

data = app.UITable.Data;

app.UITable is the handle of the uitable in app designer. Change it according to the name of you uitable.

You can call the button pushed callback function programmatically, so if your callback looks like this,

 % Button pushed function: Button
 function ButtonPushed(app, event)
     % Do something       
 end

you can call it by the following.

ButtonPushed(app, matlab.ui.eventdata.ButtonPushedData)

Matt's answers are the preferred ways, but he happened to overlook a possibility to do what you showed:

set(pb1, 'Callback', ...
 ['plot(subsref(load(''SomeMatFile'',''variable1''), ', ...
         'struct(''type'', ''.'', ''subs'', ''variable1''))' ] );

That is, the Callback can be set to a string that will be executed in the "base workspace". The command indicated by the string loads variable1 from the file, and returns a structure array that has variable1 as a field name; the field is then extracted by the subsref call, and the data that results is then plotted by plot().

You might even be able to use a string that has multiple commands separated with ';', but I have not experimented with that myself. I avoid using this kind of callback construction, doing so only when the alternatives are worse.
