Ok, app.BS is a uitable. app.BS.Data is the information displayed in that uitable.
What I would do, then, is create a property in the app to hold the raw data loaded from BS.txt.
properties (Access = private)
data % raw data from text file
end
I would add a new variable summing Var2 and Var3 to it (I called it app.data). Then I would plot Var1 vs this new variable.
% Button pushed function: ChooseButton
function ChooseButtonPushed(app, event)
[filename, pathname] = uigetfile({'*.txt'}, 'File Selector');
app.data = readtable (fullfile(pathname, filename), 'HeaderLines', 0);
app.BS.Data = app.data;
app.BSEditField.Value = filename;
end
% Button pushed function: DisplayButton
function DisplayButtonPushed(app, event)
app.data.sumVars = app.data.Var2+app.data.Var3;
plot(app.UIAxes, app.BS.Data.Var1,app.data.sumVars)
end
