making a title using editable strings without stacking

So, I have this GUI that takes a excel sheet, or CSV file and plots the data inside the sheet. On top of that I have edit boxes that creste labels on the plot of the GUI. The plotting works and the label making works, but I have a check box that add elements to the tile based off what your labels are. saddly, the lements instead of rweading out in one line, stack ontop of eachother

and the code is such

function Excel_Button_Callback(hObject, eventdata, handles)
numdata=xlsread(uigetfile({'.xlsx'},'File Selector'))
x=numdata(:,1);
y=numdata(:,2);
plot(x,y);
xlabel(get(handles.X_Label_Input, 'String'));
ylabel(get(handles.Y_Label_Input, 'String'));
title(get(handles.Title_Input, 'String'));
if (get(handles.VsCheck, 'Value'))==1;
title([get(handles.Title_Input, 'String') get(handles.Y_Label_Input, 'String') 'vs' get(handles.X_Label_Input, 'String') date]);
end

Where is date coming from and what datatype is it? I predict it is string()

I think "date" here is an inbuild MATLAB function which gives current date string as an output

In the code you have shown the second to last line as

title([get(handles.Title_Input, 'String') get(handles.Y_Label_Input, 'String') 'vs' get(handles.X_Label_Input, 'String') date]);

"get" will give you cell array and then you are trying to concatenate cell as a string but instead MATLAB is concatenating it as a cell array. So, to resolve this you can try using "strjoin" to covert cell into string and then concatenate. For more info on "strjoin" you can use:

help strjoin

To get the expected results replace 2nd to last line with the line below :

title([strjoin(get(handles.Title_Input, 'String')),strjoin(get(handles.Y_Label_Input, 'String')),...
    'vs',strjoin(get(handles.X_Label_Input, 'String')),date]);

I hope it helps!

""get" will give you cell array "

Possibly. But if so then one of two circumstances would have to be true:

1. handles.Title_Input would have to be a vector of handles instead of a single handle; or
2. handles.Title_Input would have to have Max > 1 so that it was a multi-line edit box.

When you get the String property of a single uicontrol for which Max is 1, then you get back a character vector
