Edit box string to column value plotting
显示 更早的评论
Im attempting to use edit boxes in a GUI as away to destinguish what columns a plot command recognizes as a plot
numdata=xlsread(uigetfile({'.xlsx'},'File Selector'));
x=numdata(:,str2num(handles.XCInput, 'string'));
y=numdata(:,str2num(handles.YCInput, 'string'));
plot (x,y)
XCInput and YCInput are the tags for the chosen text edits

What problems are you having?
Could you provide an example of a string stored in handles. XCInput and YCInput?

What is this syntax supposed to do?:
str2num(handles.YCInput, 'string')

You invented a str2num syntax that does not exist:
str2num(handles.YCInput, 'string')
% ^^^^^^^^^^ is this in the STR2NUM documentation?
Where in the STR2NUM documentation is the 2nd input shown? (hint: nowhere, it does not exist).
If you want to use functions, you need to follow the syntaxes that they actually support:
x = numdata(:,str2num(handles.XCInput));
