Hello, how can I create a yes & no button to a question that I want to prompt the user's answer to and then also store whether the user clicked yes or no?

Hermione - try using questdlg to create a question with the yes or no answer. Something like
dlgTitle = 'User Question';
dlgQuestion = 'Do you wish to continue?';
choice = questdlg(dlgQuestion,dlgTitle,'Yes','No', 'Yes');
choice will be a string for 'Yes' or 'No'.

HC, regarding your followup question/comment, try this:
promptMessage = sprintf('Is Image Analyst awesome?');
titleBarCaption = 'Yes or No';
numberOfUsers = 4;
buttonSelections = zeros(1, numberOfUsers); % Preallocate.
for userNumber = 1 : numberOfUsers
button = questdlg(promptMessage, titleBarCaption, 'Yes', 'No', 'Yes');
if strcmpi(button, 'Yes')
buttonSelections(userNumber) = 1;
else
buttonSelections(userNumber) = -1;
end
end
% Report their choices to the command window:
buttonSelections
% Plot a bar chart
bar(buttonSelections);

Hi Image Analyst, thank you for your input! However, what if I want to save the users' yes & no answer to a file for example an excel file and then extract this file onto a graph because the yes & no answers are only for x axis, y axis will be something completely different.
You can use xlswrite(filename, {'Yes'}, 'A1') to save a "yes" to a file. You can use xlsread() to read it back in.

question = menu('Whatever your question is?', 'Yes', 'No')
This will pop up as a little menu in which you can select yes or no as a button. The Yes values are stored as 1's and the No values are stored as 2's.
And then to store the answers you can store whether they selected 1 or 2 and find the data from there.

Hi Samantha, thank you for your help! with your suggestion, how would I modify that so I can prompt multiple user's answers and store them separately? Because it seems like the second time I run it and click no as opposed to yes, it erased my yes input the first time. And also, how would i use all of these data i collected and make it to a graph?
