Um, did you look up "plot" in the help? Did you find anything like this:
plot(X, Y);
Or even fancier:
% Define sample data.
X = [1,2,3,4,5,6,7,8,9];
Y = [4 5 6 9 8 7 4 1 2];
% Do the plotting:
plot(X, Y, 'bo-', 'LineWidth', 3, 'MarkerSize', 15);
grid on;
% Maximize the figure window.
set(gcf, 'units','normalized','outerposition',[0 0 1 1]);
% Label the various parts of the plot.
fontSize = 20;
title('lowcalorie Plot', 'FontSize', fontSize);
xlabel('X', 'FontSize', fontSize);
ylabel('Y', 'FontSize', fontSize);

Worked for me. I can't tell you why it didn't work unless I see your code. Did you put your data inside square brackets like I did? Also, you should add a comment to my answer, not post your comment as a new "Answer" to your question.
