~do calculations
x=ddata;
y = edata;
handles=guidata(hObject);
[X,Y] = peaks;
surf(X,Y);
xlim([-inf inf]);
ylim([0 inf]);
plot(x,y,'parent',handles.axes1);
hold on
plot(x_mark,y_mark,'c*',handles.axes1)
hold off
the x_mark and y_mark are both in array that I got from a while loop. I made a GUI that plots the figure

How do I mark (with a dot or asteroid and different color) my (x_mark,y_mark) points on the (x,y) points on my graph?
The (x_mark,y_mark) are specific points on the (x,y) graph that I want to highlight.
The code is plotting (x,y) first and then plotting (x_mark,y_mark)

Example:
x = 1:10;
y = rand(1, 10);
s = [2,4,8]; % Indices of points to mark
plot(x, y);
hold on
plot(x(s), y(s), '*')

So basically I mapped coordinates on a graph. I then did a calculation to find the stopping point every 8hrs which I saved into x_mark and y_mark. I then want to have these points marked/highlighted on the graph

@hi hey: This explanation does not help to understand "That didn't work" and why which points are shifted vertically. If you still need help, please post something, which let the readers reconsider, what's going wrong: code, input data, screenshot of the diagram, ...
