I want to manually control the x step size (xticks).
there is a edit field which determines the x step size:
xstep1=str2double(get(handles.xstep1,'String'));
this is what i have now
if ~isnan(xstep1)
xbounds = xlim;
set(gca,'XTick',xbounds(1):xstep1:xbounds(2));
end
hope it helps someone

Hi,
You're just trying to change the default XTick position or the XTickLabel? These two is different properties.
My suggestion is first plot a simple figure then using the edit tool in the figure to change whatever you want, and you can get the m-code after the changes. At this point you will know the exact code that meets your need. Here's the steps you can follow:
1. plot(1:10,1:10);
2. click Edit->Axes Properties...on the Figure menu, and click Ticks...button on the opened property panel.
3. Change what you want, then click File->Generate Code on the figure menu.

thank you , I edited my first post.
new question for now:
Matlab creates lines at each xtick, except if there is data in it (graph), now i have to find out how still to show the line even if there is a graph in it.

What do you mean by graph? a picture? or a shape?
I think you should ask a new question if it's totally a different one from this theme, or others won't notice.

example you make a bar graph.
lets say, at 1 there is no bar, so you see a short line at xtick 1, at 2 there is a value so it creates a bar , then that line disappears..
