if i use Zoom xon,we cant make it to zoom by some factor
say(0.5x,1x,etc,..)by itself.
i ve one axes and 4 push buttons, when i click the first
button the axes will zoom(horizonally) by 0.5%,second
button 1%,third button 2%,then forth button 4%... is this
possible?

Example:

function slidertp
load clown
h = figure,imshow(X,map);
h1 = uicontrol('Style','Slider','Callback',{@myzoom,h});

function myzoom(obj,event,h)
val = get(obj,'Value');
if isempty(get(obj,'UserData'))
    val_temp = val;
    set(obj,'UserData',val_temp);
else
    val_temp = get(obj,'UserData');
end
if val>=val_temp
    zoom(h,1.01);%zoom factor
    val_temp = val;
    set(obj,'UserData',val_temp);
else
    zoom(h,0.99);%zoom factor
    val_temp = val;
    set(obj,'UserData',val_temp);
end
