# Enlarge figure in MATLAB

I want to create figure that is enlarged, I use:

fig = figure(1);%These two lines maximize the figure dialogue
set(fig,'Units','normalized','Position',[0,0,1,1]);

Then I use zoom(1.9); to enlarge the figure

The dialogue is enlarged. But I want to reposition it just like use the "pan" button. How can I do it programmatically?

Related MATLAB, Maple, Mathematica, LaTeX News on Phys.org
Most new versions of Matlab can generate a script for button function.

Actually my problem is still not solved.
Here's update of my question:
I am trying to plot 3D block which the value is represented by color of each small unit block:

clear; close all; clc;
fig = figure(1);
set (fig, 'Units', 'normalized', 'Position', [0,0,1,1]);
fig_color='w'; fig_colordef='white';
cMap=jet(256); %set the colomap using the "jet" scale
faceAlpha1=1;
faceAlpha2=0.65;
edgeColor1='none';
edgeColor2='none';
NumBoxX=100;%box number in x direction
NumBoxY=100;%box number in y direction
NumBoxZ=5;%box number in z direction

fid = fopen('Stress.dat','r');
datacell = textscan(fid, '%f%f%f%f%f%f%f%f%f%f%f%f%f%f');
fclose(fid);

all_data = cell2mat(datacell);

M=zeros(NumBoxX,NumBoxY,NumBoxZ);

for i=1:NumBoxX
for j=1:NumBoxY
for k=1:NumBoxZ
num=k+NumBoxZ*(j-1)+NumBoxZ*NumBoxY*(i-1);
M(i,j,k)=all_data(num,4); %the forth column of all_data is dislocation density
end
end
end

indPatch=1:numel(M);
[F,V,C]=ind2patch(indPatch,M,'v'); %Call the function ind2patch in order to plot 3D cube with color

title('\sigma_{xy}','fontsize',20);
xlabel('y','fontsize',20);ylabel('x','fontsize',20); zlabel('z','fontsize',20); hold on;
set(get(gca,'xlabel'),'Position',[5 -50 30]);
set(get(gca,'ylabel'),'Position',[5 50 -15]);
set(get(gca,'zlabel'),'Position',[64 190 -60]);
patch('Faces',F,'Vertices',V,'FaceColor','flat','CData',C,'EdgeColor','k','FaceAlpha',0.5);
axis equal; view(3); axis tight; axis vis3d; grid off;
colormap(cMap); caxis([min(M( max(M( ]);
cb = colorbar;
set(get(cb,'title'),'string','Stress (MPa)','fontsize',20);
lbpos = get(cb,'title'); % get the handle of the colorbar title
set(lbpos,'units','normalized','position',[0,1.04]);
zoom(1.9);

I maximize the dialogue, read data from a file and use a function "ind2patch" found in internet to create boxes each has a color determined by a value assigned to it. At the last part I used zoom(1.9) to enlarge it but I want to shift the whole figure without moving the colorbar.
The following is the original picture before zoomed:

The following picture is enlarged using zoom(1.9):
