Enlarge figure in MATLAB

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

fig = figure(1);

set (fig, 'Units', 'normalized', 'Position', [0,0,1,1]);

The dialogue is enlarged. What should I do if I also want the graph inside this dialogue also enlarged? Although I can use "zoom in" and "pan" in the dialogue to enlarge and reposition my graph I want this be done automatically by codes.

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;

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);

• You either want to set the units of the axes also to normalized, before setting the position of figure
• or you want to set the SizeChangedFcn of the figure and handle there what you want to do

fig.SizeChangedFcn = @(source,event) mySizeChangedFcn(source,event);

actually it is not a 2D plot, I used a function called ind2patch to make a 3D block which contains a number of smaller blocks in 3 dimensions. When I use xlims I just found that the x axis is extend but the figure is not enlarged.

 I updated my question above by adding my codes.
