Read about subplot, montage. If not show us your requirement clearly.

hi,
It seems like you want to put in gray scale and histogram, I think you are working in image processing. One can use hold on if you are plotting only two images on each other and adjust the transparency.
you can try subplot if there are multiple images that needs to be displayed.
I found this on file exchange: This reduces the gap between two plots in matlab.

Ran in:
clc; clear all; close all;
% I plot image and get multiple figures gray scale, histogram like wise,
% I need to take this separate figures in same frame with labels.
fs = {'football.jpg', 'rice.png', 'cameraman.tif'};
for i = 1 : numel(fs)
fi = fs{i};
imi = imread(fi);
imio = imi;
if ndims(imi) == 3
imi = rgb2gray(imi);
end
figure(i);
subplot(2,2,1); imshow(imio); title([fi ' origin']);
subplot(2,2,2); imshow(imi); title([fi ' gray']);
subplot(2,2,3); imhist(imi); title([fi ' hist']);
end
