How do I add a logo image into a plot or a figure?

I need to add a logo into the plots and graphs that I generate. I need to import a jpeg, tiff or a png file and place (inset) it in the bottom left corner of the plot.

There ability to directly add logos or images in a plot does not exist in MATLAB.

As a workaround the following code can be used.

% Test Code to set a logo into figures(plots and graphs)

clear

close

% create the plot/graph

plot(rand(10));

% GET handle to current axes and move the plot axes to the bottom

ha =gca;

uistack(ha,'bottom');

% Creating a new axes for the logo on the current axes

% To create the logo at the bottom left corner of the plot use 

% the next two lines

haPos = get(ha,'position');

ha2=axes('position',[haPos(1:2), .1,.04,]);

% To place the logo at the bottom left corner of the figure window

% uncomment the line below and comment the above two lines

% ha2=axes('position',[0, 0, .1,.04,]);

% Adding a LOGO to the new axes

% The logo file(jpeg, png, etc.) must be placed in the working path

[x, map]=imread('peppers.png');

image(x)

% Setting the colormap to the colormap of the imported logo image

colormap (map)

% Turn the handlevisibility off so that we don't inadvertently plot

% into the axes again. Also, make the axes invisible

set(ha2,'handlevisibility','off','visible','off')
