MATLAB: Can I create a custom background for a plot

backgroundcolorplotting

Hello all,
I like to turn my axes and markers off like this:
set(gca,'Visible','off')
Then I change the background to a certain color. My question is can you make the background multicolored? i.e. the color fades from white to black top to bottom or something along those lines. My first instinct is just make an image and put it behind the data I'm plotting, but I was hoping you guys might now of a better way.
If I do have to go the image route what is the code to hide it behind the data. uistack? What would that look like?
Thanks! And let me know if this question needs more explanation.

Which background? Of the axes or the complete figure? This creates a 2nd axes containing a grey ramp behind an invisible axes containing a 2D diagram:
figure;
AxesH = axes('Visible', 'off', 'NextPlot', 'add');  % Axes for diagrams
plot(1:10, rand(10, 10), 'LineWidth', 3);
set(AxesH, 'units', 'pixels');                      % Get size in pixels
Pos  = get(AxesH, 'Position');
ramp = repmat(linspace(1, 0, Pos(4)).', 1, Pos(3)); % Create gray ramp
ImgAxesH = axes('Visible', 'off');                  % Axes for background
imshow(ramp, [], 'Parent', ImgAxesH);               % Show ramp
uistack(AxesH, 'top');                              % Diagram to the top
