MATLAB: How to add a description text on top of a plot without it being written all of the plot

Question

How to add a description text on top of a plot without it being written all of my plot ?

here is my code just run it to understand what I mean.

is it possible to translate the plot to the bottom?

FigH = figure;
plot(1:10)
AxesH = axes('Parent', FigH, ...
  'Units', 'normalized', ...
  'Position', [0, 0, 1, 1], ...
  'Visible', 'off', ...
  'XLim', [0, 1], ...
  'YLim', [0, 1], ...
  'NextPlot', 'add');
chr = 'I wanna add a description';
chr = [chr newline 'On top of the plot']
TextH = text(0,1, chr , ...
  'HorizontalAlignment', 'left', ...
  'VerticalAlignment', 'top');

Why not just reduce the height of your first axes a little? See the comments below (I also made some additional improvements).

FigH = figure();
axh = axes(FigH); 
axh.Position(4) = axh.Position(4) * .9;    % <--- reduce height by 10%
plot(axh, 1:10)
AxesH = axes('Parent', FigH, ...
  'Units', 'normalized', ...
  'Position', [0, 0, 1, 1], ...
  'Visible', 'off', ...
  'XLim', [0, 1], ...
  'YLim', [0, 1], ...
  'NextPlot', 'add');
chr = sprintf('I wanna add a description\nOn top of the plot'); 
TextH = text(AxesH, 0,1, chr , ...
  'HorizontalAlignment', 'left', ...
  'VerticalAlignment', 'top');
