MATLAB: Axes units normalized position

image processing

Hi there, if i possible i'd like a brief explanation of these lines below

ha = axes('units','normalized','position',[0 0 1 1]);
uistack(ha,'bottom');

Thanks.

The command axes creates an axes object (see: doc axes). It is created with 'normalized' units, such that the position [0,0,1,1] fills the complete window: Start at point 0,0 in the left bottom and use the full width and height.

Then uistack move this axes object below all other axes, such that it is in the background and does not cover other axes. See: doc uistack .

MATLAB: How to have a graph with labeled x-axis ticks on the bottom and top of the graph

By default the plot should have a set of axes with a labeled set of tick marks on the bottom and the left. The example below explains how this can be done for both the X and Y axes with different Tick labels on all four sides.

plot(1:10);
% First, store the handle to those axes.
% Next create a second set of axes, 
% position This on top of the first and make it transparent.
ax1=gca;
ax2 = axes('Position', get(ax1, 'Position'),'Color', 'none');
set(ax2, 'XAxisLocation', 'top','YAxisLocation','Right');
% set the same Limits and Ticks on ax2 as on ax1;
set(ax2, 'XLim', get(ax1, 'XLim'),'YLim', get(ax1, 'YLim'));
set(ax2, 'XTick', get(ax1, 'XTick'), 'YTick', get(ax1, 'YTick'));
OppTickLabels = {'a' 'b' 'c' 'd' 'e' 'f' 'g' 'h' 'i' 'j' 'k'}
% Set the x-tick and y-tick  labels for the second axes
set(ax2, 'XTickLabel', OppTickLabels,'YTickLabel',OppTickLabels);

MATLAB: Is it possible to get axis size in px units if it is created in normalized units

set(gcf, 'units', 'normalized', 'position', [0 0 1 1]);
AxesH = axes('units', 'normalized', 'position', [0 0 1 1]);
drawnow;   % !!!!!
backUnits = get(AxesH, 'units');
set(AxesH, 'Units', 'pixels')
pixPos = get(AxesH, 'Position');
set(AxesH, 'Units', backUnits);

Without the drawnow I get my full monitor resolution, although Matlab crops the height to display the upper part of the border and the menu bar. What a pity.

A simpler method with a built-in Matlab function:

pixPos = getpixelposition(AxesH)
