MATLAB: How to plot bar graphs with patterns on them using the BAR function in MATLAB

barfunctiongraphshatchMATLABpatternspie

I would like to know how can I plot bar graphs with patterns on them so that I can distinguish among them when I plot the bars in gray scale. For example

Y = round(rand(5,10)*10);
   colormap(gray);
   bar(Y,'group')

The bars would be more distinguishable if they had patterns on them.

The ability to plot bar graphs with patterns on the bars using the BAR function is not available in MATLAB.

There are several user-submitted contributions on the MATLAB Central File Exchange which help work around this issue. One such file can be found here:

There is built-in functionality in MATLAB 7.7 (R2008b) to do this.

An example of how to do this is the errorbar function which can be found at the MATLAB File Exchange at the following page:

MATLAB: How to obtain the coordinates of the mouse on the screen displayed somewhere in the figure window

This enhancement has been incorporated in MATLAB 7.5 (R2007b).

As a workaround in previous MATLAB releases, you can use the following MATLAB function to track mouse motion:

function mousetrk
%MOUSETRK function to track mouse motion
% This function creates two static text controls
% which contain the x & y coordinates of the mouse
% The driving callback is executed by the
% WindowButtonMotionFcn of the figure.
figure
axes('Visible','off')
xbox = uicontrol('Style','text','Tag','xbox');
xboxlabel = uicontrol('Style','text','String','X Value',...
    'Position',get(xbox,'position')+[0 21 0 0]);
ybox = uicontrol('Style','text','Position',[90 20 60 20],'Tag','ybox');
yboxlabel = uicontrol('Style','text','String','Y Value',...
    'Position',get(ybox,'position')+[0 21 0 0]);
callback = ['pt = get(gca,''CurrentPoint'');'...
  'xbox = findobj(''Tag'',''xbox'');' ...
  'ybox = findobj(''Tag'',''ybox'');' ...
  'set(xbox,''String'',num2str(pt(1,1)));' ...
  'set(ybox,''String'',num2str(pt(1,2)));'];
set(gcf,'WindowButtonMotionFcn',callback);
