MATLAB: How to create horizontal error bars in MATLAB

barerrorhorizontalMATLAB

The "errorbar" function can only create error bars in the vertical direction, but I would like to create horizontal ones.

Best Answer

The ability to create horizontal error bars was added in MATLAB R2016b. You can specify the "ornt" (orientation) property of the plot to be "horizontal" to generate horizontal error bars.

For release R2016a or older

The ability to create horizontal error bars is not available in previous releases. As a workaround, you can download the user-contributed "herrorbar" function from the MATLAB Central File Exchange. You can find this file at the following URL:

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);

MATLAB: How to make a bar chart with error bars in MATLAB 7.7 (R2008b)

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:
