Customizable error bar plot in X and Y direction

| Watch this File

File Information
Description

PLEASE NOTE:
A similar Matlab function, ploterr (FEX ID #22216), does all what this function does, plus some more. It should be preferred over this submission, which then might be deleted in a near future.

This function allows the user to plot the graph of x against y, along with both x and y errorbars.
With 4 numeric arguments (x,y,dx,dy), error bar are assumed to be of same magnitude in both direction.
One can specify lower and upper error bar with 6 numeric arguments (x,y,dx_high,dy_high,dx_low,dy_low).
x,y,dx,dy,... must be vectors of the same length.

[hp he] = errorbarxy(...) returns respectively the handle for the line plot object and the line error bar object.

It is possible to customize the line properties of the error bars by adding pair of 'field/value' fields (such as 'LineWidth',2) that can be understood by line. See LineProperties for more information.

--------
EXAMPLES
--------
X = 10 * rand(7,1);
Y = 10 * rand(7,1);
dx = rand(7,1);
dy = rand(7,1);
errorbarxy(X,Y,dx,dy,'Color','k','LineStyle','none','Marker','o',...
'MarkerFaceColor','w','LineWidth',1,'MarkerSize',11);

X = 10 * rand(7,1);
Y = 10 * rand(7,1);
dx = rand(7,1);
dy = rand(7,1);
dx2 = rand(7,1);
dy2 = rand(7,1);
errorbarxy(X,Y,dx,dy,dx2,dy2,'Color','B','LineStyle','--','Marker','s',...
'MarkerFaceColor','w','LineWidth',2,'MarkerSize',11);

This is a rewrite of the m-file errorbarxy of James Rooney, to add customizable line properties.

very good

I found this function behaves oddly if the dx, dy, dx2 and dx2 vectors have negative values in them. Also it would be helpful if the doc described the return outputs. When apply legends to graphs you get two entries one for the data points and one for the error bars. This is easy to prevent as follows:

h = errorbarxy(x,y,dx,dy,dx2,dx2)
legend(h(1),'legend text')

didn't work at first, but then started by editing examples, and it worked. thanks.

I still cannot find the missing function...

Error corrected, missing subfunction included in the file. Thanks to Brad Ridder for reporting.

It doesn't work.

Undefined function varargin2struct()

Put a more recent with decent help version.

Desperately trying to post the CORRECT file.

21 Apr 2008

Missing subfunction struct2varargin is now included in the file. Thanks to Brad Ridder for reporting it.

From Keith Brady feedback, prevent oddities when entering negative error bar length

11 Feb 2009

Corrected minor bugs + updated picture

19 Feb 2009

Added a reference to the FEX ID #22216 which does similar thing, in a much complete and better way.
