errorbarxy

Customizable error bar plot in X and Y direction

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.
