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.

When using a log scale, the error bars don't look right. Any quick fix for this?

very good

Keith Brady

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...

Jean-Yves Tinevez

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

It doesn't work.

Undefined function varargin2struct()

Updates

1.3

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

1.2

Corrected minor bugs + updated picture

1.1

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

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

Desperately trying to post the CORRECT file.

Put a more recent with decent help version.
