## Plot data with error bars on both x and y axes

Version 1.81.0.0 (3.58 KB) by
plot data with error bars along both x and y axes

ERRORBARXY is a function to generate errorbars on both x and y axes
with specified errors modified from codes written by Nils Sjöberg
(http://www.mathworks.com/matlabcentral/fileexchange/5444-xyerrorbar)
errorbarxy(x, y, lerrx, uerrx, lerry, uerry) plots the data with errorbars on both
x and y axes with error bars [x-lerrx, x+uerrx] and [y-lerry, y+uerry]. If there is
no error on one axis, set corresponding lower and upper bounds to [].
errorbarxy(x, y, errx, erry) plots the data with errorbars on both x and
y axes with error bars [x-errx, x+errx] and [y-erry, y+erry]. If there
is no error on one axis, set corresponding errors to [].
errorbarxy(..., S) plots data as well as errorbars using specified
character strings. S is a cell array of 3 element, {sData, cEBx, cEBy},
where sData specifies the format of main plot, cEBx specifies the
color of errorbars along x axis and cEBy specifies the color of
errorbars along y axis.
errorbarxy(AX,...) plots into AX instead of GCA.

H = errorbar(...) returns a vector of errorbarseries handles in H,
within which the first element is the handle to the main data plot and
the remaining elements are handles to the rest errorbars.
H is organized as follows:
H.hMain is the handle of the main plot
H.hErrorbar is a Nx6 matrix containing handles for all error bar lines,
where N is the number of samples. For each sample, 6
errorbar handles are saved in such an order:
[Horizontal bar, H bar left cap, H bar right cap,
Vertical bar, V bar lower cap, V bar upper cap]
For example
x = 1:10;
xe = 0.5*ones(size(x));
y = sin(x);
ye = std(y)*ones(size(x));
H=errorbarxy(x,y,xe,ye,{'ko-', 'b', 'r'});
draws symmetric error bars on both x and y axes.
NOTE: errorbars are excluded from legend display. If you need to
include errorbars in legend display, do the followings:
H=errorbarxy(...);
arrayfun(@(d) set(get(get(d,'Annotation'),'LegendInformation'),...
'IconDisplayStyle','on'), H(2:end)); % include errorbars
hEB=hggroup;
set(H(2:end),'Parent',hEB);
set(get(get(hEB,'Annotation'),'LegendInformation'),...
'IconDisplayStyle','on'); % include errorbars in legend as a group.
legend('Main plot', 'Error bars');
