I've added Dan Sebald to the CC list since he is the main programmer of the interface to gnuplot.

I also modified the example to see more clearly what is going on.


close all
graphics_toolkit gnuplot
a=linspace(1,10,20);
b=sin(a);
myerr=a*0+0.1;
h1=errorbar(a,b,myerr);
set(h1,"linestyle",'--',"linewidth",2,"color",'red',"marker","x",'markersize',8);
legend("test");
h = copyobj (1);
graphics_toolkit (h, "fltk");


This is attached as the file tst_errbar_gnuplot.m

When gnuplot_draw_axes.m from mercurial is used with 4.2.1 release to fix the bug #50473: (plotting with errorbar: duplicate legend entries)
leads to another problem: marker symbol is not shown in the legend when errorbar.m is used. The following code demonstrates the problem:

graphics_toolkit gnuplot
a=linspace(1,10,100)
b=sin(a);
myerr=a*0+0.1
h1=errorbar(a,b,myerr)
set(h1,"linestyle",'--',"linewidth",5,"color",'red',"marker","*",'markersize',12);
legend("test");

if plot is used instead of errorbar, the problem is not present.
