[Octave-bug-tracker] [bug #36480] No markers in Legends with errorbar-plot

[Carnë Draug]

Follow-up Comment #2, bug #36480 (project octave):

I can confirm this bug is still present (also seems a regression from  bug
#29057). This can be seen easily by comparing the following:


figure ();
x = -10:0.5:10; plot (x, sin (x), "-ob", x, cos (x), "-xb"); legend ("sin
(x)", "cos (x)");
figure ();
x = -10:0.5:10; errorbar (x, sin (x), 0.5, "-ob", x, cos (x), 0.5, "-xb");
legend ("sin (x)", "cos (x)");


On the first figure (where plot() was used), the legend shows the marker,
while on the second (done with errorbar()), ther is only the text.

I'm not super familiar with the code for graphics but I tracked it down to
somewhere before line 840 of legend.m


              marker = get (hplots(k), "marker");


where this returns "none" for an errorbar plot. This however is not true as
can be seen from:


x = -10:0.5:10; h = plot (x, sin (x), "-ob", x, cos (x), "-xb");
get (h, "marker")
x = -10:0.5:10; h = errorbar (x, sin (x), 0.5, "-ob", x, cos (x), 0.5,
"-xb");
get (h, "marker")
