Hello,
I'm calculating and plotting a mean-Values and standard deviation:
If I plot it via errorbar, I get:
....
errorbar(M1(:,2),M1(:,1),S1(:,2),S1(:,1),'-o','both','LineWidth',1.5,'MarkerFaceColor','cyan','MarkerSize',10,'MarkerEdgeColor','black','DisplayName',label1{1})
....
errorbar(M2(:,2),M2(:,1),S2(:,2),S2(:,1),'-s','both','LineWidth',1.5,'MarkerFaceColor','yellow','MarkerSize',10,'MarkerEdgeColor','black','DisplayName',label2{1})
...
If I plot with errorbarxy function, I get:
errorbarxy(M1(:,2),M1(:,1),S1(:,2),S1(:,1))
....
errorbarxy(M1(:,2),M1(:,1),S1(:,2),S1(:,1))
....
Why, I'm getting different line length? I tnink an errorplot has a wrong length, because there are each one value for x-axis and y-axis?! What is the better way to plot main + std?
values are:
M1 =
0.0570 0.9098
0.0860 0.8615
0.7741 0.1542
0.9682 0.0200
0.9874 0.0016
M2 =
0.0591 0.9049
0.2164 0.7222
0.7954 0.1332
0.9703 0.0091
0.9761 0.0082
S1 =
0.0196 0.0220
0.0356 0.0585
0.0349 0.0636
0.0354 0.0347
0.0027 0.0027
S2 =
0.0323 0.0461
0.2140 0.2619
0.2021 0.1885
0.0216 0.0158
0.0171 0.0141

Sorry, it was to late and my brain was down.
I have a solution with standard errobar:
errorbar(M2(:,2),M2(:,1),S2(:,2),S2(:,2),S2(:,1),S2(:,1),'-s','LineWidth',1.5,'MarkerFaceColor','yellow','MarkerSize',10,'MarkerEdgeColor','black','DisplayName',label2{1})
I have to define xpos and xneg, ypos and yneg
So just scribe the same two times =)

See this example from the documentation for errorbar.

Yes, thank you! I solve it by writing two time a values for xpos and xneg, ypos and yneg =)
