Dear community
I'm plotting 2 graphs and I want to put errorbar in each plot.
How can I do that?
Thanks!

Use errorbar and hold on or as per the documentation, if y is a matrix errorbar plots a separate line for each column.

i'm using this script
hold on
err_C = [(Voc_desv_C)];
x = linspace(0, 50, numel(Voc_C));
errorbar(x,Voc_C,err_C)
err_D = [(Voc_desv_D)];
x = linspace(0, 50, numel(Voc_C));
errorbar(x,Voc_D,err_D)
y1 = Voc_C;
y2 = Voc_D;
plot(x,y1,x,y2)
xticks(1:50);
title('Voc Plot')
xlabel('Tiempo (Días)')
ylabel('Voc (V)')
legend('Voc Clean','Voc Dirty');
And appers a third color (purple) and (I think) asume the legend to errorbar of each one (not to y1 and y2)

Why are you using plot to draw the same data as are drawn with errorbar?
x = linspace(0, 50, numel(Voc_C)); % x points vector (row)
X = [x;x].'; % 2-column X to plot against
Y = [Voc_C(:) Voc_D(:)]; % 2-column Y to plot
err=[Voc_desv_C(:) Voc_desv_D(:)]; % 2-column error to plot
errorbar(X,Y,err)
title('Voc Plot')
xlabel('Tiempo (Días)')
ylabel('Voc (V)')
legend('Voc Clean','Voc Dirty');
