How can I plot 2 graphs with errorbar each one?

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)

Please light me with your wisdom @Walter Roberson =(

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');
