Hello everyone,
I should change the colour of red data: on the right I should use a color and on the left another one; is it possible?
Thank you!

Hi Pul,
If you would like to color the vertical bars in an errorbar plot individually, you could try replicating the errorbar plot using the below script:
%Create dummy data and errors
x=1:30;
y=rand(length(x),1);
e=rand(length(x),1);
%Sprinkle some NaNs over the error data
e(randi(max(x),[1 10])) = NaN;
%Plot the data
figure
plot(x,y,'c');hold on;
%Choose length of the whisker for errorbars
inc = 0.25;
for i=1:length(x)
%Set your special condition to switch colors for the vertical bars
if mod(i,2) == 0
color = 'r';
else
color = 'k';
end
%Plot the vertical bar
plot([x(i) x(i)],[y(i)-e(i) y(i)+e(i)],'Color',color);
%Plot the whiskers
plot([x(i)-inc x(i)+inc],[y(i)-e(i) y(i)-e(i)],'Color',color);
plot([x(i)-inc x(i)+inc],[y(i)+e(i) y(i)+e(i)],'Color',color);
end
You could replace x,y and e with your data and set your criteria to color each bar differently. I hope this helps.
