Hi, I have a confidence interval (CI) I would like to plot together with its average. I have used the command fill to create the grey CI area and don't get the results that I want. My data is

mu_diff
0.004228176
-0.000889339
-0.016775836
-0.023576712
-0.041489385
-0.050768254
-0.621729693
-0.634756996
-0.640305162
-0.648905396
CI	
0.004041487	0.004414864
-0.001080781	-0.000697896
-0.016971981	-0.016579692
-0.023777484	-0.02337594
-0.041694683	-0.041284086
-0.050977948	-0.050558559
-0.621943623	-0.621515762
-0.634974968	-0.634539023
-0.640526947	-0.640083377
-0.649130726	-0.648680066

and the lines I have written are

x_axis = 61:70;
x_plot =[x_axis, fliplr(x_axis)];
y_plot=[CI(:,1)', flipud(CI(:,2))'];
hold on
plot(x_axis, mu_diff, 'black', 'linewidth', 1)
fill(x_plot, y_plot, 1,'facecolor', 'red', 'edgecolor', 'none', 'facealpha', 0.4);
hold off

and this is the result

Clearly this is not correct. What is going wrong here?

Nothing wrong, you just happen to have very narrow confidence bounds.

Thanks for that :) I found the magnifier glass too, will be using it from now on.
