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?
