MATLAB: How to plot this graph

graphMATLABplotting

I want to plot such a graph. The upper domain of the shaded area is Mean+Standard deviation and the lower one is Mean-Standard deviation. The yellow line is Mean. Both the CUE and Latitude are column vectors with 3794932 elements each. How to proceed with it on MATLAB? Kindly help me.

The below code could be helpful in plotting the graph.
load data
x=data.Latitude;
y=data.CUE;
std_dev=std(y); %calculate standard deviation
curve1=y+std_dev; %above curve
curve2=y-std_dev; %below curve
x2=[x, fliplr(x)];
Middle=[curve1, fliplr(curve2)];
fill(x2,Middle,'g'); %plot the shaded area between curves
hold on;
plot(x,y,'y','LineWidth',2); %plot the mean line
