I do have much noise in the data from a test. So my graph doesn't look good. y axis data are consistent however x axis data have fluctuation. How can I smooth the graph like the black graph in the picture keeping the maximum value of y in matlab?

I think there is a seperate tool; box for this purpose(Curve Fitting Toolbox). Check it out.

A moving average filter might do the job. Play around with the number of points to preserve the peak value.
N = 10;
h = (1/N)*ones(1,N);
filtered = conv(orginal, h);
filtered = filtered(N:end);
