I guess the points in the plot are not arranged in a correct order. So it goes from upper to the lower curve and vice versa.

It looks like the polarity of your signal is occasionally flipping. Assuming the signal is initially analog and passing through an analog-to-digital converter, you may be able to fix this for future data by tinkering with the A:D converter or during down the gain of the analog signal.
You can also fix this in post-processing (in MATLAB) if you can asssume that the polarity shouldn't suddenly switch.
The rule you would follow would be that if s(n+1) has a different sign than s(n) and s(n) is not sufficiently near 0, then flip the sign of s(n+1), where s is your signal.
