How to calculate the area of the positive part of a graph in python?-CodePudding

I have a dataframe

>>print(df)
                          Power
timestamp

2019-02-16 23:00:00  -7432.0824

If I plot them I have:

df.plot()

Based on the comment:

s = [0,5,-1,0,0,-1,5,0]
s = [x for x in s if x>=0]
plt.plot(s)
np.trapz(s)

Output:
