You can use Simpsons rule or the Trapezium rule to calculate the area under a graph given a table of y-values at a regular interval.
Python script that calculates Simpsons rule:
def integrate(y_vals, h):
i = 1
total = y_vals[0] + y_vals[-1]
for y in y_vals[1:-1]:
if i % 2 == 0:
total += 2 * y
else:
total += 4 * y
i += 1
return total * (h / 3.0)
h is the offset (or gap) between y values, and y_vals is an array of well, y values.
Example (In same file as above function):
y_values = [13, 45.3, 12, 1, 476, 0]
interval = 1.2
area = integrate(y_values, interval)
print("The area is", area)
