Calculating area under the curve in python for two given arrays:

I'm using the following code to graph a DF/F signal. I'm hoping to be able to calculate the area under the curve for y = ch1dff and any given x (downsamp_time) range as the limit. I can't seem to find ant code that allows for integration without a function. See plot

plt.figure(figsize=(10,5))
plt.plot(downsamp_time, ch1dff , color='g',label= '465 nm DF/F',)
plt.legend()
plt.xlim([2154, 2334])

markers = m
for marker in markers:
    plt.axvline(x=marker,alpha = 0.2)

What is your question? – mkrieger1 Feb 26 '20 at 17:49
I just can't seem to be able to find any code or package that lets you integrate a curve without a given function. Both "downsamp_time" and "ch1dff" are 1D arrays. – Armin Tavakkoli Feb 26 '20 at 17:53
If you didn’t find any code, what is stopping you from writing it yourself? – mkrieger1 Feb 26 '20 at 18:07
