I have data in CSV file, I am extracting data using iloc into variables. So I have 2 series one is the data and the other is time. I want to derivate the data with respect to time and then plot the Derivate data.
DY=misc.derivative(YR,TR)
plt.plot(DY)
plt.show()I am getting this errorTypeError: 'Series' object is not callableYR and TR are Panda Series I am getting this output by print(YR) and Print(TR)

Look at the function signature of misc.derivative: https://docs.scipy.org/doc/scipy/reference/generated/scipy.misc.derivative.html
The first argument is a callable, which is why you get the Series not callable error. Scipy.misc.derivative seems to be used for evaluating derivatives of an analytical function numerically, which is not what you are attempting to do. It seems like you want to do some stenciling to approximate derivatives instead.
