Data Preparation To prepare data we would be using the numpy arrays as they are easier to handle. We would be plotting a sine wave where x coordinates are the x-axis value and y coordinates are the sine value of x. Webnumpy.interp is defined as like below: numpy.interp(x, xp, fp, left=None, right=None, period=None) Here, x is an array_like x-coordinates to evaluate the interpolated values. xp are the x-coordinates of the data points and fp are the y-coordinates of the data points. The size of both should be equal.
