Scatter interpolation python
WebDec 6, 2024 · We can use the interpolation method from the scipy library. First, we create a function using the interp1d method by passing x and y values from the LOWESS output. Then, we use that newly created function to take new x values and generate y values for them. Note, in the below code, we used a couple of different options for interpolation. WebI'm plotting a 3D scatter plot reading my values from a file. Each line of this file has 3 coordinates and a standard deviation. Let's keep the errors aside for the moment. import os import numpy ...
