Comparing two rasters in scatter plot with different resolutions using ArcMap?

Question

I have 2 rasters taken from 2 cameras with different resolution over the same field. One shows NDVI values, the other is temperature. I need to make a scatter plot between these rasters but they have different cell sizes due to resolution of the camera and various number of rows/columns.

I tried Resample in Arcmap 10.5. to resize the smaller raster but it will not get the exact cell size and number of rows/col.

How can I compare 2 rasters with different resolutions if resampling function does not work?

To extract pixel values as table you can use arcpy. Adjust and execute in python window:

import arcpy
import numpy as np

in_raster = r'C:\GIS\data\someraster.jp2' #Change
out_table = r'C:\GIS\Default.gdb\rastertable' #Change

arr = arcpy.RasterToNumPyArray(in_raster) #Create array
structured_array = np.core.records.fromrecords(arr) #Convert to structured array which is required for NumPyArrayToTable
arcpy.da.NumPyArrayToTable(structured_array, out_table) #Create table
