digitize | A R package to extract data from scatterplots

Ok so my goal is to convert from string "1234567" to char array what I managed to achive(incredible) but now I am stuck and have no idea what I did wrong here...

I have a large set of coordinates from the critical and endangered habit federal registry. I'm trying to digitize these maps for analysis. Here's a sample of the data as an example.

I am struggling to extract the curve from this image:

It represents scientific data which I don't want to touch, to avoid introducing errors, so I cannot just manually redraw the line in a plot digitizer: I want to automatically extract the curve, which then I will feed into a plot digitizer.

I tried programmatically drawing a white grid over the image, trying to exactly overlap the grid and delete it; but unfortunately this is the scanning of a paper sheet, so the grid is not perfect, hence spacing between lines is not always the same.

Code used for grid:

I wanted a python alternative to discretize2d in R. An alternative I found over stackoverflow was to use pandas.crosstab and pandas.cut as so,

Suppose I have a series of 2d coordinates (x, y), each corresponding to a weight. After I arrange them into bins (i.e. a little square area), I want to find the sum of the weights that fall into each bin. I used np.digitize to find which bins my data falls into, then I added weights in each bin using a loop. My code is like this:

So I'm trying to make function for preprocessing dataaset in semantic segmentation. but it tells me that my function is not define. Whereas is actually define on there. my code is like this

I have a DataFrame (df_value_bin) with Multiindex which is the binned values, like this:

I have a continuous input function which I would like to discretize into lets say 5-10 discrete bins between 1 and 0. Right now I am using np.digitize and rescale the output bins to 0-1. Now the problem is that sometime datasets (blue line) yield results like this:

I tried pushing up the number of discretization bins but I ended up keeping the same noise and getting just more increments. As an example where the algorithm worked with the same settings but another dataset:

this is the code I used there NumOfDisc = number of bins

I want to get an Array with the reversed number when I invoke the method (Given a random non-negative number, you have to return the digits of this number within an array in reverse order.) I initalised a scanner, but whenever I execute, I only get the address in the heap I suppose (for example: [I@66a29884). I know this problem also occurs when we have String, which why we have the toString-Method. Is there a way I can print the array or the reversed numbers out in the console?
