How to build a simple graph from 2 columns of a table, but with complexity?

Question

excel

you need to build a simple income-loss graph based on a table of two columns - dates and amounts. The question is how to make such a graph so that you can subtract any amount from a column with amounts, but the graph does not change. That is, so that the addition of the amount is taken into account on the chart, and the subtraction of the amount is not taken into account.

Answer 1

Two columns are not enough.
We have:

1. the date,
   
2. sum.
   

Need more columns for:

1. subtracted number,
   
2. values ​​after subtraction,
   
3. term of the number,
   
4. column after addition.
   

The graph is built on the basis of the first and additional fourth columns.
