"Chart A and B have entries in the vertical direction" What does this mean? What type of charts are they?

Charts are just a graphical depiction of data. They do not contain data. If you want to access the data that is used to make a chart then you will need to have code read that part of a worksheet, not the chart.

"I need to compare in the calculation sheet in a 2 x 2 matrix" What is "the calculation worksheet"? What kind of comparison do you want to do? What are each of the four elements in the matrix? "after each 2 x 2 matrix is solved" What do you mean by "solved"? Are you trying to solve simultaneous equations for a variable?

The description here is not specific enough to give you any actual code to do what you want. I suggest you provide an Excel file with an example of what you are describing, and a mock-up of what you want the result to look like.
