I am trying to write a code that will take column B and increment the values in the column by a value that can be entered into an input message box by the user. In the example provided below the user wants 0.1 as his or her increment for column B. Column A should be linearly interpolated as column B is shortened.
So far my code is just set up to grab data from the specified machine and bring it into the sheet where the raw data will be cleaned into usable data. I’ve been researching for days and can’t quite get my head around how to set the increment and interpolate the data.

Raw data looks similar to this but much larger. There is a lot of data missing here. One of the files has nearly 13000 rows. A completely parsed file will have less than 400 rows.

Return population for a City
If you have a list of cities in A2:A100, use Data, Geography. Then =A2.Population and copy down.
Lots of views and no replies. Is this because my question is too complex or because no one understands what I'm asking?

i won't say i don't understand what you are asking, just that i am confused by your examples and i can not see any logic to what you ask and what you show

i see that you are creating a list in column that increments by a value of 0.1 but where do we get the 0.527421817 from and how does the maths work to make this 0.991580884 in the next

maybe a little more explanation one example at a time and telling us your logic in plain words rather on relying on the examples (which mean something to you but not me, but may upon further detail)

Thx for the reply, AKA Trouble. I’ll try to explain it better.

I have a series of two columns that will contain a lot of raw data. Column B is the controlling column. The values in column A is directly connected to the values in column B.

The first part of my goal is to increment column B by a number specified by the user. I would assume that input needs to come from a message box. After the user has entered their desired increment value, column B is then modified or the new array is copied to another location. This will be my x axis for my graph. I need it to be the same increment every time I run this macro for a different set of data. This value needs to be in nice round numbers.

The second part of my goal is to interpolate the values in column A as the size of column C is decreased.

To interpolate properly the macro needs to search col B for the numbers immediately smaller and larger than the newer, nicer column B value located in column E.

Interpolation eqn: y = y1+(x+x1)*((y2-y1) / (x2-x1))

Where:
y = newly interpolated column B value
y1 = column B value that corresponds to the column A value just less than the newly created column E value.
y2 = column B value that corresponds to the column A value just more than the newly created column E value.
x = column E à revised column B value
x1 = column B value just less than new column E value
x2 = column B value just more than new column E value

Ex. In raw form, column B is incremented by a very small amount (approx. 0.002). I would like to call a message box asking the user to enter an increment value. If the user enters 0.01 as the new increment, then the new values for column B will be:

I hope this clears things up a bit. I'm still trying to figure the code out, but getting nowhere. Thanks for your help on this one, everyone.
