Excel Chart Sample Size - excel

i have an excel file here someone else created which automatically changes the data size depending on the number entered into a cell. i cant for the life of me figure out how they have done it.. but i want to use something similar myself.
I will have a list from perhaps, A1 to A100, sometimes there are 50 entries, other times 20. So i want the chart to just show how many entries rather than flat lining the empty entries. (the empty data will automatically show 0).
This excel file i have, does that (see picture) but how can i do it also?

If the data in the column is a dynamic array, you can reference it with a spill range reference simply by A1#
Otherwise you can reference it by the formula A1:INDEX(A:A,MAX(NOT(ISBLANK(A:A))*ROW(A:A))). Note that this formula includes blank cells between the first and last non-empty cells.
Broken down, that formula is a reference from A1 to the last cell in the A:A column (INDEX(A:A,MAX(...*ROW(A:A))) that has a value in it: NOT(ISBLANK(A:A))

How to make an INDIRECT formula but with adjusting ranges

I'm hoping someone can help me make better use of the INDIRECT formula.
I have a list of sheet names in a table and an INDIRECT formula that uses that list to return a value in a specified cell - the list of sheet names is just an easier way for me to drag the formula down the table and read the appropriate cells without having to manually link each sheet.
=INDIRECT("'"&A2&"'!"&"K10")
This works fine for single cells as the range ref is simply stated as the text in the formula (K10), the problem arises when I need to start referring to a range such as K10:K15 and summing the values.
The range K10:K15 will inevitably have new rows added or deleted on the relative tab and as INDIRECT is using text as the reference it means the range doesn't automatically adjust - this is as I understand it one of the 'benefits' of INDIRECT but in this case is actually holding me back.
Also worth noting that the range (K10:K15) may move as rows are added/deleted above this, as this range is part of a larger table.
In simplistic terms I want to achieve the same result as a standard reference to a range on another sheet, e.g. =sum(sheet1!K10:K15) (as this will adjust when rows are added/deleted) but I just want to be able to dictate which sheet is referred to via a list I have in a table on a summary sheet.
How do I either write INDIRECT so the range adjusts when new rows are added/deleted or is there a different formula I should be using that achieves this?
Any advice greatly appreciated :)
=INDIRECT("'"&A2&"'!K"& MATCH(TRUE,INDIRECT("'"&A2&"'!K:K")<>"",0)&":K"&MAX((INDIRECT("'"&A2&"'!K:K")<>"")*(ROW(INDIRECT("'"&A2&"'!K:K")))))
This indirectly references the rows from the first non empty cell up to the last non empty cell in given sheet in column K. Not sure if you need to enter with ctrl + shift + enter (not in the app version).
Note: If the range contains empty cells in between the first and last non empty cell it will be included as value 0
Or in office 365 use the following:
=FILTER(INDIRECT("'"&A2&"'!K:K"),INDIRECT("'"&A2&"'!K:K")<>"")

Select all data in Excel by column name, omitting empty cells

The goal is to create a series of graphs that will update automatically based on the raw data.
So, I have created a graph manually and want to edit the formula to accomplish the auto update.
The column names will always be the same, so I want to be able to select all data in a column based on the name BUT ignore any cell that is blank (above zero maybe).
The formula excel has given me so far is
=SERIES(rawdata!$M$1:$M$6,rawdata!$A$2:$A$37,rawdata!$M$2:$M$37,1)
So, something like
=SERIES(rawdata![column name],rawdata![column name],rawdata![column name],1)
I'm not sure how the skipping blank columns should work either. To expand on this further only one of the columns can potentially contain blank values. So if a cell is blank in that column then that entire row shouldn't be plotted, if that makes sense!
strong text =OFFSET(Sheet1!$B$2,0,0,COUNTA(Sheet1!$B:$B) - 1)
Try this formula when you define the name for the column of values you would like to have data automatically added from. I know it works when each cell has either a formula or a value. Like a column that is automatically calculated based on values in other columns.
In this formula example the cell B2 refers to the first point of data in the column. (make sure your references are absolute! ie, use $B$2)
This automatically returns the range of data as it changes when CountA is added:
=OFFSET(reference, rows, cols, [height], [width])
=COUNTA(value1, [value2], ...)
Hope this helps! It worked for me! :) If you have completely blank cells in the column you might have to make a couple changes though.

Reference a variable value in another cell as part of formula

SHORT QUESTION
Ive got a formula =IF(ISBLANK(Q.1!C71),"",Q.1!C71) im trying to be able to set a control cell / variable so instead of C71 it would reference c*$B$1*, *$B$1* being my reference / control cell / variable in the same sheet as this formula, any ideas how to do this ?
LONG QUESTION
Ive got a spreadsheet that is regularly provided by a 3rd part with different data in it each time, although the column order of the data is always the same.
To get the data into my spreadsheet, i create another tab in the same workbook as their sheet and reference the data in their spreadsheet in a sheet i call import template sheet, i then from there copy and paste the import sheet into my spreadsheet, as all the columns match.
To reorder their columns in a non destructive way i use the following formula in my import template sheet, for instance if i wanted their column C, in my sheets column F i would place this in F1 and the pull the cell down so it does this for all rows :
=IF(ISBLANK(Q.1!C71),"",Q.1!C71) (the ifblank just helps sanitise the data by not throwing #ref if there is no data in the cell.)
The issue i have is that i have around 30 columns to re order and although the column structure is the same, there is sometimes some 'header' data (basically a text summary) at the top of the document of varying length, so instead of the first row i need being 71 sometimes it might be row 50 or row 90...
To speed things up id like to be able to have a control number / variable cell where i can set a variable for the starting row, and then reference that in my cell, so that i dont have the go and edit the formula in 30 different columns.
If you want to control the starting row of the reference by putting a number in cell B1, that would look something like this:
B1
71
Referencing Cell
=IF(ISBLANK(INDIRECT("Q.1!C"&B1),"",INDIRECT("Q.1!C"&B1))
INDIRECT allows you to build a string representation of a cell reference and then get the value of that cell. So we build a string reference using the value of B1, and then use INDIRECT to get the value of that string's referenced cell.

Efficiently update (growing) columns of data+formulas, w/ automatically updated rows of data

I have columns of data, each cell is a formula referencing data from several rows on another sheet (based on a dropdown box).
I now need to update many columns at once and simply copying the formula down into the next cell in the column, Excel tries to match the 'wrong' cells - the column is going down, the rows are going across, meaning I'd have to type in the correct cells manually every time I copy down this formula.
The rows are updated daily with pulled data/VBA and I can't touch the formatting of the columns either.
Not sure how to do this quickly. I have dates placed down each row/column, if that could be used somehow.
Shown: 2 different sheets, example of 2 rows a single cell will reference. There are many of these rows and columns. This is the formula:
=IF($B$7=1,'xx'!L619,IF($B$7=2,'xx'!M619,IF($B$7=3,'xx'!N619,IF($B$7=4,'xx'!Q619,IF($B$7=5,'xx'!Q619,0)))))
When copying the cells down, the formula updates L619, M619... with L620, M620... when instead I'd need P619, Q619...
This may help if you adapt it to your situation:
You can use the OFFSET or INDEX functions to set your spreadsheet up in such a way to transpose a horizontal row of data into a vertical column of data (and be able to drag the formula).
The trick is, you need a column (you can even hide it) with your increments in the cells i.e. 0,1,2,3,4,5,6,7...n
For example:
A1:A101 are where my increment values from 0 to 100 are.
my horizontal data starts at E15, and continues on with F15, G15, H15, etc.
This is my formula:
= OFFSET($E$15,0,$A1)
When I drag this down in a column, it corresponds exactly to the horizontal rows of data. The same thing can be done using INDEX.
Your situation sounds a little more complicated, but you might be able to build on this to suit your needs.

Keep absolute reference even when inserting rows in Excel 2007

I have a spreadsheet where I want cell formula to always look at a specific cell, even if rows or columns are inserted and the specific cell moves. Effectively, I always want to look at the 'top' cell of a table, even if new rows are inserted at the top of the table.
eg. Cell A2 has the formula[=$E$2]
Now I highlight row 1 and do Insert Row. The formula in A2 now says [=$E$3] but I want it to be looking at the new row 2.
The dollars will keep an absolute cell reference no matter what I do to the 'referencing' cell, but I want the cell reference to be absolute no matter what I do to the 'referenced' cell. If that makes sense!
Effectively, I have a 'table' in excel 2007 and I want to always reference the top row. The trouble is that rows are added to this table from the top so the top row keeps moving down to make room for a new top row.

Try =indirect("F2"). This will work if you know that the top-right cell of the table is always going to be $F$2.
You could also use the Offset Function:

or
https://support.office.com/en-us/article/offset-function-c8de19ae-dd79-4b9b-a14e-b4d906d11b66
Building on #ktdrv's answer (I can't comment): =indirect("F"&ROW()) would be $F2 if it's a reference that needs to be dragged down multiple rows. A minor drawback with =indirect() is that you lose cell reference highlighting for the formula.
