Ignoring Data Points For Regression Lines

I want to add data points to the scatter plot that are not part of the data
ie. add points to find their concentration on a standard curve.

Does anyone know if there is a customer format I can use to change the percent value of a cell to basis points? I tried creating my own, but was having difficulty. For example, if the cell value in A1 is 2%, I would like to have it say 200 basis points instead.

Thanks.

So I've got some data, which has the approximate form of a sine function. I want to find all the x-axis intercepts. I tried using the intercept function and swapping around the y values for the x values, but it only returns 1 value (so I'd guess it uses a linear regression to estimate a single line through the axis).

I was thinking of trying a nested if/and statement but I haven't quite figured out how to do it. Basically I want to identify the two values where it switches from positive to negative and also indentify the values where it goes negative to positive, I can then fit a straight line between them to find a better approximation of the intercept (though it might not be necessary). Preferably I'd like it all one function as I'm not doing it in VBA (I might do later though, we'll see).

Can anyone suggest how I'd find these value or the x-intercept. Any help would be greatly appreciated.

I have a graph with various information in it. One is a line graph that tracks hours used in that department per month. The problem is that when it gets to the last month, and there is not yet data for future months, the line goes down to Zero (leavin this big diagonal line that makes the data look funny). I need this line to stop on the last month there is data for. (I do not manually enter the data, it is a formula that I do not wish to delete.) I know I can manually move the data that the line is pulling to make it stop on the last month, but I have a graph for 36 different departments and that's a pain to have to manually adjust 36 graphs each month. Is there a way to tell the line to stop if there is no data? Thanks!!

I'm trying to write a formula that will automatically take a group of football (soccer) scores, compare them with a set of predictions, and then allocate points according to how close the predictions are to the actual scores.

E.g.
Manchester United 3 - 0 Arsenal
Prediction: 4 - 1
Points: 1

I've found a formula online that works for most scores; the correct score (e.g. 3 - 0), a correct win (e.g. 4 - 1), and in the case of a draw (e.g Man Utd 1 - 1 Arsenal, and the prediction 2 -2), correct draw (but not the correct score). The points are as follows: Correct draw (Prediction = result): 4 Correct win (Prediction = result): 3 Correct win, incorrect score (Winner correct, score not): 1 Correct draw, incorrect sco 1

The formula I found online for all but the correct draw is: =IF(A3&B3=C3&D3),3,IF(AND(A3=B3,C3=D3),1,IF(AND(A3>B3,C3>D3),1,IF(AND(A3<B3,C3<D3),1,0)))))

Could someone help me work out how I can write a formula to add before the above that will check the contents of four cells (the home score, away score, home prediction, away prediction), and if the number in all 4 cells are the same, allocate 4 points? I've tried using averages, but some combinations would void this. I've also used the SUM function, but the same happens, as with MULTIPLYING.

Something like =IF(A3:D3) are equal, 4,0

Below are a few examples of what I mean:
(Result) (Prediction) (Points)
A B C D E
3 - 3 3 - 3 4
2 - 1 3 - 1 1
1 - 0 1 - 0 3
3 - 3 2 - 2 1

Apologies in advance if I haven't explained this clearly enough.

Thanks

Will
