1. I use a number of x,y pairs
2. From x,y pairs I produce "scatter" type chart
3. From the chart I get trend line and its equation e.g. 5-order polinominal
4. I convert equation into excel formula
5. I apply formula onto the same range of x argument and produce graph
6. The graph is very much different from the trend line!!! I would expect exact match as I use equation/formula for the trend line.
I have a simple x y scatter graph, to which i have a trend line running through it, fine.
what i need to do is fine some values according to that trend line. e.g. my X axis goes up to 60 and my Y axis goes to 10, so if i draw accross at 55 from the trend line, i then go down to a number on my Y axis.
On top of these graphs, i draw a line (insert a line shape) corresponding to a certain gradient in the data presented. I do not want this line to be exact (i.e. not point to point) as it is best to be drawn by eye so that the general 'gist' of the data can be found. What i would like, using any method available, is to be able to find the gradient of this line i have just drawn which obviosuly must be done taking into account the scale of the graph. The scales of the graph will not be consistent across all applications.

View 7 Replies View RelatedIs there a way to get an equation for a trend line and have excel automatically export the equation to a cell where it can be used. The only way i currently know how to do this is to manually type the equation.
View 8 Replies View RelatedI currently have in my equation the trend function to linear extrapolate the date a line would cross either my upper or lower limits (100.1 and 19.9) between 2 data points. However if the 2 data points span both the upper and lower limits (as per the 2 attached examples) then unfortunately the trend function is only able to return the 1 date (where I've specified the x value). Is there any way for the TREND function to trend the 2 values? Do I simply add the 2nd x value to the new x's?

i need to have a bar chart with trend line individually on each data items e.g.Sales, Availability% etc. when i tried to use trend line it prompts me to enter series i.e Ending_Date and it draws trend line for only that period comparing all data values. is there any way to have individual graph for Sales, Availability%, Waste%, Number of Stores with trend line covering
Ok so heres an example workbook:
Book5.xlsx
As you can see from the workbook, each column's amount of numbers depends on the data pulled from an index/match function.
These numbers will change and I want the TREND function to dynamically change with the data.

View 6 Replies View RelatedI'm trying to create a formula where I can show the trend of two values from one month to the next that shows wheather the results went up or down in a positive or negetive value. For example:
If I have a transfer % of 18% in October and November MTD is at 17% - the arrow would then reflect downward showing in green, as the lower percentage is better. but I need the arrow to show upward in Red if say the value for November MTD was 19% instead.
I tried conditional formatting and attempted an "If" formula. I must not have all the information to create the formula as it errors out on me. I can create it if only looking to reflect one arrow...

I am having trouble copying a charts trend formula into a cell.
the best I can do is select it as follows:

I have a worksheet that I need to be able to easily copy and paste the formula/formatting from the row above, but not the Values entered, (if any). I am using columns A to DG.
I just really need to be able to copy all the formula in these cells down - nothing exciting or fancy.
I've tried formatting as a table as per some searches and that was difficult! My column headings changed, and when I inserted a row, two of the formula's wouldn't copy down - plus the shading and borders went wonky in places.
I have two columns where TREND does not work well. I want to calculate the TREND value of Column 2 (PERCENTILE RANK) based on a new RAW number. If I TREND between just the two rows, the value is fine (i.e. If I TREND between 105 and 110 RAW, I get the right PERCENTILE RANK if the new X value is 106 (which is 15.3% PERCENTILE RANK). How can I make a formula that will only look at the two rows and TREND just those two rows to give me the right PERCENTILE RANK.
RAW PERCENTILE RANK

View 8 Replies View RelatedI'm trying to figure out how to do seasonal forecasting based on volumes. I tried to use FORECAST but the numbers are not accurate.
I have actual data to work with to come up with my forecasting on a monthly basis. Our yearly calender is from Nov 08 to Oct 09.
Here's a sample of the data....
What I have is a column (column A) that only has two data entries at any one time.
I need column B to fill in the trend of those two data points.
My problem is I don't know how to deal with the cells that say #N/A. Which is every cell other than the two cells with data.
If I replace the #N/As with say 1, then it messes up the trend data points.
It seems like I need to be using the trend command, but any solution would be welcome.
When using the Trend function, I can get the value for individual future periods. I then can get a total for the year by summing each individual future period.
What I don't know how to do is sum them all using one formula. For instance, If I know the values of periods 1-5, how would I write a formula that would sum the future values (in one cell) of periods 6-12 -- without having to sum each future period individually?
I am trying to use VBA to find a value on a trendline. I have been unable to call the TREND function from Excel, and I can't see what I'm doing wrong. I'm using the following line of
point25 = WorksheetFunction.TREND( Range("d2:d25"), Range("c2:c25"), 25)
I keep getting "Runtime error 1004 - Unable to get the Trend property of the WorksheetFunction class".
I need to analyse trends between a range of cells. The idea is to display an image of a triangle pointing up if the percentage between the current month and the previous is bigger, a triangle pointing down if the percentage has decreased or a rectangle if both months are the same. I've tried to build a userform to ask the user to input the range and then analyze the data...with no luck at all.
View 9 Replies View RelatedI am using the Forecast formula to give me a value from a Linear trend. However I need to limit the resulting value that is displayed within a min and max value. Background: This is to allow me to calculate the amount of bonus someone will earn depending on the Percentages of their target they achieve. The min bonus is 25% when 80% of target is achieved and max bonus is 100% when 125% or greater of target is achieved.
So the Forecast formular works great using the existing values, but i need help limiting the results to between 25% and 100%. I was trying to use a sumif formula to copy the resulting cell but only if the value fell between the 25 and 100%. I've attached the spreadsheet as I think it will highlight what i'm trying to do better than I can explain it.
I am trying to use the TREND worksheet function on a vba array. I keep getting Runtime error 1004: Unable to get the TREND property of the WorksheetFunction Class. I can bypass the error (like it were a search with no result), but I get no result of any kind from the function. My search of other threads yields nothing concrete, but causes a guess that it may have to be used on a worksheet range not a vba array. But that's not actually stated in any of the threads, and I find no documentation to that effect. Is this the issue or is it something else altogether?

Ive got an inventory of about 2000+ items as well as items that can be broken down into more specific groups such as colors, designs and sizes. What i want to know is how to get the correlation, thats excel function CORREL(), of each item for the time weve had it. The data I can provide is the monthly quanitity sold of the item.
For example I have item A.
Sold Month
5 1
7 2
4 3
5 4
and so on. Easy enough to do. My only problem is I would have to manually do that 2000+ times for my entire inventory to figure that out. What I wants is a command that can verify my item code, which is simple enough as I can convert the item code to something as simple as a string or leave it as is. Not every item has been in the system an equally long time though. If that were the case i could just copy it with blank cells to fill the space and copy and paste all the way down. So I need to find a way to get an IF statement to correlate the corresponding cells IF the item number matches the target cell. What I have right now is something to this extent.
=IF('2'!$A:$A,A1,CORREL('2'!$B:$B,'2'!$E:$E))

View 3 Replies View RelatedI have a problem with an array formula. The file is attached for better comprehension.
I've built a multi-criteria lookup based on INDEX and MATCH.
The idea is in Sheet 1, in column F to put 1 (one) if each record of columns A,B,C and D (all combined) match any record in Sheet DATA. If not then 0 (zero).
The array formula works nice for each of the records. However, I get a ZERO in Zinc! If you check DATA, you can see that Zinc is there, from line 221 to 224!
I can't understand why this happens since i've pasted the formula for each of the lines in column F.
I have odds line numbers on this excel sheet which is the VL column. I'd like to be able to scratch a horse, (delete a horse from the sheet) and the odds line (VL column) will update to the new value after the horses is scratched from this sheet.
Now I do this in a program that uses VBA and transports this info to Access, where then I export to Excel to this sheet.
Here's the formula I use for the odds line...
#EQUAL(#COLVAL(51),1, .00001)*((#COLVAL(53))-(#COLVAL(53)*.4))/(#COLVAL(50))+
#EQUAL(#COLVAL(51),2, .00001)*((#COLVAL(53))-(#COLVAL(53)*.25))/(#COLVAL(50))+
#EQUAL(#COLVAL(51),3, .00001)*((#COLVAL(53))-(#COLVAL(53)*.10))/(#COLVAL(50))+
#EQUAL(#COLVAL(51),4, .00001)*((#COLVAL(53))+(#COLVAL(53)*.05))/(#COLVAL(50))+
#EQUAL(#COLVAL(51),5, .00001)*((#COLVAL(53))+(#COLVAL(53)*.10))/(#COLVAL(50))+
#EQUAL(#COLVAL(51),6, .00001)*((#COLVAL(53))+(#COLVAL(53)*.25))/(#COLVAL(50))+

#EQUAL(#COLVAL(51),9, .00001)*((#COLVAL(53))+(#COLVAL(53)*1.3))/(#COLVAL(50))+
#EQUAL(#COLVAL(51),10, .00001)*((#COLVAL(53))+(#COLVAL(53)*1.6))/(#COLVAL(50))+
#EQUAL(#COLVAL(51),11, .00001)*((#COLVAL(53))+(#COLVAL(53)*1.9))/(#COLVAL(50))+
#EQUAL(#COLVAL(51),12, .00001)*((#COLVAL(53))+(#COLVAL(53)*2.2))/(#COLVAL(50))+
#EQUAL(#COLVAL(51),13, .00001)*((#COLVAL(53))+(#COLVAL(53)*2.7))/(#COLVAL(50))
I added a couple of columns in the excel sheet to occomadate this formula which should work if coded into excel properly. Notice the (50), (51), (53) numbers.
(50) = TC in this excel sheet
(51) = 2V in this excel sheet
(53) = TCa in this excel sheet
VL column is where this formula updates to.
I have one other minor problem with something else, but so not to confuse, I'll mention it later.
