Graph Bell Curve Chart
Jul 14, 2014I'm trying to graph a bell curve chart using the following data
Hotels per state
Total
AK
4
NH
5
[Code] ......
As you can see I have states and the number of hotels per state what I need not for statistical purposes but more for "pretyness" is to sort this data in a way that what you get is a somewhat of a bell shape curve graph.

Jun 5, 2014I have a data set (Set#1) that consists of a positional rank (1-240) and a dollar value ($46-$1) for each positional rank. It's not a straight line set.
DataSet.JPG
What I need to do is take that curve and apply it to another data set (Set#2) (1-240) and assign a dollar value ($46-$1) to each positional rank.
A "corner cutting" way of doing it would be an Index/Match to simply carry over the dollar value from (for example) #45 from my Set#1 to #45 in my Set#2. This could work reasonably well with data sets of the same size, but mine aren't always the same size, so I need to apply the curve itself. I
Pivot Chart Object: Find Any Suitable Object To Choose From To Make A Pivot Chart In Powerpoint
Mar 21, 20071) i have office 2003 on a laptop. within powerpoint, i can create a 'microsoft excel chart 11' object. to create a link to the excel data source, do i have to go through the odbc sql setup? it works, but i don't want my powerpoint to be dependent on some excel file somewhere. what are the other options to insert/make a functional pivot chart in powerpoint with the data also within powerpoint? the data as sheet option does not result in the chart being a pivot, it's just a plain chart. it has to be a proper object, not an image paste or a chart that updates links with the excel file open.
2) i have office 2007 on my other laptop. i can not find any suitable object to choose from to make a pivot chart in powerpoint. what's the best way to go about in 2007 version?
3) am i going about this the wrong way with the objects? should i be after vba code?

Jan 28, 2009I'd like to apply a curve to a column of student exam grades and have the curved grades displayed in the adjacent column. Here is how I'd like to curve:
I like to make a linear function out of two coordinate pairs.
First Pair (x1,y1) = (Highest Exam Grade, 99) = (H,99)
Second Pair (x2,y2) = (Class Exam Average, Desired Exam Average) =(C,D)
Slope = (99-D)/(H-C) = m
Linear Function = Y-y = m(X-x) = Y-99=m(X-H)
Each student grade would = "Y" i.e. Y=m(X-H)+99
Create Growth Curve
Aug 28, 2007Does anyone know of a statistical formula that would create a normal growth curve?
For example. Let's assume that I want to forcast growth from January through December. I know that in January I will have 100 units. In December, I will have 1,000 units. Is there a formula to predict the the units in Feb-Nov (using a normal growth curve)?
Calculate Best Fit Equation Of Curve
May 16, 2008I am trying to calculate the equation of a curve which best fits some data. On the x-axis is date and y-axis the readings. The curve is quadratic, so on the chart I am fitting a 2nd order polyomial and displaying the equation. To prove that the equation the trendline gives me is reasonable, I am applying the equation on the x parameter to get the y parameter estimate and looking to see the error between predicted and actual - see attached.
The equation and the output from it are clearly rubbish, even though on the graph the trendline is a reasonable fit - see attached. Has anyone any ideas why? I think it has something to do with using a date on the x-axis but no idea why. Is there a way to correct for this? I also tried using the following I to calculate the coefficients which came up with a reasonable forecast (although linest should only be used for linear data): =LINEST(C3:C15,B3:B15^{1,2,3})
Create S Curve Based On Dates
Apr 4, 2014I am working on Project Planning, I need to create the Progress curve for our Project based on Weight Factor every month.
I need to create the Plan and actual curve based on the dates defined in particular activities. Once the activity progress is calculated every month based on cut off date then it will sum product with corresponding WF to get the progress achieved every month. Presently I am calculating the values every month and pasting the values in Chart data every month. I had created the S Curve and attached here.
Now my objective is to automatically calculate the values for the entire cut off date at one time (From Project Start to End). i.e I don't want to do any manual work in the Chart. I will update only the actual Dates in the file, then the curves need to get automatically updated.
1) I don't want to calculate the progress for individual activities, I would like to calculate the overall progress directly.
2) When I change the Cut off date, then the previous values needs to become static.
Formula To Distribute A Value Along A Bell Curve.
Nov 19, 2008I'm trying to find a formula that would spread out a value amongst multiple cells along a bell curve. Say I have $x,xxx. I want to spread that amount out in a certain proportion, regardless of how many cells I'm spreading it throughout.
Say I have a $10,000 project. I want to be able to spread it out like a bell curve in the cells I choose. For instance, if it was a five month project it would be distributed as
January - $1,000
February - $2,500
March - $3,000
April - $2,500
May - $1,000
If I added another month it would change to
January - $833.33
February - $1,666.66
March - $2,500.00
April - $2,500.00
May - $1,666.66
June - $833.33
I already thought of manually adding percentages to each cell, but the formula needs to be dynamic.

View 5 Replies View RelatedCreating Curve With Multiple Values Already In Excel Spreadsheet?
Jul 11, 2013Here's the spreadsheet I am talking about : [URL]
So as you can see each row = one day divided in 2 cycles of 12 hours : every 12 hours the cat gets a new injection of insulin (the columns "U" being the number of units of insulin the cat receives)
Now I want to turn this sheet into two different curves that would look like these : [URL]
As you can see the first graph shows data based on days (x) and insulin dose (y), while the second curves shows data based on days (x), and blood glucose values (y). This is basically the only way we could clearly see how the cat's disease is evolving over a long period of time.
If he had just started to take all these values from his cat I guess it would be simple to do, but since he already has a lot of data entered in his spreadsheet, I was wondering if I could use this data (and not write each number in a new document), to make things a little more simple and to avoid mistakes.

View 9 Replies View RelatedDynamic Chart That Moves Up And Down To Find Data
May 6, 2014I know how to make a dynamic chart that shows only the last X number of rows. However, I'm looking to do something slightly different.
I have columns A and B both with 3000 rows of values. I would like to make a bar graph. Some of the rows are NA(), some have the data that I would like to graph. The data I would like to graph is always in a group, say from rows 100 - 200, but this could change in location from rows 95 - 195 instead, and could also change in number of rows to be rows 95 - 150 (ie. 55 rows rather than 100 rows). I would like my bar graph to be able to search Columns A and B and pick out the section with data (ie. not NA()) and graph it. I had introduced the NA() hoping that I could just put the entire range in the chart and it would pick out the numbers, but I gather this only works when using a scatter graph which just won't work for my needs.
Excel 2007 :: Find And Format Text Within Chart Textbox Object?
Nov 15, 2012I have a text box within a chart tab which is populated with text values from a worksheet within the workbook. That part works fine however i want to be able to achieve the following example:
Current Text: Component Name - Notes
if there are notes against the component name i want the name to remain in black and the notes to change to blue
Aim: Component Name - Notes
If there arn't any notes then for the component name and the "-" to change to a light shade of grey
Aim: Component Name -
There are 26 components, each on their own lines in the textbox so im thinking either a loop where the cell reference is variable eg. ("CY" & i) or using the .find with a variable.
My code so far is:
Code:
Sub Chart_Notes_NTCA()
Dim i As Long, j As Long, Counted As Long, Total As Long
Dim Ans As String, Notes As String
Dim Cht As Chart
[Code].....
