Is There Any Quick Way (pc Program) To Calculate Slope Of Curve? - Excel |
|
Ok I have a problem in that i have about 58 batches of data and have a
plot of a curve for each batch. I need to calculate the slope of the
steepest part of each curve and am restricted for time! Does anyone
know of a quick way to do this without printing off each graph and
calcalating tangents! Currently my data is in excel however I could
put transer it to MATLAB or download another program you can
recommend???
Also what technique do you recommend to use to fit a curve of best fit
to the data??????
Thank you

Cell B5: start time: 4:15 formatted as 4:15:00 am
Cell B6: finish time: 6:15 formatted as 6:15:00 am
Cell B7: total time: 2:00 formula in cell: =TEXT(B6-B5,"h:mm")
Cell B8: total batches processed: 22 (this is entered manually)
Cell B9: batches per hour: formula in cell: =B8/TEXT(B7,"h")
as long as I have this formula in cell B9 the answer comes out correct which should be 11 per hour.
If the formula in B9 is B8/B7, the answer is 264.0, Is this because of the way excel is reading the total time or the total time is formatted as a time, not an actual number? Is this the correct way to solve the problem?
answer should be 11 per hour.
Received Date & Time: 10/29/2010 3:27:00 PM
Completed Date & Time: 11/1/2010 3:57:32 AM
Business Hours: 08:00 AM to 05:00 PM
Non Business hours: 05:00 PM to 08:00 AM
Weekdays : Monday to Friday
Weekends: Saturday & Sunday
If I calculate TAT for this time period it should show me 1 hour 33 minutes, why because business hours are closing by 5:00 PM on 10/29 so it should not calculate duration after 5:00 PM to until 08:00 AM on next day, however 10/29 is Friday so formula should calculate the duration from 10/29 Friday 3:37 PM to 10/29 5:00 PM and again it should calculate from 8:00 AM on 11/01 Monday and formula should skip Saturday & Sunday.
In this scenario I have completed the task before 8:00 AM on 11/01 so it should show duration of 1hour 33 minutes.

I am trying to calculate our On Time Delivery. I want this as a simple percentage of jobs. I have got this running in the following way:
Column M - Estimated Delivery dates
Column N - Actual Delivery dates
Column O - =IF(SUM(M2-N2)>0,1,0)
Then I have calculated On Time Delivery as: =SUM((SUM(O2:O252))/(COUNTA(N2:N252)))
This seems to work fine. My problem is, if we enter a date in Estimated without a corresponding Actual date, the formula for Column O fills out anyway and improves our On Time Delivery Percentage. How can I set this up so that the formula doesn't calculate if there is no data in Column N?
Any help much appreciated
Thanks,

I have two columns of data: column A contains the date and time in the form dd/mm/yyyy. Column B contains a number value. All the times are in order, so column A looks like:
01/01/2007
02/01/2007
03/01/2007
I have data from 2007 to 2010. I need to calculate an average daily value (in column B) for each month, and display it in column C. So, for January, I need to calculate the average of 31 days, February, 28 days, etc.
Is there a function I can use to do this? I've been trying the AVERAGEIF formula but can't get it to work. Any ideas would be much appreciated!
Many thanks,
Caitlin
triangle. I copied it to create a new data set and used find &
replace to change the worksheet references to the new ones.
The cells still contain the result of the old formula referring to the
previous worksheets. The only way I can get the formula to return the
correct result is to edit (F2) each cell and press enter. Calc now
(F9) does nothing.
I've seen this before, but this time, I need to calculate many
thousands of cells and don't have time for this workaround.
Any ideas?
Thanks.

Can you please help me,
A1= time in
B1= time out
C1= time in
D1= time out
I want to calculate the late and under time,
Office start at 9:am w/30 mins Grace period,
The break time is one hour only, please include over breaktime in calculation.
End of office hours 6:00 pm, strickly no over time
difference where the times cross midnight. Example:
Start time: 23:50:00
End time: 00:15:00
How would you formulate an equation to determine the duration of time or
differnce between the start and end time?
The cell turns blue and then wherever I move, it highlights those to.
No matter where I go on the page. If I Alt-Tab and work in another
program on my computer, that excel page keeps highlighting wherever
I move even in those other programs (I know this sounds confusing).
When I return to excel thousands and thousands of cells are blue.
The biggest problem is that the highlighting won't turn off, no matter
what. I can't select anything from the tool bars, do any work on the sheet or close the program.
I can close it only with the task manager but when I open it again,
the cursor is still stuck in the highlighting mode and won't perform any
other functions.
Do you think this is a problem with my computer, the excel program? I have changed my mouse and this didn't help.
Is there some shortcut to turn off this highlight feature other than restarting
my computer. Which is the only current way I can get rid of it.
Thanks for any advice,

I'm really hoping someone can help me with this...
I need to plot percentages over time in a line graph in excel. I don't want to have to do a percentage equation in the spreadsheet, I just want excel to take two sets of values and display the percentage in the chart. For example, I need B1 as a percentage of B2 for week 1, C1 as a percentage of C2 for week 2, etc....
Can someone please offer a suggestion for how to do this? I would really appreciate it.
Also, would it be possible to link data from other sheets in the workbook into one single chart?
I want to calculate the total time worked such that i have the hours worked. So if i worked 7 hours and 30min then the total time would be 7.5hrs. But i am not sure how to take into account the lunch break time (see enclosed sheet).
anyone have any ideas?
I am using
ActiveSheet.ShowAllData
in a piece of VBA and it causes an error if the sheet does not have a filter applied! Is there an if statement I can use to check if the data is filtered?
Thanks - this site is an absolute life saver!
