Scatter Graphs And Horizontal Line Intercepts |
Scatter Graphs And Horizontal Line Intercepts - Excel |
|
Dear All,
I am attempting to find where a horizontal line drawn across an X by Y graph intercepts the curve.
I am plotting temperature on the x axis against speed on the y axis. The results form a curve from zero to maximum, and back to zero as temperature increases.
I have an optimal rate which I would like to determine the temperature breadth of. This involves drawing a line across the function curve and determining the temperature at which it intercepts the performance curve (against the x axis "temperature").
Can anyone help? I hope my description is adequate!
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 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.

Hi there. I know it sound like a really simple thing but its really stumped me.
Instead of the y axis being on the left hand side, i wish for it to cut at 0,0. I have positive and negative values and I need it to be in the centre instead of on the left.
I have tried formatting both the axis and it would appear that the x axis already cuts the y axis in the right posistion so i need to format the x axis to make the y axis cut it at 0,0. I have already tried typing in 0 instead of 1 and it keeps saying it need to be number more than or equal to 1.
Any help would be greatly appreciated.

This may be less of an Excel question than a general data display question, but I'll try here.
I have 3 variables that I'm charting. I have one on the primary axis and it's values are in the billions. I have one on the secondary axis and it's a percentage. I need to display a 3rd who's value is in the millions. If I put it on the primary axis, you cannot see modest changes.
Is there a tricky way to get all three on one graph? I know I could split on two graphs, so that's my backup plan.
Thanks,
Dave

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!!
Morning all,
Say I had a line graph for 4 years and I wanted it to be a solid line for the first three and a dashed line for the last one, is that possible?
Many thanks for your help

Hey everyone,
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 am puzzled by a thin black line (that looks like a border line) on a spreadsheet that I am unable to remove, whatever I do. It starts halfway across column B and stops just at the end of column Z.
It is not a border line.
It is not a page break.
If I delete the rows it appears on it remains visible.
It is not an object floating on top of the spreadsheet.
Any ideas?
Thanks.

I am using the code below to disable the save function very successafully. However, is there a work around to allow a macro to save?
----------------------------------------------------------------------
Private Sub Workbook_BeforeSave(ByVal SaveAsUI As Boolean, Cancel As Boolean)
'this disables the save function on the XLS
MsgBox "****Save is Disabled****"
' Following line will prevent all saving
Cancel = True
' Following line will prevent the Save As Dialog box from showing
If SaveAsUI Then SaveAsUI = False
End Sub

I have a userform containing a multicolumn listbox (ListBox1) and textbox (txtSelectedJobNumber).
When a user clicks on a line in the listbox I want to automatically copy the text in the 3rd column of the selected line to the textbox.
If anyone could provide code which would allow me to do this I would be grateful
Thanks
Colin

Hi Excel experts,
I am working on a worksheet, and would like to have an entire row transferred to another worksheet based upon a certain cell's value.
Having searched through the many solved threads on this site, I attempted to customize some of the code to my worksheet. Not being proficient in Macro/VBA, I failed. I figured I would ask for help, and see if anyone can provide what I am looking for.
Basically, I am attempting to construct a "work in process" file, and would like all completed work to be deleted from the work in process sheet, and transferred to a sheet that contains a running list of all work completed.
Attached is an example of what I am working on. I would like Column Q (Status) to determine if a row can be moved to a sheet that contains the list of all work completed, and eliminated from the original sheet. Once Status is updated to "Complete", it would be helpful to be able to run a macro/click a button that would perform the transfer.
Can anyone assist?
Thanks!

Hi all -
Im very familiar with how to write a macro to automatically autofilter a list based upon a Cell Value (i.e. Range =(A1)...etc.).... but what I cannot figure out how to correctly write is a way to have Excel automatically autofilter a list for any row that CONTAINS the Cell Value, instead of just the exact value.
Cell Value = "birds"
Example -- I need to filter every row so that I see every row that CONTAINS "birds" in the character-string, not just the row that = "birds".
a) is this possible?
If not, I'd like to know also so I can stop attempting to guess (-;
Thanks!!!

I'm looking for a formula that pulls the text from a cell unti it hits a space.
I'm using the formula below but keep getting #VALUE results
B1: =LEFT(A1,FIND(",",A1,1))
I know it's not that hard but can't figure it out.
thanks for the help

Is there an Excel guru that can help with this - its related to "drop down menus"
I have 2 colombs of data.
AT the bottom of the first, I have created a drop down menu using the "data validation" feature in excel.
At the bottom of the second colomb, I have used an "IF" function that returns a result, which depends on what value is chosen from the drop down menu in colomb 1
The problem I have is that I want the TRUE result from the IF function to be another drop down menu, being the data in colomb 2.
How do you write an IF function where the TRUE result is a drop down menu??
I tried to create a drop down menu of colomb2 elsewhere in the spread sheet, and used that cells location as the TRUE value, but this didn't work either...
ANy suggestions??

I have cells in a column, some colored yellow, some not. I am trying to use
the SUMIF function to sum only the cells in the range that are colored. Can
this be done? Can I enter something in the "criteria" part of the formula
that can do this?
=SUMIF(D3:D13,"criteria",D3:D13)
I also tried to use the CELL function's color feature, but I couldn't get it
to work right. I don't know how to get Excel to recognize if a cell is
colored in a formula.
=CELL("color",cell)
It might just be that I don't know what this means in Help:
"color" --> 1 if the cell is formatted in color for negative values;
otherwise returns 0 (zero).
Can anyone help?

I have the code which filters my spreadsheet and copies that dataset but I think I need to add an IF that skips the copy line when the criteria is not met. Any ideas?

Hello
I'm quite experienced Excel user. I've never come across this problem but tinkering in every conceivable way within Excel settings and the solution has eluded me.
I have added a worksheet created elsewhere (it is a form I need printing, with the data coming from 2 sheets I have created from scratch) which has pre formatted cells for Date and Client Name etc.
When I try to reference the cell in this added sheet from my 2 sheets, instead of the result, it always displays the formula, not the result.
I have tried doing it from one of my sheets to reference to this new, and that displays the result and not formula. I can't imagine why it's doing this and I've never seen it happen before.
Formatting cells, giving cells names rather than the usually adequate of reference to the Cell Number doesn't change things. I wonder if I've picked up some legacy protection from the original form but can't see anywhere in the tools etc that's obvious.
There's about 50+ cells that need referencing and I got to get this done for work.
Please help me. This is my first need to post on a Excel Forum as I've always found help or answers from other peeps or internet but this one is making me scratch my head big time.

Seemingly super simple, but I can't figure it out.
When I create a bar chart, the bars are horizontal. I want the chart bars to be vertical. It tried to rotate the chart so that it is vertical, but the "rotate" options are greyed out.
How do I get those bars vertical?

Good mornng - I am new to the forum - my name is Jena
My question is this - I have a large spreadsheet with multiple columns of information. I want to sort it by a certain column. I know how to do this. My question is, once I'm done with my work I want to sort it back to the original "sort" but I'm not sure how they have it sorted. I've tried to figure out how they have it sorted but can't. Is there some way to go back to the original sort?
Thank you for your anticipated help.
