Prevent Chart From Adding Interpolated Phantom Values
Jan 9, 2008
I have a dynamic chart that allows the user to select the starting and ending dates for the data range by using a scroll bar.
The dates in the data table are input daily and are generally in sequential order, however there are gaps between dates (eg. 1/4/08, 1/7/08), such as would occur over a weekend or holiday period. The dates are used as labels for the X-axis.
The problem is the chart interpolates the dates in the "gap" and includes them on the X-axis and plots them as zero values.
I would like for the chart to display only the dates and values actually in the dataset and not interpolate and include dates/assign zero values.
Haven't had any success in searching the forum. Can this interpolation be prevented?
I have an excel report containing eight or so worksheets. A user can make a number of selections with the report to change its context. E.g. to analyse different types of customers; high spend or low spend etc. Sales projections are then presented with several Excel Charts adapting to the user's preferences.
My problem occurs when the user makes a selection (they choose a ComboBox option.) This then triggers my code, which creates the data tables and graphs depending on their selection. The report is quite long so I have created two points in the same worksheet where the user can change the same customer selection option. (Basically, all I have done is create a second ComboBox which triggers the first). Again, this works perfectly causing no errors (other than the display error belowc)
However, when I change the second instance of the ComboBox a phantom copy of my chart is dumped on the current screen view. If I scroll off screen and then back again the phantom chart disappears. I need a quick solution to fix this bug until I have some more time to look at what's causing it. Therefore I simply want to add a line of code, which will scroll off screen and then return back to the same position. (Not very neat, but at least it will get rid of my duplicate chart). As I have screen updating turned off the user won't notice what is happening.
I'm working on a program, which gives me interpolated values of z from a digitized graph based on the cursor position or input values of x and y. Thing that bothers me for quite some time is how to get properly interpolated z value. I was using SADA (spatial analysis software), where I was creating a 100x100 matrix, but the interpolation methods there are not as accurate as I need.
Basically, from digitizing a graph I get a matrix:
Now, inputting x and y that are not in the matrix should give me interpolated value of z, which gets even more tricky when the axes are in log scale. The only idea that I have in my mind and that I think would work is this:
for each missing z, from zmin=0,625 to zmax=3 , every 0,001, I would make 1000 (enough accuracy in this case) xs and ys. How to automate the process.
I have created a population pyramid and want to add another chart on the secondary axis which I can do. The part which I seem not to be able to complete is getting the line chart secondary axis to read from the primary y axis. It seems to add a new axis, even when I delete this the line chart does not read correctly.
Adding some additional code to prevent someone from saving the workbook under a different name. Currently if someone tried to enter data after the allotted time period, it would allow them to in any "unlocked" cells. When exiting or trying to save the file with this new data, they will get a message stating something to the effect that this is a read only file would you like to save as another name, which would allow the user to circumvent what I'm trying to accomplish. The end result would be they'd need a new spreadsheet.
I have a piece of code that hides unneeded rows, it does work but it is very slow. This is in the worksheet part of the project. My problem is as it runs it "jumps" in to a function I have in a module that counts continuous rows. I would like to know why it is doing this and what I need to do to stop it? I have another piece of code that is structered exactly the same that hides unneeded columns and I do not have any problems with that. I know both pieces of code are dealing with rows and I think this is part of the problem but I can not see any reason why the first bit would call the second bit?
Dim C With Worksheets("CEN OAS"). Range("D5:D378") .EntireRow.Hidden = False End With For Each C In Worksheets("CEN OAS").Range("D5:D378") If C.Value = "" Then C.EntireRow.Hidden = True End If Next C
I am dealing with plotting large amounts of data (millions of cells) across multiple series. Everytime you click, add a new series or do anything it redraws the graph taking a while. This Is there are way to prevent Excel 2003 from plotting a graph until you are done setting it up?
how to resize the plotarea of a chart so that it wont overlap with the title. I can't seem to find the appropriate property to let me determine the height or the bottom edge of the chart title.
I do not seem to be able to consistently control word wrapping in the Category Axis area in the series of charts I create quarterly. The individual names appearing are basically the same, but sometimes they word wrap and sometime they don't. In the attached sample, sheet C2-Location: PPO chart is just the way it needs to be - NO WORD WRAP. But if you change that chart to another location it word wraps. (To change locations, go to sheet D2 which controls sheet C2 chart, and change the location to SGO.) It appears that the less bars in the chart the greater the problem.
I have spent 2 1/2 hrs trying to get in control of this. I have changed font sizes, changed the plot area, changed the grid lines scale, changed the cell size on the originating sheet (D2), removed the check mark in Auto Scale on the Font tab, and stretched/reduced the entire chart without consistent success. What is most frustrating is that twice I have "accidently" gotten a chart to all of a sudden not word wrap but don't know why because when I try to repeat what I think I did before, it does not work!
Additionally, at times it may appear correct on the screen, but when I do Print Preview, it is word wrapped! I have searched multiple sites and googled multiple Excel solutions as well as pulled out some books but cannot find any references regarding how to control this.
I have a link that is showing up under Edit/Links. I have tried to locate this link by highlighting all sheets and using the find command and using part of the file string however it is not finding anything. I tried this with a link that I know should be there and it takes me right to the sheet/cell its located in...
I remoted most of my number crunching stuff to a dll.
It work fine except for a few strange things that I observed like from time to time a strange message "Error in loading DLL" even though everything works fine. This message appears only when entering the main formula in the formula, and is no problem at all in usual work.
When I investigated, I noticed in the "windows task manager" that one instance of excel remains open even after I have closed excel. This phantom excel process is maybe related to the other problem I explained above.
Instead of calling a VBA function, it creates a VB6 object from this dll and uses the methods of this object. In this way I have remoted the number crunching functionality.
The main parameter passe in this process is a reference to the original workbook. I need it because the number crunching functions need to read data from the workbook.
I made it sure to terminate the life of the object properly on both sides by ad hoc obj=Nothing statements.
Still I think that the "garbage collection" or the "terminating" is the cause of the problem.
When copying sheets within a spreadsheet I receive numerous examples of the attached error message: when I search for the named range referred to in the source sheet it doesn't exist - I can only assume that it is a variable name that has been assigned somehow - but as far as I can tell, there aren't any macros associated with the spreadsheets in question that are generating the names that are displayed .. so unsure how the names are appearing. how to remove these phantom names so the prompt stops appearing?
NB: If I answer "No" to the prompt I must enter a different name - and if I do that, the system creates the new name in the copied sheet so if I then copy the copy on to another sheet the number of "named" ranges includes both the original "phantom names" AND the additional "phantom names" I've created as part of this process.
I am trying to add numbers from cells if it IsNumeric and for some reason in column K the macro doesnt recognize numbers after row 14?
The range column is "E4:E" Search criteria is the letter "R" in column "E" Then using OffSet, I go thru other columns and process data. Most of the macro works except for column K after row 14?
How can I add missing values to the axis in a pivot chart line chart? I have a numerical X-axis with values such as 0,1,5,8,14, etc. I have another set of Y values that correspond to the X values. If this was an XY-scatter plot I'd be able to plot X vs. Y and connect the dots for "gaps" in the X values. Since it's a pivot chart I cannot use an XY-scatter plot, I can only use a line chart. The line chart doesn't give me the ability to add the "missing" values, so it gives the impression that my data is more closely packed than it is. The data source is external to my spreadsheet, so I cannot add the values before creating the pivot table/chart.
I have the following code which puts a series onto a chart
With Charts("Test Chart") .SetSourceData Source:=Sheets("Data").Range("A1:B" & Nreadings), PlotBy:=xlColumns .Axes(xlCategory).MinimumScale = 1 .Axes(xlCategory).MaximumScale = Nteeth .Axes(xlValue).MinimumScale = Miny .Axes(xlValue).MaximumScale = Maxy End With
I would like to add a 2nd or third series onto the same chart using the same scale etc. How do I do this in VBA code? Whenever I add another line to add a series it just overwrites the first series I have shown here.
I'm trying to do something that I thought would be very simple for excel to do. All I want to do is show the average score of the data selected by the selectors in the chart. For instance, in the attached file, I have the following selection (AMER, North America, Canada & USA, Purple) and from this data selection I have 4 columns of data. I would like the chart to show somewhere on the chart the average of the total revenue (both columns) and the average of the GOP. Is there not a way of showing on the chart any data metrics?
I want to use 4 toggle buttons to be able to add and remove 4 different series to a chart. When the toggle button is clicked, a specific series is added to a chart, and when it is unclicked then the series would be removed.
The problem I am running into is that unless I add and remove each series in a specific order, I will get an error because I may be trying to remove a series whose series number is not on the series collection in the chart.
for example: if I remove series number 2 with the toggle button for that specific series, then the toggle button for series number 3 will remove the old series 4 (which is now 3), and the toggle button for series 4 won't work because series 4 will now have become series 3.
Therefore, would there be a way to remove a series based on the name of the series, rather than the series collection number?
c5 shows today() and I'd like c5.value to be the headline of a chart. Hence, in sample file the headline be changed to 05/03/2014 (and tomorrow to 06/03/2014..).
I have a worksheet where I am collecting data and a seperat Chart. The first part of this code which adds a new row in my table works perfectly fine, but the latter part (based on a macro recording) does not. I need to specify the relevant row for the new series in the bubble chart. The colums are of course the same.
I add Data Labels and select the percentages. This shows at Cat 1 having 12.5% of the sales (100 of 800 sales), Cat 2 having 12.25%, and so on..... However, what you don't see is the following data:
So based on 1,088 sales, Cat 1 at 100 is actually only 9.19% of TOTAL sales.
I understand what is happening, the chart is giving the percentage based on the data inputted into the chart.
I did consider adding an 11th category to the chart, which was the total of Catalogues 11-15. Whilst this does give a more accurate percentage figure (as now all sales have been inputted), it makes the chart look ****
Is there a way of either adding the 11th category, and then "hiding" it, so that the chart doesn't display it, but uses it's value to calculate Catalogues 1-10s percentage?
BTW: The reason I ask is that I could be dealing with anywhere from 30 to over 100 catalogues. So it's not ideal showing the others in 1 chart.
I have a simple Excel 2007 column chart which has names listed along the y axis for each column. Associated with each name in a small table is a colour reference. Is it possible to add a small marker (say a triangle or something) that aligns with each column?
Or possibly (or in addition) colour each column differently and in accordance with the assigned colours? I'm doing this with some vba code. but if someone can point out the general principle I should be able to work that in.
I have a simple line chart but I want to add an text description to each of the points. The data is driven by a pivot table so the text needed may change based on the drop down options.
If I was using the below data I would want the line graph drawn using the date and value, but the data label at each point to state the description.
Date Value Description 01/01/2010 90% Text A 01/02/2010 80% Text B
I know how to use data validation to prevent repeat values entered into a column on one worksheet using data validation. I don't understand how to do this across 12 worksheets (months of the year) in a file.
To be more clear: When I enter an ID in a column cell, I want that to be compared to all the other ID's in all the past worksheets and rejected if it has already been entered
All are column D The values entered are identification numbers and have both letters and numbers.
I Spoke too soon here, I am getting value errors, how to do it with conditional formating. I tried if cell value is =to #DIV/0! then white (dosent work). Richard this dosent seem to work mate =IF(SUM(F6:V6),"",AL6/SUM(F6:V6))
I want to a horizontal line in a chart. There are only two figures with me. One I want to display as a column chart. The other as a horizontal line chart. (I can use both excel 2003 or 2010, whichever is suitable)
I have a small macro that before closing the workbook will check a range ("C4:G24") on Sheet ("Data Checks"). It will then show a msgbox displaying each non "OK" result in the range. I want this to close the workbook if all cells in the range have the value "OK" and cancel the close if the msgbox appears. This is what I have so far...
Private Sub Workbook_BeforeClose(Cancel As Boolean) Dim r As Range, txt As String With Sheets("Data Checks") 'for each non "OK" result in range For Each r In .Range("C4:G24") If r.Text <> "OK" Then txt = txt & r.Text & vbLf End If Next End With If txt <> "OK" Then MsgBox "Please check:" & vbLf & vbLf & txt, vbExclamation Cancel = True End If End Sub
The problem I have is that although the msgbox displays the correct cell values if they are not "OK", it also appears and cancels the close if all cells in range DO have value "OK"???
I have a chart with sales data on one axis and inventory on a secondary axis. I have the average of each columns of data and want to add a reference line to each axis with it's average. I have added the averages to my data set, but it only adds the reference line to my primary axis. I actually began by manually inserting two lines to the chart (which seems asinine). They actually didn't print because they weren't actually on the chart, but rather just on the spreadsheet behind.
I want to add a user-form on a chart, which will have check-boxes that will allow me to select series(lines) that I want see and compare in a chart. Currently my line chart has 24 series (Lines) which makes the chart very difficult to view and looks very busy. How do I add list of check-boxes that will allow me to select one or multiple lines that I want to see at a time?
