  • 1. blank cells
    Perhaps I am trying to use the wrong kind of chart... I have information in a pivot chart that I want displayed in lines. However there are some cells that have no information in the series I want to plot. But there is other information in the row, so it doens't ignore it as a blank cell. For example: Days Actual High Low 2 3 5 2 7 5 3 15 2.5 4 2 When I chart the actual series, it reads the blank as a zero and plots it as such. My columns in the pivot charts are averages. Is there any way I can get the chart to ignore the zero and still plot a line to the next point? I have tried using the excel options and the pivot chart options for ignoring blanks but it hasn't worked so far.
  • 2. excel 2007 trendline equation
    I'm used to see t trendline updating automatically when the source data change. Now this does not work any more. In the Q&A I read bout dynamic charts what does that mean ?
  • 3. x-y plot in Excel 2007 questions
    I am trying to make an x-y plot and the axis that excel uses are not what I want. I am comparing wages to 3 different outputs. I want wages on the y-axis and output on the x-axis, but excel does the opposite. I went to "select data" and did "switch row/column" and did not get the results that I am wanting. So my question is, how do I tell excel what I want on the x-axis and y-axis?
  • 4. Setting chart title.
    I am getting an ArgumentException with the message, "This object has no title." from the following code: chart.ChartTitle.Text = "Total Sales Comparison"; If I comment out this line the chart is created but the Title is "Chart Title". What do I need to do to set the chart title? If it helps here is the code I am using to create the chart: Excel.Shape shape = ws.Shapes.AddChart(Excel.XlChartType.xlLine, missing, missing, missing, missing); shape.Name = "YTDTotalSales"; Excel.Chart chart = shape.Chart; if (chart != null) { chart.SetSourceData(ws.get_Range(string.Format("{0}2:{1}{2}", (char)('A' + (baseColumn + 0)), (char)('A' + (baseColumn + 4)), currentTotalList.Count + 2), missing), missing); ((Excel.Axis)chart.Axes(Excel.XlAxisType.xlCategory,Excel.XlAxisGroup.xlPrimary)).TickLabelPosition = Excel.XlTickLabelPosition.xlTickLabelPositionHigh; chart.ChartTitle.Text = "Total Sales Comparison"; chart.ApplyLayout(3, missing); } Thank you.

It does not seem that it would be too difficult to set up Excel 
to do what you want. See the Wikipedia stub on Bland Altman. 
That's just what I did since I had not realized that Bland and 
Altman had arrogated the standard Tukey mean-difference plot, as 
is it is still known as in other fields.

I didn't follow the previous discussion, but here's a ready-made macro

1.Bland Rows

My spreadsheet has 250 rows and A thru AG in columns, all cells are bordered. 
 All of the columns are used if a row is used.  My sheet has 15% more rows 
than our highest use this year so that I am sure our office does not run 
short of rows (my workbook has 12 of these sheets because we track the info 
monthly and forward the sheets as filled out to other personel). 

My question is how do I print the sheets (only one month is printed at a 
time) to print only the rows that has been filled out, all of the sheet rows 
are continuous, we have no unused rows except for the ones left at the bottom 
that are unused.  when ever I print the sheets it always prints a few extra 
pages from the bottom that are just the gridding.  I don't want to have to 
delete all of the unused row before I print the sheet. 

2.Eliminating bland from Data Validation list?

Hi,

I looked around other postings but could not find the answer -- what I'm 
having a problem with is thta in my data validation list, I have a range set 
(which refers to column H) -- the number within the range can change, and I 
sort it every time it does change so that there are no spaces between values. 
 

The problem is that there are numerous blanks in the list at bottom, after 
the last actual value in the range.  Is there any way to get rid of those 
blanks?  I tried deleting (delete shift up) all blank cells after the last 
value and through the last cell (H65536), but this doesn't help.  Below is my 
code.  Thanks!


    With .Range("B2").Validation
        .Delete
        .Add Type:=xlValidateList, AlertStyle:=xlValidAlertStop, Operator:= _
            xlBetween, Formula1:="=dvrange"
        .IgnoreBlank = True
        .InCellDropdown = True
        .InputTitle = ""
        .ErrorTitle = "Please select value"
        .InputMessage = ""
        .ErrorMessage = "Please select a value from the drop down menu."
        .ShowInput = True
        .ShowError = True
    End With

3.plots sent to to a chart tab do not show plot & I loss the plot

I have a spreadsheet that has a chart tab with a plot of data from another 
part of the spreadsheet. Now, however, the chart is empty and when I try to 
send any plot to a chart tab the plot is lost and the chart tab is empty.  
This is happening now in all my spreadsheets the plot can be created within a 
spreadsheet but as soon as I move it to a tab the plot is lost and the chart 
tab has nothing in it.  !!!????!!!!

4.Removing Plot lines between plot points on a line chart

A 2003 file being opened in 2007. Contains a line graph. I wish to remove a 
plot line between two points. The lines right now or dotted, when I go 
through the process of entering into the chart options and click on "No plot 
line" nothing happens and the dotted lines remain. ANy suggestions? Or is 
this a converting issue going from 2003 to 2007?

5.plotting long plots

I have a HP designjet 110 nr plotter. I've created a plot that we nee
to show drilling activity. My first plot was 24"x36". Plot works grea
and to scale. My next plot was to be 24"x72". Now the charts will no
even display in Print Preview. I can scale back the plot where it i
about 48" and it will preview and plot, but I need it to go out eve
futher than 72 inches. I may go out as far as 30 feet.

I have images on the plot area and it will print it just fine at th
farther distances
