graph problem

[dmartin1953]

I'm trying to plot some data as a function of time- The data starts at 6pm (day 1) and ends 8 hours later at 2 am the following day (day 2). The graph shows the data startifn at midnight on day 2 followed by a gap from 2 am until 6 pm when the data is plotted from 6 pm until midnight.

i want the data to be shown as an 8 hour run from 6 pm until 2 am. I'm using the Mac version of Excel.

Thanks in advance.

Hi there, Welcome to the Board

In A1 I put the formula =NOW()
In A2 I put the formula =A1+TIMEVALUE("1:00:00") and scrolled it down.
I then changed the format of column A to h:mm.
This will now give you a continuous chart but will not show the day.
You could use another column in your source to display the day and time together if necessary.

Hope this is of some help

thanks for the help, but I can't get the formula to work.

Hi again

It still works for me.
In a new workbook, select a sheet and run this code:

Sub ChartTimes()
ActiveSheet.Name = "Test"
Range("A1:B1").FormulaR1C1 = "=NOW()"
Range("A2:B34").FormulaR1C1 = "=R[-1]C+TIMEVALUE(""1:00:00"")"
Range("A1:A34").NumberFormat = "dd/mmm/yy h:mm"
Range("B1:B34").NumberFormat = "h:mm"
Range("C1:C34").FormulaR1C1 = "=ROW()"
Columns("C:C").NumberFormat = "General"
Charts.Add
ActiveChart.SetSourceData Source:=Sheets("Test").Range("B1:C34")
ActiveChart.Location Where:=xlLocationAsNewSheet
Sheets("Test").Select
Columns("B:B").EntireColumn.Hidden = True
End Sub

This will produce a continuous time chart (as an example). Note that the hidden column B is the actual source of the data and is formatted "h:mm".

Hope this makes it clearer for you
