I have a table with readings taken at irregular intervals.
I want the data points to be plotted along a continuous axis but when I try
to do this all the data appears against the date only and the time is ignored.
I have tried setting the x axis as time series but this doesn't work.
I can't change the units to anything but days.
Can anyone suggest a solution.
TIA

Peters:

You are using a Line chart. Line charts do not let you plot less than 1 day
intervals.

I use XY (Scatter) plots for data with hours:minutes.

I suggest you change your chart type to XY then set your X Axis interval to
desired start - stop date-time and intervals.

Excel stores dates as number of days since January 1, 1900. So your dates
will look like 38867 or something.
Time is stored as fractions of a day, so 6 AM is 0.25.

That means that Excel date and time as I write this is 38867.4130. The good
news is that you can enter 5/29/06 9:54 AM and Excel will recognize it for
start value.

You can specify your interval by entering time units. For a 3 hour interval,
enter 03:00:00 , for 15 minute interval enter 00:15:00 , etc.

You have complete control over the X axis number format by using the custom
format option. You can use d:h AM/PM to show day & hr with AM/PM.

If you just want time, then h AM/PM or h:ss AM/PM.


I have some examples on my site processtrends.com
