    graph dates revert to 1900

    I am attempting to plot my investments value against dates with Excel 2000
    in a Windows XP SP2 system
    I have over 750 date rows, with gaps starting in 2003
    When I choose a scatter chart, the dates on the chart revert to Jan 1, 1900
    It was working up until the number of rows exceeded 699.

    Is this a problem with Excel? Is there a limit to the number of rows that
    can be used?

    Richard -

    A scatter chart series can have no more than 32,000 points. So that's
    not it. I suspect there's a bit of nonnumeric data at about row 699 or
    700. If it looks like a number but it's left-aligned in the cell, this
    could be the problem. Make sure the cell has a date or general format
    (not text), then copy a blank cell, select the bad cell, and use Paste
    Special from the Edit menu, with the Values and Operation-Add options,
    to try to fix it.

    I can plot this range of data, so it is not bad data. I now have several
    plots, one for each year. The problem only occurs when I choose more than
    699 rows (any 699 rows).

    What are these gaps? Is it a formula that returns "" to look like a
    blank? A chart doesn't treat "" as a blank, it treats it as text, with a
    value 0. January 0, 1900 is day 0 in Excel's calendar.

    Re: graph dates revert to 1900

    The dates are not in a 1-2-3-4-5-6-7 order, because the stock market is not
    open every day. They are typically Monday through Friday and then the next
    date is Monday again. Hence I use the scatter plot so that there are no
    zero values for the days the stock market is not open. Again, I can get a
    good plot up to, but not including 700 rows. I have a good plot from row
    600 to row 743 now. I just cannot capture more than 699 consecutive rows.

    Re: graph dates revert to 1900

    additional information. There are no formulas in this data.
    The dates are added by dragging a corner down to create consecutive dates.
    Then I delete the rows that have dates when the stock market is not open.
    I fill in the value at the end of each day as reported by my the brokers
    web page.
    I have used this data now for more than 4 years. but finally the number of
    rows exceeded 699 and the plot automatically changed the dates to January
    1,1900 to 1904.
    If I graph any number of consecutive rows, less than 699, I get the date
    printed in column one.

    Can you copy your date data here? We may see something you didn't see.

    You can use a line chart, and eliminate the weekend gaps --
    Select the chart, and choose Chart>Chart Options.
    Select the Axes tab
    For Category (X) axis, choose Category.
    Click OK

    Richard -

    You have supplied no information that could explain such a problem with
    the chart. There is nothing magical about the number 699. If the data is
    in fact valid numerical data, this is not expected behavior.

    I rarely do this anymore, but I'll offer to look at your data. Email it
    to me (not to the newsgroup); remove the appropriate characters so the
    messae goes through.

    Richard -

    Cell A728 contains .12/29/2004 instead of 12/29/2004. The dot turns this
    value into text, and interferes with a time scale axis or an XY value axis.

    To find such a problem value, select the column, then use Edit > Go To
    (or CTRL+G), click Special, then select the Constants option, and check
    only the Text checkbox.
