data range referrences

Hi,

I have a chart which relies on the data in a table with 29 rows.

Occaisionally, I want to only use 28 rows as my data set for the chart.

I can manually enter a named range into the dialog, and upon entry, it
automatically ,morphs it into the string that describes the data range
(worksheetname, data set). When I manually type in the other named
range, it flips to the shorter named range in the table.

How can I inject that into the chart's data dialog on the fly?

I have tried to reference cell locations that have the named range name
in them. No worky.

I know it is possible to pass this value to the chart layout, but I do
not know how.

Anyone?

This post has some VBA techniques near the end:

So you are saying that this is the best way to handle say leap year?

I was wanting to get along without any VB code. Oh well.

The data table for the 29th day would only receive data if there were a
day 29, a leap year. So I leave the table at 29 rows, and only select 28
rows for the chart. On leap year, I want to select 29 rows as the data
set referred to by the chart. All my other months' days keep track with
whatever year is being done, and February does too. Just not the chart.

I may have to explicitly call the sheet name, not merely the range name
I declared. I will try that, and get back to you. Your stuff is nice,
but I don't think I actually need a dynamic table to accommodate one
single additional row every fourth year. :-) The table is fine. The
chart needs to be able to be dynamically defined by accepting named
ranges as data range input. That I can switch in once every fourth year.

I mean I know I can make a separate chart and refer to that chart on
leap year and the other during the interim, but is that the most elegant
solution? Can I merely make another chart below the first February chart,
and make it a 29 day reference, and I guessI don't have to worry about
the year, since one 365th tick not filled would be barely noticeable.
Seems like a kludge for me to simply add a leap year chart on my February
Plot sheet, such that any monkey can tell which set of dual data is valid
for the year they are in.


Hmmm... divisible by 4, by 100, by 400... What's all this leap year
crud?!

If you can use a defined name for the X and Y values for each series in the
chart, you can build dynamic charts that don't use VBA. Somehow when I read
your description, I assumed you didn't want to do that. The defined names
only work for the individual X and Y values, not for the total source data
range.

Perhaps the best way to do this is to define two February tables and do
a simple VB leap year test and set a value based on the test results that
hides one or the other table, and that chart always looks at only the
active table. Sound good?

Or two tables AND two charts, and the VB script merely hides the two
that are not pertinent in the year selected.

I guess I don't understand what you're trying to do, and how you're going
about it.

I developed a workbook which contains 12 month 'tables' (worksheets)
that allow two patient test data entries per day.

There are 12 monthly charts that track the test results. I also have
one 365 day chart.

My February month is 29 rows on a leap year, but only 28 otherwise.

The chart will have an error as will the year unless I handle leap
years (or non-leap years) such that the monthly chart and yearly chart
track correctly, according to the row count on the February sheet.

I was thinking of simply making a duplicate "table" a few rows below
the current table, and remove the 29th line from one, and have the use
apply test data to the right one, or run a macro to hide one table.

It still need two charts (three counting the additional annum chart)
for February to keep the error out, so I was wanting to dynamically
declare the chart spec. It appears I may be able to one axis at a time,
just not the data block itself, which is what I was trying to point at.

So, I thought I wanted a test for leap year, and would likely have to
develop a little engine to give the user the access to the right one
only, and the right chart(s) would get declared, or referred to.

So, my other solution was simply to make two tables on the same sheet,
and two charts on the same chart sheet (February), and make a little test
to hide the appropriate ones.

That was as opposed to dynamically declaring things after testing for
the leap year "flag setting".

Anyway, my first page has the Year, name (patient), date, and set
points for the tables to show red values at, and the doctor phone number.
That data gets referred to on each sheet and the month's date column
fills in the day of the week based on the year selected. Those
selections do cause date entries to transit from 2/28/xxxx to 3/1/xxxx
correctly on non-leap years, and also on leap years after passing
2/29/xxxx, so I could test for that somewhere. Otherwise it screws up my
Feruary sheet. :-)

Not sure if I related this very well.

Make your life simple. Suppose your dates are in column A, from A2 (Feb 1)
to A30 (Feb 29). Put this formula into cell A30:

=IF(MONTH(A29+1)=2,A29+1,NA())

This puts Feb 29 into the cell on a leap year, or #N/A otherwise. The #N/A
will not be plotted in an XY chart or a line chart, and the data will
progress in one step from 2/28 to 3/1 on non-leap years.

That 'IF(MONTH' test segment is what I was looking for. My third month
is on a separate sheet and will always read as the first day of the third
month on the first row. I am doing this for Feb only and this will allow
me to selectively fill both the date column and the day of week column,
which also shows up in the chart.

So this will make the 29 row blank (#N/A) on other than leap year, and
that blank row will not get used on the chart sheet, even though it is
based on the 29 row range? That is what I gathered from the letter part
of you response, and this will even keep that row out of the 365 day
years.? I think this may be exactly what I was after. This switch, in
fact is short and sweet, whereas I was trying to switch entire charts or
worksheets on which that given month would be based on.

I will let you know. Thank you.

All true. I tested it before posting to reassure myself that my memory was
correct and to help with the description.
