Altering the range that is plotted by a chart via VBA
 

Good morning all.

I haven't really done a huge amount on charting, so I'm sure you'll think
that these questions are a bit simplistic, but here goes!

I plot a chart from a worksheet that contains three columns of data - the X
axis contains week numbers, and is in B29:B54. Actual hours are entered in
F29:F24 and cumualtive hours in G29:G24. The cumulative formula is of the
form: =SUM($F$29:F29)

So, each week, in order to plot another week's data, I have to copy this
cumulative formula down by one cell, which, considering I have a lot of these
reports, is a bit time consuming.

If I replace my cumulative formula with something that displays a zero or a
label if there is no corresponding weekly actual, the cumulative chart line
plummets down to zero, which makes the charts look unprofessional. If I
replace it with something that picks up the previous week's cumulative value
if there is no corresponding weekly actual, the cumulative chart line goes
across at a value equal to the latest cumulative, which also doesn't look too
good.

So, the question is, how, in this week for example, can I have my chart area
as b29:B54 (x-axis);f29:f54 (actuals); g29:f40 (cumulatives), but next week
extend
my cumulative plot to g29:f41 (i.e. extend it down by one week)?

Eventiually, I'd like to etend this idea to plotting a rolling 12 week
chart, so to start, it would plot b29:B38 (x-axis);f29:f38 (actuals); g29:f38
(cumulatives) then the next week, b30:B39 (x-axis);f30:f39 (actuals); g30:f39
(cumulatives) and so on, but one thing at a time.

If anyone has any good pointers as to how I might achieve some or all of the
above, I'd be extremely grateful.

Regards & thanks in advance.

Altering the range that is plotted by a chart via VBA
 

Got a reply off of the Excel-L mailing list. Had to move the
".ChartType = xlLine" line up higher. Moved it to right after chart
creation. I could have sworn I'd gotten errors with that line up
higher before. Oh well.

You replied to the wrong thread.

Sometimes putting .ChartType up too high will cause an error. If you specify a
bubble of stock chart type before specifying enough data to populate that chart
type, it will crash.

Thanks to all who replied.
I eventually achieved what I wanted by plotting the chart against named
ranges, and using VBA to redefine the ranges to which those named applied.
The charts automtically updated based on the redefined ranges.
I shouldn't have been so lazy!

Regards & have a good weekend.
