#### Trendlines #3

```I am using Access-to-Excel automation
to bring in 2 Columns of data...Week Ending Dates,
& a Value.  These are the Source Data for a Vertical-Bar
Chart.

I have a 3rd column that uses this formula...
=IF(LEN(A8)=0,"",VLOOKUP(A8,TheLook,2))
to get Values for a Trendline...in "Column C".

I am NOT strong in Excel Charts at all, as I do
mostly Access Programming.

How can I take this "3rd-column" and assign that
to a Trendline?

TIA - Bob

Excel can calculate a trendline from a charted series, but I sense this
isn't the trendline you mean. To add the data in column C as another
series in the chart, choose Source Data from the Chart menu, and click
on the Series tab. Click on the Add button, then click in the Values box
and select the range of data for the new series. Click in the Name box
and enter a name or click on a cell with the series name. If you are
using the same dates, you don't need to change the category labels.

You should change your formula to avoid false blanks (""). The NA()
function returns the #N/A error, which might look ugly in the sheet
(conditional formatting can hide it) but doesn't plot as a zero in most
chart types.

=IF(LEN(A8)=0,NA(),VLOOKUP(A8,TheLook,2))

If you mean the added series is plotted as a column chart series, right
click on the series, select Chart Type from the pop up menu, then select
the chart type that you wish to use.

The #REF! error is being caused by the fact that the formula is in the same column as the first number in the named range _2x12. This is called the implicit intersection.

Excel won't open #3
About a month ago, I was using Excel, and closed the program in the normal manner and everything was fine.

Every time I tried to open Excel from then on, no matter whether I went through the Office Taskbar, the Start Menu, the Desktop shortcut or clicking on a spreadsheet, the computer froze.

Trendlines in graphs
Hi all! I have an interesting question. I am ploting a graph where the X axis is by months and the Y axis is the number of parts produced. Some months we do not produce any parts; therefore, the Y axis is "0" at that time. When I put a trend line on the chart, it sees the "0" as a computable data point. A line is then generated but is off from the true trend. The true trend can be generated if I remove all the non producing months. Is there a way to specify specific groups of cells in a column that you want to use in a trendline analysis--sort of hop scotch ...

Setting Wall Color in 3-D charts
When setting the wall color in a 3-D chart I have encountered a problem with the side wall and floor. They appear to have a embedded shawdow set. Is there anyway to remove the shadow so the walls and floor will all reflect the same color as Excel 2003 allowed? I don't believe you can change the side wall and floor colors. Would you consider changing to a regular column chart instead? A normal column chart might work better because it's generally thought that 3-D effects can misrepresent the visual interpretation of the underlying data. -- John Mansfield http://www.cellmat...

weighted trendline
Can anyone tell me if it possible to weight a linear trendline in excel? Like a calibration line where you can weight by 1/x where x is the variance at each point on the line. Hi, I don't believe that can be done with anything built into the trendline chart feature, but you can use the trendline formula in the spreadsheet and then apply your weighting to it. Then plot that rather than the built-in trendline. You can get the formula of the trendline from the chart by choosing to display it or in the spreadsheet by using the LINEST function or the related SLOPE and INTERCEPT func...

Increaseing Precision in polynomial trendline equations
How can I increase the precision in Excel's "Display Equation" option for trendlines? I am trying to fit a polynomial regression (trendline) to a X, Y scatterplot I have created. Excel's built-in trendline function shows a good fit (R2=0.9999) for a 6th order polynomial, however, If I re-plot the data using the coefficients from the "Display equation" option, the data diverge significantly. Apparently, for high order polynomials, you need to have a high level of precision in your coefficients (many decimal places accurate) in order to actually re-plot the same ...
