"If the datasheet data for the category axis contains date number formatting, Microsoft Graph automatically uses a special type of axis in your chart called a time-scale axis.
A time-scale axis shows a blank category for dates for which you have no data. If you do not want to see these gaps — for example, if you have data for 1-Jan, 15-Jan, 3-Feb, 12-Feb, and 2-Mar, and you want to plot the days next to each other - you can change the time-scale axis to a standard category axis.
On the Chart menu, click Chart Options, click the Axes tab, and then click Category under Category (X) axis."

Tie them together

"A link is a formula that gets data from a cell in another workbook. When you open a workbook that contains links (a linking workbook), Microsoft Excel reads in the latest data from the source workbook or workbooks (updates the links).

Use links when you want to maintain information in a single workbook, but also use the information in other workbooks. For example, if your product prices change frequently, you might keep a master price list.
Other workbooks that use the price data in calculations, such as purchase orders, inventory valuations, or sales estimates, can create links to the price list workbook so calculations always use current prices. When prices change, you only have to enter the new prices in one place."

1. Open both workbooks.
   
   
2. In the source workbook, select the cells you want to link to and click the Copy button.
   
   
3. Switch to the destination workbook and click the upper left cell of the range where you want the links.
   
   
4. On the Edit menu, click Paste Special, and then click Paste Link.

And a Functional New Year

This hilarious clock is the perfect accessory for any Excel power user. Each numeral has been replaced with a suitable Excel function that will evaluate to that numeral.

We've used one function from as many function categories as possible to really provide a broad range of functions.

=FACT(3) - The FACT() function returns the Factorial of a number. The Factorial of 10 is 10x9x8x7x6x5x4x3x2x1. This function is great for statisticians calculating combinations and permutations. In our case, the Factorial of 3 is 3x2x1 or 6

"Sometime before the year 3,000, Microsoft will hopefully increase the number of columns in Excel (Hey, I can dream can't I). The challenge before you is to write a function that converts a column number to its letter equivalent assuming columns go to ZZZZ. That’s about 450,000 columns - maybe more than I need."

DelphiForFun.org: converting polar coordinates to Cartesian coordinates.

"Students of analytic geometry, (the kind that combines algebra and geometry), often work in one of two coordinate systems: Cartesian or Polar - and frequently must convert from one to the other.

The Cartesian system locates points on a plane by measuring the horizontal and vertical distances from an arbitrary origin to a point. These are usually denoted as a pair of values (X, Y).

The Polar system locates the point by measuring the straight line distance, usually denoted by R, from the origin to the point and the angle of an imaginary line from the origin to the point, θ, (Greek letter Theta), measured counterclockwise from the positive X axis."

Unencrypted

"Word, Excel, and PowerPoint have been able to password protect documents for several versions by setting the 'password to open'. What we felt could be improved was the ability to enforce password strength rules, similar to what may be required when logging into your computer at work."
