new time series chart type
The New York Times (the printed edition, I can't find it on line) new
uses a very interesting chart type to display stock price trends. It shows the stock price trendline and straight lines from the base year indicating +\- constant percentage changes. They look something like this: http://lilt.ilstu.edu/gmklass/poverty.gif except: The x axis is scaled so the the percentage change produces straight lines. It includes several constant percentage change lines with the areas shaded: a plus or minus five percent growth rate will be shaded dark, a ten percent, shaded lighter. If I spent all day, I image I could produce one of these, but I was wondering if someone already had a macro that would do it. -- Gary M.

Gary -
Applying a log scale to the Y axis would produce the straight lines. There are several examples of such arbitrary axis scales on my web site: http://peltiertech.com/Excel/Charts/...tml#AxisScales The shading could be produced with stacked area chart series having carefully engineered values. - Jon ------- Jon Peltier, Microsoft Excel MVP Tutorials and Custom Solutions http://PeltierTech.com _______ "Gklass" wrote in message ...

Kelly: Thanks! I really like your website, you've done some really good work. Gary: I get the Boston Globe, not NYT. However, since the NYT owns the Globe, the 3 month DJIA trend charts are the same. To save you a day, I have reproduced a 90 day DJIA chart using the NYT/Boston Globe format. I've made the up and down %s user changeable. I've also made the 90 day period user changeable. As far as I can tell, the NYT/Boston Globe X axis scale is just plain linear. They simply calculate what the resulting DJIA would be 3 months out from the start date, then draw a straight line between 1st and last dates. this is different that the method used in your example. I haven't added the shading between straight lines. There are several add-ins that you could use if you want to add this feature. I posted the xls workbook on my site. You'll find a downloadable link at left bottom of home page. Let me know if it is close to what you were looking for. http://processtrends.com/ "Gklass" wrote in message ...
