An Excel Chart’s Journey Across Versions

Sometime back I wrote a post on making control charts using Excel. The chart was initially created in Excel 2003. The chart consisted of the plot values, the average line and upper & lower control limits. While the main data series was a line chart, the average, upper and lower control limits were plotted as dots of an X-Y and then were extended into lines using the horizontal error bars.

Excel 2010 vs Excel 2007 : Basic Performance Test
My first impression of Excel 2010 was that it 'felt' faster than Excel 2007. So one of the first things that I did was to take it for a test ride. Now, I must admit, testing isn't my forte. A long long time back when I was a developer, I used to write horrible code. I had a fancy for declaring variables like i1, i11, i111 (and so on and so forth) and seldom wrote comments that could explain ...

Sparklines in Excel - New Features in Excel 2010 Series
Excel 2010 introduces a new feature called sparklines. Sparklines are essentially miniature charts showing only the plot and pretty much nothing else (though you can turn on chart axis if you want).

Excel 2010 – Beta Review

Posted on 18 November 2009

Excel 2010 - Beta Review
Excel 2010 beta is out today. For those who read my review of Excel 2007, I mentioned that the chances of my being able to try out Excel 2010 anytime soon weren’t very high. Excel 2010, I thought at that time, and considering how Excel 2007 turned out, would simply be too big a resource hog to work with the hardware that my pc runs on. In that case I would have to give my faithful old pc ...
