July 2011 Archives
I am very happy to announce that the Excel Hero Academy will be starting the 2nd group of students on August 1, 2011.
I know many of you have been waiting the better part of a year for this. The wait is almost over!
I am pleased to announce that the firs 100 students to enroll will be eligible for the Early Bird Special discount of $50. The actual buy buttons won't be in place on the enrollment page until first thing, August 1, Pacific Standard Time.
To claim the Early Bird Discount when enrolling, please enter the code: HEROBIRD.
If you are not on the EHA Interest List, what are you waiting for?

Sometime ago, I stumbled onto an interesting narrated chart at the NY Times that told the story of Oil's price and consumption.
I thought it would be an interesting challenge to recreate this chart in Excel. Here's the result...

I think this narrated and animated chart concept is very compelling for business presentations. I'm sure I would not have understood the story the chart tells, just by looking at a static version.
I love the fading images and how effectively they stir memories. They really add to the chart story.
There's a lot of interesting bits happening behind the scenes with this one. Jad's narration is a recorded WAV file from the NY Times original. I'm using DirectShow from VBA to play and pause the WAV file. It's important for the WAV file and the Excel workbook to be in the same folder, so please unzip them together before opening the workbook.
The animation plays at a different speed on every computer, so the big challenge with this project was to devise a way to keep the WAV file, which plays at a constant rate in sync with the animation, on every computer. I'd be interested in your feedback on how well the solution I settled on (synchronization points) works.
Tear this thing apart and figure out how it works. There are a lot of valuable techniques showcased with this chart project.

On July 1, 2011, I woke to a very pleasant surprise.
In my inbox was a message from Microsoft congratulating me on the fact that they had just awarded me an Excel MVP for 2011!
I am not exactly sure what this means yet, but it is exciting.
I just wanted to say thank you to Microsoft and to the anonymous nominators!
The physical award is being shipped currently. When it arrives I'll publish a photo here...
