Hurricane Sandy has taken front seat in all major news channels, papers, websites even in far off places like India. I hope & pray that our readers in US East coast are safe.
Today, lets understand the journey of Hurricane Sandy in this animated chart, prepared by Chris from Excel365.net.
Hurricane Sandy Journey – Animated Excel Chart
How is this animated chart made?
The basic ingredients of this chart are:
- An outline map of Americas
- Data of the storm since it was tropical depression (22nd October) to the time it crossed the coast (30th October)
- Lat & Long of the storm
- Wind speeds
- A scroll bar form control that shows only a subset of this data
- A VBA macro that animates the chart
Since all these techniques are previously discussed on Chandoo.org, I am going to list down the process in high-level with links to learn more.
- Set up a scroll bar form control
- Based on scroll bar position extract first n values only in to another table. Learn more: OFFSET formula *
- Use an outline map & bubble chart to plot circles along storm’s trajectory. Learn more: Olympic medals by country since 1900
- Change scroll bar values from 1 to ‘n’ using a vba macro, when triggered. Learn more: Creating a clock in Excel
- You are done!
* Chris uses #N/A based technique instead of OFFSET ranges in the chart.
