A few months ago in Gapminder for Excel I made a simplistic mockup of Hans Rosling’s Gapminder presentation Debunking third-world myths with the best stats you’ve ever seen in Excel. It was fairly simple, with a single bubble marching across a chart, interpolating between yearly data points as a simple timer-based VBA procedure incremented.
An astute reader named Eric thought that the chart would be more effective if the moving bubble left a trail of breadcrumbs, as it were, the annual mileposts along the travels of the moving bubble. I took up the challenge, and it took less time to work up than it’s taking to write this post.
I modified the data somewhat, since it was made up anyway, so that the path traced by the moving bubble was more continuous. I also defined some names in the worksheet which contain the whole series of data from the first point up to the point where the moving bubble has reached.
Here is a summary of the names, if you’re playing along at home. The first three names were present in the first version of this chart, and were used by the VBA program in its interpolation routine. The next three names are the X and Y values and the Diameters for the bubbles. Finally, I’ve included the chart series formula for the new series.
Name Refers To FirstColumn =Data!$B$12 LastColumn =Data!$B$13 ControlColumn =Data!$B$14 AllYearsX =OFFSET(Data!$A$3,0,1,1,GapminderExcel.xls!ControlColumn-1) AllYearsY =OFFSET(AllYearsX,1,0) AllYearsD =OFFSET(AllYearsX,2,0) Chart Series =SERIES("All Years",GapminderExcel.xls!AllYearsX, GapminderExcel.xls!AllYearsY,1,GapminderExcel.xls!AllYearsD)
The workbook can be found in GapminderII.zip.

Thanks. I saw that Google has a motion chart widget that does something like this and though it was cool. I’d prefer doing it in Excel. Now I need to find a good data set to use it on. (Not just use it because it’s cool and end up confusing the point of the data)

Do you know how to get all of this into a Powerpoint so I can present that animation? Thanks

Anton -
You could keep the Excel workbook as a companion file to the presentation. Or you could embed the Excel chart (actually the entire workbook) into a slide. The embedded chart will be frozen during the slideshow, but in design mode, activating the embedded chart will allow you to run the animation.
With some VBA programming, it is possible to run the animation within the slideshow using controls you’ve embedded in the slide, similar to the controls on the worksheet. I haven’t done this, so I can’t say how it’s done.

Hi there,
I have created a small Excel add-in that seems very similar to what you have done here. My aim is to make it as straightforward as possible for the user to animate their charts – all that is required is to create a data table, create a chart from the top row of that data table and then use the add-in’s menu to run the animation.
It is freely available from my website – http://www.animatexl.com – and I would greatly appreciate any comments from any potential users.
Regards
Phil.
