Makeover Monday: When Do Turkey Vultures Travel the Farthest?
Eva posted these maps to makeover:
What works well?
- Using a map helps show the migration patterns.
- Using color to indicate the speed by which the birds travel (FYI, they're FAST!!!)
- Splitting the view between outbound and return migration.
What could be improved?
- Remove the latitude and longitude axes
- Remove the region labels
- Change the red/green colors for the middle two speeds
- Add a title so we know what the viz is about
- Make it interactive so that we can see the patterns of individual birds
What I did
- I focused on the distance the birds traveled. To do this, I exported the data to excel and added a column for distance which was calculated row by row for each bird. This then makes aggregating the distance easier.
- I created a calculation for distance per bird. This is a better measure than the average distance because the denominator is the number of birds, not the number of measurements.
- I create a marginal histogram to show the monthly/yearly patterns.
- I included filters to make it easier for the user to look at a specific bird or birds.
- I include the map for context and it draw a line for the pattern for each bird, whereas the original was a series of dots.
- I created a custom mapbox map that only includes the country borders (for decluttering) and has a background color that matches the dashboard color.
With that, here's my Makeover Monday week 4 2018 visualisation.

Great presentation Andy!
ReplyDeleteWould you mind if you share your techniques to calculate distance?
I saw your old post (http://www.vizwiz.com/2012/01/tableau-tip-calculating-distance.html) about how you calculate the distance between 2 points. However, you went a step further on this by incorporating timestamp.
I am trying to replicate yours but having a hard time.
Any tips will be greatly appreciated.
Thanks always for your helpful Tableau tips and amazing visualizations.

I used the formula from my blog post but did it in Excel instead of Tableau.
DeleteThank you Andy! That's what I did as well.
DeleteIt seems there is no simple solution to calculate a series of distance of different birds using only Tableau? I will update you if I find a solution to that!
