The topic for the first #SportsVizSunday of 2020 is personal health data. I took some leeway with the topic and looked at my golf handicap index and scores. I normally walk the golf course and golf impacts my mental health (sometimes positive and sometimes negative). There were a few times this year where I thought about buying a boat.
For #SportsVizSunday, I wanted to look at where my index fell in relation to other women who keep a handicap and highlight the scores that count towards my current index. As with most public work I do, I like to keep it simple. I spend a lot of time during the week working on dashboards so in my free time I tend to keep it light and simple.
The 2019 season was a bit all over the place for me. I struggled with my irons for the last two seasons and that definitely impacted my score. While that aspect was off the rest of my game was in good shape and that helped me get my handicap index down to an 18.4.
I play most of my golf at two different courses and wanted to see what my score and differentials looked like at those two courses. I felt like I played better at Furnace Brook because I hit my fairway woods and hybrid more than I hit my irons. The data backed that up. I scored better (based on differential) at Furnace Brook than at William J Devine.
In 2020 I’m going to track more of my golf stats and visualize them to see where I can get better. I know where I struggle with my game, but, seeing the data makes it a bit more real.
Last month’s Sports Viz Sunday was the Masters. I created 3 different vizzes using Tableau public.
The first one I created looked at how closely contested the Masters usually is. I’ve always felt that Masters Sunday was the best TV viewing day of the year and looking at the data backed that up. The tournament has only been won by 5 strokes or more 5 times.
Overall I like how this turned out. The one thing I would change is the title. I don’t feel that it gives a good take-a-way of what the viz is about.
The next one I did was on Tiger’s 1997 win. Tiger won by 12 strokes the largest margin of victory (as of this post). I wanted to see round by round how much better Tiger was than the average score for the day. Tiger is known for wearing red and black on Sundays and I used the color scheme in honor of that.
This is a simple viz and the goal was to highlight how good his 2nd and 3rd rounds were in relation to the field average score. There was a Twitter discussion about showing the better score on the bottom of the viz. In golf being under par is good and while it may seem strange to see better on the bottom I think it make sense when you are looking at golf scores. If I was showing tournament position (first place, second place etc.) it makes sense to show them at the top, but, I believe when showing in relation to par at the bottom of the viz makes more sense.
The 3rd viz looked at 1956 Masters where Jackie Burke Jr started Sunday 8 strokes behind Ken Venturi and came back to win by 1 stroke. I wanted to show round by round how well Venturi played for the first 3 rounds and how steady Burke was. I’d like to do a more in depth analysis on this to show how great Burke’s final round was. There were only 2 players under par on Sunday and Bobby Jones said it was the toughest weather conditions the Masters had been played in. This is my favorite of the 3 and hopefully I’ll expand upon this with a more in depth analysis.
I was excited that Cole Nussbaumer Knaflic’s Storytelling with Data current challenge is to create a basic bar chart. She says “The #SWDchallenge this month is to create a basic bar chart. Nothing fancy. No need to stack it or do anything else crazy.” I love a good bar chart and have been known to say “don’t underestimate the power of the bar” more than once.
For this challenge I used data from the 2017 Masters to show which holes had the highest percent of scores over par.
At first, I sorted the data in descending order so the top three were together at the top of the chart. For other data sets I think this works, but, for this I liked keeping the holes ordered by the hole number.
I debated the bar color for the top 3 for a while. I wanted to use the green to tie with the Masters theme. I decided against that because people tend to associate green with good – if I were showing the 3 easiest I would have used that. I tried orange, a maroon-ish red, dark gray, and brown but I didn’t love any of those choices. I had my husband look and he suggested that I color code them in multiple shades. Instead of shutting that down immediately I changed the scheme to show him what it would look like and asked do the top 3 still stand out? When he agreed that it didn’t, I switched it back to a two color scheme and he suggested the purple and I think it pops.
Initially, I labeled the bars and tested out different alignments. I felt that the chart was too busy with the bars labeled. I needed to add the percent over par to the chart so I added it next to the hole name. To do this in Tableau add your measure to the row shelf and change it to discrete.
I don’t have any annotations on this chart and if you aren’t familiar with golf over par may not resonate with you. I am sure some folks would suggest adding text to explain over par but I opted not to because I liked the clean look and felt that my title got the point of the chart across.
