I tried to improve some graph what I found online on the page of NewYork Times. The article is about the relationship between driving habits and gasoline prices in the period from 1956 until 2010.
In this article I found some interesting graph:
In this article I found some interesting graph:
It is informative graph was created 2010. I wonder how it will look like if I created this graph today with tableau?
And here is my result:
What become better?
- at first sight you can recognize deepest and highest prices as the color red signaled something negative. The blue means something positive in this case.
- I added the average line, so you can estimate if the prices are over or under the average
- I made x aches a bit longer in order not to be deceived with price development. If you let data talk it is important not to overdone with visualization. Some changes look positive (e.g. 1990) but prices are still in the negative area. On the original graph it is difficult to recognize this.
There are some hidden features what will be visible if you download the workbook. For example if you go along the price line with the mouse you will get information to exact price/year/mile. If you present this graph, you have a possibility to analyses this relationship step by step by clicking on the bottom "choose mile details" or play them in different modus. So you make your presentation interactive and keep the attention of your audience until the end. (BTW: People who is familiar with HTML can bring this graph to move. For this point check this video)
What become worse?
- The bottom ""Choose mile details" could be not recognizable at the first sight. So people can misunderstanding this inflation.
- The prices are shown only in the last mile details. All prices are visible if you download the workbook and go with the mouse along the price line
What do you think about that? It would be greater if you give me your feedback.
