We were extremely fortunate to have Ann Jackson join us on the weekly Wise Up Wednesday at The Data School. Originally she was going to take us through how she completed week 45. However, I thought it would be interesting for Ann to see how we approach the challenges. Ann pitched in a couple times with some hints to keep us from heading down the wrong path. We were able to build the chart in one sheet, including the headers whereas Ann used a text box for the headers.

For Workout Wednesday week 39, Rody challenged the Community to create a shaded area chart with a line on top and marks for each month. That's three mark types, but Tableau only supports two at a time. In addition, the axis label has to be vertically aligned, that is, each letter in the word has to be below the preceding word.

I was expecting some crazy polygon calculations from Rody, and perhaps that's how he approached it. I, however, was able to create the required view with only two marks and the text shelf. Before I get to how I came up with my solution, here's my submission:


For the dashboard layout:

1. I used a vertical container with a 50px blank on each side. 
2. The rest of the viz is in a horizontal container in the middle of the vertical container.
3. I added spacing to the outside edges of the black line to get the spacing right.
4. I added some spacing at the top of the parameter and the dynamic title.
5. The parameter is in a horizontal container with a blank on either side set to distribute evenly.
