Challenge #91: Getting into the Weeds

Whew, this one was a doozy! I got some good practice on interface tools and reporting tools!


I did a few things differently than the solution in prepping the data:

Spoiler
* Grouped on year based on DATE (not on filename), since the 2012 file contains 2011 and 2012 data
* Stacked the primary and secondary weed types (the solution uses only the primary weed)

* I wasn't sure how to summarize the data, since there were multiple records per route and weed type. I tried looking around the CDOT website, but couldn't get a detailed explanation of the fields. I summarized by route and weed two ways:
    1) max coverage across the route -- OR --
    2) weighted average coverage using the coverage upper bound and length of road (for example, if the total route is 10 miles,and 2 miles had 0-20% coverage and 8 miles had 20-40% coverage, then the weighted average would be (2 * 20% + 8 * 40%) / 10 = 36% weighted coverage)

My app is pretty basic but it does the work

Hi! Here my solution :)

Struggled to recreate the chart using the Interactive Chart tool so decided to produce another table instead.

Used the new interactive chart tool! Not super intuitive, but I managed it in the end

Again a chance to practice reporting tools ... and some other, I don't use daily

I spent too much time figuring out that I can't build that side-by-side bar graph in Alteryx. Unless anyone figured out how to do it, I will stick with Tableau for visualisations. At least, I tried to batch build line charts (more suitable  in my opinion) and the percentages are from centered values from within the ranges.

 

Here's my take

Nice practice off interface and reporting tools
