Then select Single value (dropdown). This will allow the user to only select one week at a time.
Tableau does not allow you to concatenate integers with strings, hence why we make the date functions into strings. Note: Each date function needs to be wrapped in the STR function to turn the integer created from the date functions to a string.Here is an article from Interworks, that gives a good explanation about the different date functions in Tableau, but I will also go over the different elements in our example below.
Use the formula shown below to create a field with the date format mentioned earlier. Name the calculation Week with Date Ranges, or whatever else you prefer.Create a calculated field by going to Analysis > Create Calculated Field.This should automatically create a line graph if it doesn’t, select a line graph from the Show Me tab. Then drag Cost: Total $ from Measures to Rows. Drag Collision Date and Time from Dimensions and into Columns.
2018 CALENDAR BY WEEK NUMBER HOW TO
This guide will assume you already know how to connect to your data and create a new sheet. For the purpose on showing you how to create a weekly filter with the date range, I will show the total cost of damages to airplanes because of wildlife over a 15 year span (2000-2015). In this guide, I will be using the FAA Wildlife Strike data set found in Tableau Public (I will do future blog posts actually analyzing this data set). Here is a step-by-step guide in how to create this weekly filter. In this instance, I will then have the dates arranged by earliest to latest. I particularly like using this format because when you show the filter in Tableau, it will sort first numerically, then alphabetically. YYYY-Week X: YYYY-MM-DD to YYYY-MM-DD, where YYYY is the 4-digit year, MM is the month, DD is the day, and X is the week number. When creating this weekly filter, I like to use the following format: This issue can easily be fixed by using a calculated field and dragging the calculation into the filter section. As you can see, instead of being able to see an individual week, the viz will show the week selected for every single year in your data set. If you wanted to see how Week 1 would compare to Week two over multiple years, I guess this would work, but I think it would be much more useful to be able to see the weeks by itself instead of grouped together. For example, if you have data from 2016 through 2018, when you filter for Week 1, you will see the data for Week 1 of 2016, 20. What Tableau will do is create the same filter using the week numbers, but the data for each year will be grouped together by week number. The filter becomes even harder to understand when you have multiple years of data. I would want to know that Week 2 in 2018 is January 7 through January 13. As the user looking at the dashboard, it would be useful for me to know what date ranges these week numbers pertain to. Although, Tableau is able to identify what week number a particular date is in, when it is being used in a filter, all you will see is Week 1, Week 2, Week 3, etc. Tableau handles dates very well, but when trying to filter your dashboard by week, it leaves a lot to be desired from the standpoint of the user. I will be going over how to create a filter to include a date range with a week number. The less questions, the better! In this post, I would like to go over one simple thing that can make looking at a weekly dashboard a lot easier for the user. Basically, we want to create it so the user will have no question in their mind to how each piece of the dashboard functions. When working on a dashboard in Tableau, as the creator, we want to make it so anyone can be able to navigate the dashboard as easily as possible.
