Graphing a 7-Day Schedule/Roster/Rota

Hi guys,

I want to create a graph that shows how many people are available to work on a given day in the week. This is what I have so far:


The problem is, this graph pulls from a database that creates a new row for each new “availability” you add. The result is the data is skewed backwards if a given day has no “availability” at all. Like this:



(I removed day-4’s data, notice that day-5 and day-6 are now one day to the left)

At the moment I structure the graph’s input data like this:

  1. Search all [Schedules] and filter the list to only include shifts that are “Available”
  2. Group the filtered list by {Date} and count the number of shifts in each group

This creates the data for the graph, but with the flaw as described above.

How might I go about making the graph “aware” that a week has 7 days and show zero for the days where there are no shifts of the type “Available”?
