Unintended vertical grid lines in weekly case x-axis (example 4) #3
Description
Running example 4 in the sample script (weekly case), the first plot effectively only has two values on the x-axis, but there is still a grid with vertical lines at 2011.2 through 2011.8. It is unclear if this behavior is intended or if the plot should only display grid lines at the actual x-axis points. Please investigate whether this is the intended behavior and, if not, consider updating the grid rendering to match the available x-axis values.
