How do I insert a placeholder in a plot where I don't have data?

I'm making a plot from two columns/variables in my data table where one of the variables is the day that the data was collected on. I want to look for trends/patterns in my data as the number of days increases. However, there are certain dates on which I did not collect any data. So I'd like to insert a place holder on the dates when no data was collected and include these in my plot. Is this possible?

" I'm trying to find a way to prevent my plot from dropping off to zero on the y-axis..."
That's why I asked about "showing" versus "nonshowing" markers.
Use NaN or (NaT if x-axis is datetime)
It would be much easier to write actual code example if we knew what your data format looked like -- still for the purpose the timetable or a table with the time/date column as a datetime would make it drop-dead simple.

You could use interpolation to identify where the "trend" would be at the missing data point, and plot the interpolated values as a different symbol.
