Default Time-scale chart measured in hours & minutes

When you create a chart, or when you choose Chart Type from the Chart menu,
you are presented with a set of options. One is Line chart, another is XY
chart. They present the data with an identical set of formatting options;
the difference is in how they treat the X axis data. An XY chart treats the
X data as numerical, while a Line chart treats it as categorical. An XY
chart then plots time as a fraction of a day, but since times are fractions
and categories are integral in nature, the line chart plots times either as
separate equally spaced categories or as a series of points on a single
integer day.

That's why I've twice suggested using an XY chart type.

What do you mean XY chart? Currently it's in a line chart....

You missed my second sentence:

Plot as an XY chart.

Doing this shows every reading for the day in one column, regardless of
time.
I'd really like to have it spaced out accurately based on time as well.
Could
I be doing something wrong?

Combine time and date into a single column, and don't leave out any
dates.
Plot as an XY chart. Format the X axis using a date-time format.

I am hoping to get a time-scale chart using hours & minutes, as well
as
days.
I know the generic help response is that it can't be done, but it
doesn't
seem possible that this need hasn't been addressed. What is the
workaround?
Here is an example of my data set:
