Jon,

I have a similar chart for blood pressure: day/time and systolic/diastolic and pulse. When I select XY chart, all options for Axis (Automatic, Category, Time-Scale) are grayed out whether either or both of the axis boxes are checked. All I get are times, and those are all 12 AM. Cell formats are date, time, number for the data. Any suggestions?

I'll be glad to send screen shots if they would help, or the actual file.

Also, the times format vertical in a line chart, but the dates will not and I cannot find any place to do that, though this may change if the scatter chart actually works.

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.

Time-scale chart measured in hours & minutes
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:

Date Time High Blood Pressure Low Blood Pressure

Plot as an XY chart. Format the X axis using a date-time format.

I'd really like to have it spaced out accurately based on time as well. Could
I be doing something wrong?
