You don't need a library for that,
just do:

var secs = 60 * min + sec;

[This is primary school stuf]

Why go for libraries, Javascript clientside plotting is fast and logical.

Could there be unformatted strings?

The "bar values" could be in floating divs.

===========================

This is from 2003 [the view-source is outdated]:

Or you can use floating color filled divs of any size.

Or you can let do it serverside on their server.

This is not a helpdesk forum, but usenet.
Here the asking party does not define the constraints of a response.
You do not determine what another should think useful.

I think my admonitions are very useful for you, as you are using a wrong
concept. position:absolute; positioning is the way to go here.

You are forgetting I showed you a nice way to do this with serverside
Javascript and CSS. Please look back and tell us what is wrong about
that idea.

Are you advising your client to do this without serverside scripting?

> I and my client are not interested in me writing a charting package.

Wel if you are a professional you are the doctor. You should have the
lead in how the result should be generated. If you do not do that you
are mistreating your client, even though he wants you to.

If you are the taxidriver your client says where he wants to go, but you
decide about the adhering to the trafficrules, because you must assume
he realy wants to get there safely.

So you are not asking for a Javascript solution at all?
If so you chose the wrong NG.

> Anyone else have any recommendations?

Not if you do not ask for Javascript scripting solutions, methinks.
