Okay, in my exploratory project I currently have a form I set up
with Qt Designer that includes a QwtPlot on which I plot (in code)
my data of interest.  (This is a basic 2D line / scatter plot that
will ultimately have multiple -- two or three -- data series on it.)

So the path of least resistance to test-driving your charting package
might be to replace the QwtPlot with a QWidget and promote it to
(in the Qt Designer sense) a ZPlotWidget.  (I'm assuming that you
haven't packaged your plotting components as Designer plug-ins.)
Would this work?

What files would I need?  Presumably some of the ZtPlot header
files, for example those used in the example listing you posted
on the developer forum.  I would also need implementation code.
Could I just add the relevant files (headers and implementation)
to my project?  That is, copy them to my project directory and
add them to my .pro file?  That might be easiest for a test drive.

Or would I need to build a ZtPlot library, and link to it?

By the way, I am using Qt 4.6.1 and mingw g++ 4.4.1 (a TDM build)
for the project in question.  The path of least resistance would be to
keep using those versions as my platform, but I suppose I could use
this experiment as an excuse to upgrade.  What Qt / compiler versions
are required by your charting package?

So, if I wish to subject myself to guinea-pig-dom, what would I need
to get from you, and how should we best proceed?
