I've used Quickplot (http://quickplot.sourceforge.net/) for similar
purpose. It's not the most elegant solution since the chart viewer is
external, not embedded to your program, but it works, zooming and all.

You simply need to create a program that convert the log file into list
of points and pipe it to quickplot or save it into a file and point
quickplot to it (look at the command line options).

The chart navigation is a bit unusual, but is efficient to work with
once you get used to it.
