Yep, see for example

http://www.physik.tu-dresden.de/~baecker/python/gnuplot.html

I.e., you just have to do send
"set mouse" before you start any plotting.

Further information from `help set mouse`
"""
 X11 specific implementation details: Mouse support is turned on by
default if
 standard input comes from a terminal (tty). Mouse support is turned off
if
 standard input does not come from a tty, e.g. a pipe. If you want to use
mouse
 support while writing to gnuplot from a pipe, the mouse must be turned on
 *before* starting the x11 driver, e.g. immediately after startup with the
 explicit command `set mouse`.
