Yes, you are right. I didn't stop to check that the output was correct,
only that it did in fact print hexidecimal values.  If you call
sprintf from the gnuplot command line then the conversion to integer 
happens automatically, but apparently the mousing code does not make
that check.

I don't know of one.


If it helps any, you could use the "bind" command to attach a 
command line formatting function that does the job:

  bind h 'pause mouse; print sprintf("%x %x", MOUSE_X, MOUSE_Y)'

Now if you hit the h key while the mouse is in the plot window,
the next mouse click will print the X,Y coordinates of the click
in hex.  It doesn't give you continuous readout, but perhaps it's
good enough for your application.  

With extra work you could even have the coordinates printed to the plot 
window rather than to the console.  See the demo "mousevariables.dem".
