No need to.  There's been an item open for ages about this.  Its poster 
wanted the info to set up clickable an <IMG> map for GIFs on web page, 
but the real feature request is the same as yours.

More abstractly speaking, what these requests are about is a very rough 
approximation of on aspect of mouse interaction: coordinate mapping back 
to data values for static bitmap terminal drivers.

Version 4.2.2 has quite a lot of this already your finger tips, by way 
of gnuplot-defined variables GPVAL_X_MIN etc.  Adding GRAPH_XLEFT etc. 
shouldn't pose a major problem.
