I'd prefer something like this:
xy:makelist([x,exp(-x*1.0)],x,0,10);
/* plot with line segments */
plot2d([discrete,xy]);
/* plot with points */
plot2d([discrete,xy],[lines,"no"],[points,"yes"]);
/* plot the curve cos(x) using lines and xy using points */
plot2d([cos(x),[discrete,xy]],[x,0,10],[lines,1],[points,1],[pointsize,3]);
Comments:
1- openplot_curves accepts both [[0,0],[1,3],[4,6]] and [0,0,1,3,4,6]
to plot the points (0,0), (1,3) and (4,6). It would be nice that
plot2d did the same.
2- I'm still not convinced that gnuplot is the final solution, and I still
use openplot most of the time. Removing "gnuplot_curve_styles" from
the options would make the syntax more general and the options that were
not yet supported by other graphic systems could be silently ignored.
Notice that for openplot_curves it would be very easy to change the
current tcl-specific syntax "{plotpoints 1} {pointsize 3}" by
the syntax I'm proposing above (I've already done it for plotdf).
3- I have no preference among things such as [points,1] or [points,"yes"].
If they both can be accepted, even better.
