You seem to be missing the -ycommon- option of -graph combine- and -plotregion(margin())-. Nick n.j.cox@durham.ac.uk Allan Reese Under axis_label_options in the V9 graphics manual, the option x/ylabel(,nolabels) is described with the challenge, "Why anyone would want to do this is difficult to imagine." I've made an array of line plots, each pane demonstrating that a measurement varied very little over time. A nominal +/- 10% of mean line is drawn around each line plot, and the panes are stacked as a column with common time axis. Removing chart junk therefore involves removing all but the bottom xaxis line and labels (the line being close to each -10% reference line) but I did want to repeat the ticks to aid time-referencing. Here's the commands, simplified, for the last couple of panes: scatter y1 time, c(l) ti("Deviations from mean percentage measurement") yti("%", orientation(horizontal)) t2(lines at +/- 10% of mean) xti("") xscale(range(0 25) noline) xlab(0(4)24, nolabel) yli(0 +.28 -.28, lcol(gs4)) ylab(-.2 0 "0" .2 .28, angle(0) format(%3.2f) labsize(*1.2) ) yscale(range(+.28 -.28)) scheme(s1mono) plotregion(style(none)) name(g1,replace); scatter y2 time, c(L) yti(" ") xti("") xscale(range(0 25) noline) xlab(0(4)24, nolabel) yli(0 +10 -10, lcol(gs4)) ylab(-4 0 "0" 4 10 ,angle(0) format(%3.2f) labsize(*1.2) ) yscale(range(+10 -10)) scheme(s1mono) plotregion(style(none)) name(g2,replace); ... scatter yn time, c(L) yti(" ") xti("Hours") xlab(0(4)24) yli(0 +2 -2, lcol(gs4)) ylab(-1 0 "0" 1 2,angle(0) format(%3.2f) labsize(*1.2) ) yscale(range(+2 -2)) scheme(s1mono) plotregion(style(none)) name(gn,replace); * then to assemble trellis; graph combine g1 g2 ... gn, col(1) xsize(2) ysize(6) imargin(zero) scheme(s1mono); -------------------------- Making the Y axes line up exactly was hard; I'm not sure if it's achieved but it looks near. Formally, I'd like the ytitle to extend left from its start rather than right. Something I haven't achieved is to put the ticks on the 0 line of each plot rather than outside the plot area.
