for i to 9 do
for k to 7 do
p1[i, k] := plot(curve[i, k], x = 2.0 .. 5.0, labels = [xlabel, ylabel[k]], labeldirections = ["horizontal", "vertical"], color = [black], linestyle = Linestyle1[1], thickness = Thickness1[1], title = l[i], caption = cat("Fig.", i), legend = Legend[i]); p2[i, k] := plot(curvep[i, k], style = point, color = [black], symbol = [solidcircle, soliddiamond, solidbox, diamond, asterisk], symbolsize = 8);
plots:-display(p1[i, k], p2[i, k]) end do end do;
The following loop also does not display curves!
for i from 10 to 21 do
for k to 7 do
p1[i, k] := plot(curve[i, k], x = 2.0 .. 5.0, labels = [xlabel, ylabel[k]], labeldirections = ["horizontal", "vertical"], color = [black], linestyle = Linestyle1[2], thickness = Thickness1[2], title = l[i], caption = cat("Fig.", i), legend = Legend[i]); p2[i, k] := plot(curvep[i, k], style = point, color = [black], symbol = [solidcircle, soliddiamond, solidbox, diamond, asterisk], symbolsize = 8);
plots:-display(p1[i, k], p2[i, k]) end do end do;
The following loops dispaly the curves
(*** How come the following curves available did not show in the above for do loop?
for k to 7 do plots:-display(p1[1, k], p2[1, k]) end do;
for k to 7 do plots:-display(p1[2, k], p2[2, k]) end do;
for k to 7 do plots:-display(p1[3, k], p2[3, k]) end do;
for k to 7 do plots:-display(p1[4, k], p2[4, k]) end do;
for k to 7 do plots:-display(p1[5, k], p2[5, k]) end do;
for k to 7 do plots:-display(p1[6, k], p2[6, k]) end do;
for k to 7 do plots:-display(p1[7, k], p2[7, k]) end do;
for k to 7 do plots:-display(p1[8, k], p2[8, k]) end do;
for k to 7 do plots:-display(p1[9, k], p2[9, k]) end do;
for k to 7 do plots:-display(p1[10, k], p2[10, k]) end do;
for k to 7 do plots:-display(p1[11, k], p2[11, k]) end do;
for k to 7 do plots:-display(p1[12, k], p2[12, k]) end do;
for k to 7 do plots:-display(p1[13, k], p2[13, k]) end do;
for k to 7 do plots:-display(p1[14, k], p2[14, k]) end do;
for k to 7 do plots:-display(p1[15, k], p2[15, k]) end do;
for k to 7 do plots:-display(p1[16, k], p2[16, k]) end do;
for k to 7 do plots:-display(p1[17, k], p2[17, k]) end do;
for k to 7 do plots:-display(p1[18, k], p2[18, k]) end do;
for k to 7 do plots:-display(p1[19, k], p2[19, k]) end do;
for k to 7 do plots:-display(p1[20, k], p2[20, k]) end do;
for k to 7 do plots:-display(p1[21, k], p2[21, k]) end do;
