I plot on the same graph Text and Tint, from octave :
... various settings including naming colors (blue = 9, green = 3)
#TExt
plcol0(blue);
plwid (width);
plline(x, temper(:,text));
legende(1, "T Ext", xmin, xmax, ymin, ymax);
#Tint
plcol0(green);
plwid (width); # needed to set width again <-----------------------
plline(x, temper(:,tint));
legende(2, "T Int", xmin, xmax, ymin, ymax);
function legende ( num, text, xmin, xmax, ymin, ymax )
## draw legend on top left of the graph.
## (or top right if xmin > xmax ....)
##
dx = (xmax - xmin) / 20.;
dy = (ymax - ymin) / 20.;
x(1) = xmin + dx;
x(2) = x(1) + 2 * dx;
xt = x(2) + dx;
y(1) = ymax - num * dy;
y(2) = y(1);
yt = y(1);
plwid ( 6 );
plline (x', y');
palette; # colormap with names for each color
plcol0(grey); # text is written in grey
plptex ( xt, yt, 0, 0, 0, text);
endfunction
As i set width in legend, i need to set it again in the main loop.
Also i need to pass (xmin xmax ymin ymax) as i dont know how
to just say draw at x = 10% of window ....
ideally i would like to have just :
legend (num, text)
and all other informations from some plgxyz inside legend function.
I hope my explainations are clear enought this time :)
Alain
PS: i m on the list, thanks for CCing me, buts it is not needed.
