[Gnuplot-info] Plot questions

[joachim h. <jh...@jo...>]

Hello -

I'm new in gnuplot. I wrote a script which reads single lines with the  
"every" option. This works well, but I have two questions:
1) I'd love to have the value which is written in column 1 (which is a  
time in my case) as the legend (key). Is this possible?
2) I have several xy-pairs in a line. I plot them with
	"myfile.txt" every ::1::1 using 3:2 with imp,\
	"" every ::1::1 using 6:5 with imp notitle,\
	"" every ::1::1 using 9:8 with imp notitle,\
and so on. Can I change the colors in a way that the first xy-pair  
(using 3:2 in the example above) is in red colour, and then the color  
circle is crossed so that the last value is blue? (There are different  
numbers of pairs; sometimes 6 or 12 or whatever. In each case the  
first xy-value should be red and the last blue.)

Thanks for any help. Best regards -
