Re: [Gnuplot-info] problem with legend in svg pie-chart

[David L. <da...@la...>]

Doing some more digging, I'm finding that the colors used for the key legend are 
not the colors used for the linetype definitions that are used to make the graph

I changed the lines to
set linetype 1 lc "purple" lw 5 pt 3 ps 3
set linetype 2 lc "green" lw 5 pt 3 ps 3
set linetype 3 lc "yellow" lw 5 pt 3 ps 3
set linetype 4 lc "blue" lw 5 pt 3 ps 3
set linetype 5 lc "orange" lw 5 pt 3 ps 3
set linetype 6 lc "red" lw 5 pt 3 ps 3
set linetype 7 lc "brown" lw 5 pt 3 ps 3
set linetype 8 lc "gold" lw 5 pt 3 ps 3
set linetype 9 lc "cyan" lw 5 pt 3 ps 3
set multiplot

plot for [i=4:6] "site_summary.data" u (x+column(0)*250):(y):(r):(360*(sum 
[col=4:(i-1)] column(col))/(sum [col=4:6] column(col))):(360*(sum [col=4:i] 
column(col))/(sum [col=4:6] column(col))):(i) title columnhead(i) with circles 
lc var

and while the pie segments are blue, orange, and red. the legend colors are 
brown, gold, gold

so why is the key showing different color codes than what was used to make the 
graphs

and why is color 8 used twice?
