I am using gnuplot 5.0 patchlevel 3 and trying to plot a filledcurved generated from a data file. The data file is previously filtered and sorted with the help of awk and sort. A minimal script is
set style fill transparent solid 0.2
plot "<awk -f awkfile filename|sort -g -k 1" u 1:2 with filledcurve y1=90,'' u 1:2 w points
The output fills the curve up to y1=90, which is fine. However every data point is stick with a vertical line runnning from y to y1=90. The line is solid and non-transparent. It ruins the output. How can I get rid of them?
