Re: Plotting exclusive values

by Thomas Sefzick :: Rate this Message:

you are plotting 'with filledcurves', that means that the space underneath the
curve down to the x-axis is filled.
if there is no curve, there is no filling, just white space.

to see that gnuplot behaves as expected plot 'with linespoints'

but if you want a connection between points over some undefined
points in between, then you need to filter your data outside gnuplot,
e.g.:

plot "< awk '{if (\$14 == 300) print NR \" \" \$0}' mem.log" using 1:7 linetype 1 title "foo" with filledcurves x1

Hi there

I have data logged from top-command like

13013 name 20 0 16396 12m 1640 R 99 0.1 0:01.20 ./large 200 200 3
13048 name 20 0 16396 10m 1640 R 99 0.1 0:01.20 ./large 300 300 3
13052 name 20 0 16396 11m 1640 R 99 0.1 0:01.20 ./large 300 300 3
13048 name 20 0 16396 15m 1644 R 100 0.1 0:07.20 ./large 300 300 3
13013 name 20 0 16396 17m 1640 R 99 0.1 0:01.20 ./large 200 200 3
13013 name 20 0 16396 10m 1640 R 99 0.1 0:01.20 ./large 200 200 3
13052 name 20 0 16396 11m 1644 R 100 0.1 0:07.20 ./large 300 300 3
13054 name 20 0 16396 11m 1644 R 100 0.1 0:07.20 ./large 300 300 3
13048 name 20 0 16396 15m 1652 R 100 0.1 0:22.20 ./large 300 300 3
13075 name 20 0 7208 4m 1576 R 97 0.0 0:02.90 ./large 500 500 0
13081 name 20 0 9168 6m 1616 R 96 0.0 0:02.88 ./large 500 500 0

and I want to plot the memory ($6) only for 200, 300 or 500 ($14) at a time.

I've tried starting with 300:

inp = "mem.log"
set xrange [0:]
plot inp using ($14==300 ? $6 : 1/0) linetype 1 title "foo" with filledcurves x1

but this plots the not 300 values as 0. I want all not 300 values unplotted in the 300-plot so that there won't be empty places. How to? Need to say instead of '1/0' in using 'don't plot this value'.

I hope you understand and can help me.

Regards
Stepp
