plot - How do gnuplot margins work in multiplot mode? -


i bit confused gnuplot margins. first of have no idea units these things pointing to. pointing canvas coordinates or fraction of canvas coordinates. behave same in gnuplot mode , multiplot mode?

my problem arises when plotting data in multiplot mode. plotting screen (wtx terminal). let's bungling things badly - plots off canvas, or small unreadable plots.

without margins first plot flush against top of canvas, naturally want push down bit.

can explain how gnuplot margins work , if behave same in multiplot mode.

yes, margins behave similar in "normal" plotting mode , in multiplot mode. basically, margins can have 3 different "modes":

  1. automatic, default.
  2. setting each margin specific size, set lmargin 2. unit character widths (or character heights tmargin , bmargin).
  3. setting specific position of border relative whole canvas, set lmargin @ screen 0.1, sets left plot border @ 10% of total canvas width.

the difference of multiplot mode is, reference margins in 1. , 2. given sites determined layout option:

set multiplot layout 2,2

this subdivides whole canvas in 4 rectangles of equal size. now, using

set lmargin 1 set rmargin 1 set tmargin 1 set bmargin 1

leaves margin of 1 character width or height on each side of each subplot respect smaller rectangles:

set multiplot layout 2,2 set lmargin 0 set rmargin 0 set tmargin 0 set bmargin 0 set format '' plot x plot x**2 plot x**3 plot x**4 unset multiplot

enter image description here

set multiplot layout 2,2 set lmargin 1 set rmargin 1 set tmargin 1 set bmargin 1 set format '' plot x plot x**2 plot x**3 plot x**4 unset multiplot

enter image description here

if want set absolute positions of each border, becomes more cumbersome, because have set 4 margins each plot (the layout options doesn't have effect in case):

set multiplot set lmargin @ screen 0.1 set rmargin @ screen 0.47 set tmargin @ screen 0.97 set bmargin @ screen 0.6 plot x ...

gnuplot version 5 offers quite flexible way produce equal rectangles, see answer removing blank gap in gnuplot multiplot

How to group boxplot outliers in gnuplot -

i have large set of data points. try plot them boxplot, of outliers exact same value , represented on line beside each other. found how set horizontal distance between outliers in gnuplot boxplot , doesn't much, apparently not possible. is possible group outliers together, print 1 point , print number in brackets beside indicate how many points there are? think make more readable in graph. for information, have 3 boxplots 1 x value , times 6 in 1 graph. using gnuplot 5 , played around pointsize, doesn't reduce distance anymore. hope can help! edit: set terminal pdf set output 'dat.pdf' file0 = 'dat1.dat' file1 = 'dat2.dat' file2 = 'dat3.dat' set pointsize 0.2 set notitle set xlabel 'x' set ylabel 'y' header = system('head -1 '.file0); n = words(header) set xtics ('' 1) set [i=1:n] xtics add (word(header, i) i) set style data boxplot plot file0 using (1-0.25):1:(0.2) boxplot lw 2 lc rgb '#8b0000...

bash - Performing variable substitution in a string -

i have string contains use of variable, , i'd substitute variable's value string. right best have is #!/bin/bash foo='$name; echo bar' name="the name" expanded="$(eval echo "$foo")" echo "$expanded" which has obvious defects: prints the name bar while i'd print the name; echo bar instead of eval can bash's regex matching bash's string replacement: foo='$name; echo bar' name="the name" [[ "$foo" =~ \$([[:alnum:]]+) ]] && s="${!bash_rematch[1]}" && expanded="${foo/\$${bash_rematch[1]}/$s}" echo "$expanded" name; echo bar
