I am plotting same plot as from here How to plot multiple y-axes?. But also i would like them to look like in the image below. With additional lines and tics, how can i do it?
As mentioned in the answer you linked, you can plot many plots on top of each other in the multiplot environment.
So, here you are plotting 6 plots on top of each other
plot 1, 2, 3 for the data/functions
plot 4, 5, 6 for the colored axes
and plot 6 as well for the key on top of everything
In order to get the same scale for the plot and the "external" axes I would recommend to store the ranges and step sizes in the variables y10,y11,y1d, ...., such that you have to change the values only at one location.

I have two small datafiles
one

and one

I try to plot those as a histogram with labels

'file2.dat' u 2: xtic(1) with histogram lc rgb "#004500" title "Labb", \
'' using 1:(\$2):(\$2) with labels notitle font ",10"
EOF
But the labels are way off

// GH
The histogram plotting style is implicitly using the pseudocolumn 0 (check help pseudocolumns) as x-coordinate. So, you have to place your label at column(0) or ($0) with some x-offset, e.g. ($0-0.15) in the one and other direction. And some offset in y-direction, e.g. via offset 0,0.7.

This is my attempt at making the xtics label color match the line color in a box plot in gnuplot:
$DATA << EOD

set xtics ("1" 1) textcolor rgb "red"
set xtics add ("2" 2) textcolor rgb "green"
set xtics add ("3" 3) textcolor rgb "blue"
plot $DATA using 1:2:1 with boxes linecolor variable
But it does not work:
Any idea? Thanks!
I'm not sure whether you can set xtics individually in different colors. So, the following solution sets the xtics as empty lines and you plot your xtics with labels with a certain offset. The disadvantage is that you have to set the y-position here: (0) with offset 0,-1. I hope there are better solutions.
Code:
### "xtic labels" in different colors
reset session
$Data << EOD
1 1
2 2
3 3
EOD
set linetype 1 lc "red"
set linetype 2 lc "green"
set linetype 3 lc "blue"
set key off
set boxwidth 0.5
set style fill solid 0.5
set xrange [0:4]
set yrange [0:4]
set format x "\n" # xtic label empty line
plot $Data u 1:2:1 w boxes lc var, \
'' u 1:(0):1:1 w labels tc var offset 0,-1
### end of code
Alternatively, you could use an offset relative to the graph:
plot $Data u 1:2:1 w boxes lc var, \
'' u 1:(0):1:1 w labels tc var offset 0, graph -0.05

I have a problem. Im trying to do a polar plot, the fact it's that i want to plot some theorical line as some experimental data in the plot. But the theorical line has a range different of the experimental data because i had to do it like that to had gnuplot paint it.
I have the following script:
####
reset
set encoding utf8
set size 1,1
set terminal epslatex
set output "direccionalidad.tex"
unset border
set polar
set angles degrees #set gnuplot on degrees instead of radians
set style line 10 lt 1 lc 0 lw 0.3
set grid polar 30 #set the grid to be displayed every 60 degrees
set grid ls 10
set trange[-90:90]

set xrange[-31:32]
set yrange[-30:30]
set xtics axis #disply the xtics on the axis instead of on the border
set ytics axis
set xtics scale 0 #"remove" the tics so that only the y tics are displayedj
set ytics (0, 6, 12) #make the ytics go from the center (0) to 6000 with incrment of 1000
unset ytics
set xtics ("5" 6, "15" 16.5, "30" 32)
# set the xtics only go from 0 to 6000 with increment of1000 but do not display anything. This has to be done otherwise the grid will not be displayed correctly.
set rtics (5,15,30)
set rtics format ' ' scale 0
set_label(x, text) = sprintf("set label '%s' at (32*cos(%f)), (32*sin(%f)) center", text, x, x) #this places a label on the outside
eval set_label(0, "0")
eval set_label(30, "30")

And here there are some examples of columns in the direccionalidaddatos.txt archive, the column in the middle it's just the angle in radians but it's usless cause i just want the angle in degrees so just ignore it ;):
-90 -1.570796327 0.1
-85 -1.483529864 0.2
-80 -1.396263402 0.4

-70 -1.221730476 1.1
-65 -1.134464014 1.7
-60 -1.047197551 2.5

And the result it is the image Polar plot
As you see in the image there are two branches that have no points, i want those branches to simply don't disappear cause they don't mean notihng in the graphic.So if anyone knows a form to made dissapear the branches, or to improve the script let me know hehe.
Thanks so much.
Can you just reduce the sampled range for the second plot component?
plot "direccionalidaddatos.txt" u 1:3 pointtype 7 ps 2 lt 1 lw 3 lc rgb 'blue' notitle ,\
[-52:45] '+' using 1:(f($1)) with lines dt '-' lc rgb 'blue' notitle
I have two files each is having five columns where 1st will be the x-axis in both the data.
I want to make a multiplot 2 2 in GNU with zero spacing.
I could manage many things but I am could not fix below problems:
1. How to place the figure at the center of the page i.e. equal left right margin? I set the left, right, top and bottom margin but it is not working.
2. How to number the figure. For example, Figure 1 1 should be numbered as (a), figure 1 2 should be numbered as (b) and so on.
3. How to put tick lable and tick mark on the plot 1 2 and 2 2 on right side of the plot?
4. how to create a common title at the bottom of the figure representing the X-axis.

I'm not sure, why this doesn't work. Could be a bug. As workaround you can give a third column in the using statement to indicate the lower boundary of the filled area:
plot ...,\
dataFileForecast using 1:4:(0) with filledcurves linestyle 3
This gives the output
The freezeWarning area is plotted correctly, if the yrange includes this region.
