Drawing arrow between plots (table datas)

I use pfgplots to draw two sets of data, stored in .dat. Now I would like to automatically draw an arrow from one curve to the other, and only at the curves points. I tried to name the paths, but to no avail... Here is my minimum working example:



documentclass[11pt]standalone
usepackagetikz,pgfplots,filecontents
pgfplotssetcompat=newest
usepgfplotslibraryfillbetween
beginfilecontents*data1.dat
a b
1 1
2 1.2
3 1.5
endfilecontents*
beginfilecontents*data2.dat
a b
1 1.5
2 1.75
3 1.6
endfilecontents*

begindocument
begintikzpicture
%graphique
beginaxis
addplot[name path=c1,blue,thick,mark=*] plot table[x=a,y=b]data1.dat;
addplot[name path=c2,black,thick,mark=*] plot table[x=a,y=b]data2.dat;
%draw[red,->] (c1) -- (c2);

endaxis
endtikzpicture

enddocument


Which gives:
example output



I would like to get (automatically from data points):
desired output



To generate this last picture I defined each arrow separately, for example for the last arrow:
draw[red,-latex,thick,shorten >=0.1em] (3,1.5) -- (3,1.6);



I tryed to use the fillbetween package to name the paths, but I have not been able to use it so far. Could I get something like : draw[red,->] (c1) -- (c2); ?



Thanks a lot for your help!

Here is an alternative based on this nice answer. Its advantage is that it does not rely on the plot points having always the same distance. In fact, in your data set they don't, and that's the reason why in your answer the middle arrow is not vertical.



documentclass[11pt]standalone
usepackagetikz,pgfplots,filecontents
pgfplotssetcompat=newest
usepgfplotslibraryfillbetween
beginfilecontents*data1.dat
a b
1 1
2 1.2
3 1.5
endfilecontents*
beginfilecontents*data2.dat
a b
1 1.5
2 1.75
3 1.6
endfilecontents*

pgfplotsset
name nodes near coords/.style=
every node near coord/.append style=
name=#1-coordindex,
alias=#1-last,
,
,
name nodes near coords/.default=coordnode


begindocument

begintikzpicture

beginaxis[
nodes near coords=,nodes near coords style=anchor=center
]
addplot[blue,thick,mark=*, name nodes near coords=c]
table[x=a,y=b]data1.dat;
addplot+[black,thick,mark=*, name nodes near coords=d] table[x=a,y=b]data2.dat;
endaxis
foreach X in 0,...,2
draw[red,latex-latex] (c-X) -- (d-X);
endtikzpicture
enddocument

  • If you want the arrows to "touch" the plot marks, use nodes near coords style=anchor=center,inner sep=2pt instead of nodes near coords style=anchor=center.

However you'll notice a slight shift of my middle arrow. I think this comes from my data not being evenly distributed... Would you have any insight on this ?

        Thanks to this previous post, I came up with this solution.



        documentclass[11pt]standalone
        usepackagetikz,pgfplots
        pgfplotssetcompat=newest

        beginfilecontents*data1.dat
        a b
        1 1
        2 1.2
        3 1.5
        endfilecontents*
        beginfilecontents*data2.dat
        a b
        1 1.5
        2 1.75
        3 1.6
        endfilecontents*

        %reads data
        pgfplotstablereaddata1.datdataA %beware that "data1" would trigger an error => do not use numbers
        pgfplotstablegetrowsofdataA
        pgfmathtruncatemacroNpgfplotsretval-1 %get access to the number of points in data

        begindocument
        begintikzpicture
        %graphique
        beginaxis
        addplot[blue,thick,mark=*] plot table[x=a,y=b]data1.dat
        foreach i in 0,...,N coordinate [pos=i/N] (ai);
        addplot[black,thick,mark=*] plot table[x=a,y=b]data2.dat
        foreach i in 0,...,N coordinate [pos=i/N] (bi);
        endaxis
        foreach i in 0,...,N
        draw[red,-latex,thick,shorten >=0.1em] (ai) -- (bi);

        endtikzpicture

        enddocument


        Which gives:
        solution1



        However you'll notice a slight shift of my middle arrow. I think this comes from my data not being evenly distributed... Would you have any insight on this ?
