plot traveltimes axes configuration

Hello, i have some seismic survey data (7 channels) and tried to plot them all in one figure without axes. So far so good but I want all 7 subplots to have one common x-axis and one common y axis. Any ideas?

My code is the following

clear all

load('G1.txt')
load('G2.txt')
load('G3.txt')
load('G4.txt')
load('G5.txt')
load('G6.txt')
load('G7.txt')
L=length(G1);
Fs=2048;
t=(L/1000) - 0.0001;
tvect = (0:0.001:t)';
figure
subplot (1,7,1)
plot (G1,tvect,'k')
hold on
ylim ([0 2])
haxes = gca;
axis off
set(gca,'Ydir','reverse')
subplot (1,7,2)
plot (G2,tvect,'k')
hold on
ylim ([0 2])
haxes = gca;
axis off
set(gca,'Ydir','reverse')
subplot (1,7,3)
plot (G3,tvect,'k')
hold on
ylim ([0 2])
haxes = gca;
axis off
set(gca,'Ydir','reverse')
subplot (1,7,4)
plot (G4,tvect,'k')
hold on
ylim ([0 2])
haxes = gca;
axis off
set(gca,'Ydir','reverse')
subplot (1,7,5)
plot (G5,tvect,'k')
hold on
ylim ([0 2])
haxes = gca;
axis off
set(gca,'Ydir','reverse')
subplot (1,7,6)
plot (G6,tvect,'k')
hold on
ylim ([0 2])
haxes = gca;
axis off
set(gca,'Ydir','reverse')
subplot (1,7,7)
plot (G7,tvect,'k')
hold on
ylim ([0 2])
haxes = gca;
axis off
set(gca,'Ydir','reverse')

I'd give you some guidance but I don't understand what you mean.

"Hello, i have some seismic survey data (7 channels) and tried to plot them all in one figure without axes (as seen in picture1)."

without axes? There are seven axes in picture 1.

"So far so good but I want all 7 subplots to have one common x-axis and one common y axis (as seen in picture 2). Any ideas?"

What do you mean common axes? Do you want them plotted in the same axes or different axes that happen to share the same ylimits? I don't see how the plots in the second picture share x-axes. They are clearly plotted on separate x-axes and then you've added some line with labels on top.

If I had to guess, you want 7 axes with 6 hidden y-axis so that it appears as if they're plotted on a single axes. Then you want 7 different x-axes with the same limits, and perhaps you want to hide those xaxis. Finally, you want labels on each curve. Correct?

Exactly!

Try this. You can set 'xtick' to [], if you want to retain only the labels.

out = load('tvect.mat');
tvect = out.tvect;
for i=1:7
    out = load(sprintf('G%g.mat',i));
    data.(sprintf('G%g',i)) = out.(sprintf('G%g',i));
end

figure;hold on
for i=1:7
    ax(i) = subplot(1,7,i,'ycolor','none','color','none',...
        'xaxislocation','top');hold on
    plot(data.(sprintf('G%g',i)),tvect);
    xl(i) = xlabel(sprintf('G%g',i));
   set(xl(i),'position',xl(i).Position)
   text(0,0,sprintf('G%g',i),'horizontalalignment','center')
end
set(ax(1),'ycolor','k')

linkaxes(ax,'xy')
ylim([0 2])

Yes but instead of plot(rand(10,1)) i want to plot(G1,tvect) then plot(G2,tvect)....plot(G7,tvect)

This was just an example. The problem with plotting your variables in a loop is that you are using indexed variable names, which is a big nono. What you can do is load the .mat file into structs and then call the data using dynamic field variables. If you upload 2-3 of your mat files I will help you.

Okidoki, I've updated the answer.

Jonas thank you very much for your time and your help! That was exactly what i wanted!

My pleasure!
