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!

在 MATLAB Online 中打开

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])
