How to create several figures in a subplot with different axes?

Dear all,

I'm trying to create a subplot with 7lines and 1 column that plot all of my results consecutivelly.

I have this piece of code:

subplot(7,1,k);
    ax1=axes;
    imagesc(ax1,Xv,Yv,M);
    set(gca,'YDir','normal');
    h=colorbar;
    ylabel(h,'TOTAL Sound Pressure Level (dB)');
    clear title
    title(strcat('SPL Broadband\_', listofpercentis(k)));
    xlabel('LONGITUDE');
    ylabel('LATITUDE');
    axis tight;
    clear title
    ax2=axes;
    contourf(ax2,lon_km,lat_km,elevation', [0 0]);
    linkaxes([ax1,ax2]);
    ax2.Visible = 'off';
    ax2.XTick = [];
    ax2.YTick = [];
    set([ax1,ax2],'Position',[.17 .11 .685 .815]);
    ax2.Visible = 'on';
    ax2.Visible = 'off';
    cb1 = colorbar(ax1,'Position',[.865 .112 .04 .815]);
    ylabel(cb1, 'SPL (dB)','FontSize',12);
    %AUTOMATIC WAY
    % xlim([ax1,ax2],[xmin xmax]);
    % ylim([ax1,ax2],[ymin ymax]);
    axes(ax1); axis equal;
    axes(ax2); axis equal;
    hold on;
    %plot(km2deg(Sx),km2deg(Sy), '*k')
    %plot(-9,37.96, 'Ok');
    %source=text(deg2km(-8.99),deg2km(37.94),'source','FontSize',12)
    portugal=text(deg2km(-8.65),deg2km(37.86),'Portugal','FontSize',20);
    set(portugal,'Rotation',90);
    sines=text(deg2km(-8.869),deg2km(37.96),'*Sines','FontSize',14);
    caxis(ax1,[0 200]);

The problem is that all plots are displayed in the same position and I want to display the first plot in the first line, the second plot in the second line, etc etc.

You're aren't using subplot correctly. For each plot you need a separate call to subplot with the index (in your case, row) where you want the plot to appear:

subplot(7,1,1);
plot ... % something in the 1st row
subplot(7,1,2);
plot ... % something in the 2nd row
subplot(7,1,3);
plot ... % something in the 3rd row
...

Type doc subplot in the MATLAB's command window for more explanation and examples
