How to change axes in tiledlayout with different x and y axes

I have 3 data sets with 2 different x axes, which I like to plot as a stackedplot. As far as I understood, this is not possible for a stackedplot, as I always need the same x axes. So I used tiledlayout and ploted those 3 separetely. When I try to adjust the XLimits and YLimits I get errors.

This is what I did so far:

XAxislow = 400;
XAxishigh = 1800;

t=tiledlayout(3,1);
ax1 = nexttile;
    plot(wave_raman,spec_raman);
    ax1 = gca;
    ax1.Box = 'off';
    ax1.FontSize=11;
    ax1.LineWidth=1.2;
    ax1.XLimits = [XAxislow XAxishigh];
    ax1.YLimits= [0 400];
ax2 = nexttile;
    ln2 = plot(wave_gauss3*A3,spec_gauss3);
    ax2 = gca;
    ax2.Box = 'off'; 
    ax2.FontSize=11;
    ax2.LineWidth=1.2;
    ax2.XLimits = [XAxislow XAxishigh];
    ax2.AxesProperties.YLimits= [0 40];
ax3 = nexttile;
    ln3 = plot(wave_gauss4*A4,spec_gauss4); 
    ax3 = gca;
    ax3.Box = 'off'; 
    ax3.FontSize=11;
    ax3.LineWidth=1.2;
    ax3.XLimits = [XAxislow XAxishigh];
    ax3.AxesProperties.YLimits= [0 40];

 txt = xlabel(t,'Raman shift [cm^{-1}]');
 txt2 = ylabel(t,'Raman intensity');
 t.TileSpacing = 'tight'; %compact tight none
 t.Padding = 'compact'; %compact tight
 txt.FontSize = 12;
 txt.Color = 'black';
 txt2.FontSize = 12;
 txt2.Color = 'black';

In order to set the limits, use the following

 ax1.XLim = [XAxislow XAxishigh];
 ax1.YLim = [0 400];

instead of

 ax1.XLimits = [XAxislow XAxishigh];
 ax1.YLimits= [0 400];

Thanks. I got confused with the different commands for different functions. Your suggestions work well. Do you have another suggestion how to create a nice stackedplot with different x axes?
