How to eliminate gap between tile charts

Hey guys,
I am trying to create a graph with 3 sections, each with a different x axis but the y axis is the same throughout. I used tile chart layout learnt from and set TileSpacing = 'none', but there is still a gap between the sections as shown in the picture. How do you eliminate the gaps between the sections?
x = 0:0.1:60;
y1 = 4.*cos(x)./(x+2);
y2 = 5*sin(x)+0.5
t = tiledlayout(1,3,'TileSpacing','none'); %no tile spacing?
bgAx = axes(t,'XTick',[],'Ytick',[],'Box','off');
bgAx.Layout.TileSpan = [1 3];
%plot part 1
ax1 = axes(t);
ax1.Box = 'off';
xlim(ax1,[0 15])
xlabel(ax1,'First Interval')
%plot part 2
ax2 = axes(t);
ax2.Layout.Tile = 2
ax2.YAxis.Visible = 'off';
ax2.Box = 'off';
xlim(ax2,[15 45])
xlabel(ax2, 'Second Interval')
%plot part 3
ax3 = axes(t);
ax3.Layout.Tile = 3
ax3.YAxis.Visible = 'off';
ax3.Box = 'off';
xlim(ax3,[50 60])
xlabel(ax3, 'Third Interval')
%link axes
linkaxes([ax1 ax2 ax3],'y')

I'm running R2021a. Clearly, Adam's answer is spot on. Good luck.

Update to Matlab R2021a to take advantage of the new tile spacing when TileSpacing is set to none.
The only other way to set juxtaposed axes is by setting axes position manually this template:
nAxes = 3;
axXPos = linspace(0.05, .95, nAxes+1); % For axes that span 0.05 to 0.95 horizontally
axXPos(end) = [];
axWidth = axXPos(2) - axXPos(1);
ax = gobjects(size(axXPos));
for i =1:numel(axXPos)
ax(i) = axes('Units','Normalized','Position',[axXPos(i),.2,axWidth,.4]);
box(ax(i), 'on')
set(ax(2:end),'YTickLabel', {})
linkaxes(ax,'y') % If you want to use the same y-ticks for all axes
To turn off y-axis lines,
ax(i).YAxis.Visible = 'off';

TileSpacing works differently in versions prior to R2021a. The link I provided explains that.
TileSpacing=none in releases prior to R2021a is the same as TileSpacing=Tight in Matlab R2021a+ and "none" was redfined as having no space between axes.
