Second x-axis with non-uniform spacing

I have made a plot with two x-axes, however I am struggling to line up the x-axis.
I have some time series data (x), and an associated reading (y), each timestep/reading has an other metric (x1) associated with it.
I want to plot(x,y), and have x1 appear on a second x-axis.
The problem stems from the fact that the time step within my time series data is not constant.
I have attached some code/figure showcasing the problem, when the timestep is constant, the time series data and other metric line up perfectly.
When the timestep is non-uniform, they no longer line up.
Is there an elegant way to resolve this?
This is not a one-off plot, so I would prefer a more dynamic solution.
If you have any idea how to display the other metric besides a second x-axis, I'd be interested in that too.
close all
A = rand(100,1);
x1 = datetime('now') + minutes(1:100);
x2 = 101:200;
x3 = datetime('now');
for ii = 2:100
x3(ii) = x3(ii-1) + minutes(rand());
end
figure();
subplot(2,1,1)
plot(x1,A,'+r')
xlabel("Time with uniform spacing")
ylabel("Random reading")
axis tight
hAx(1)=gca;
hAx(2)=axes('Position',hAx(1).Position,'XAxisLocation','top','color','none');
hold(hAx(2),'on')
plot(x2,A,'b')
axis tight
xlabel("Other metric with uniform spacing")
subplot(2,1,2)
plot(x3,A,'+r')
