How do I place a point anywhere along x axis (with range 100m) in a plot?

Assuming I have a plot with x axis ranging from 0 to 100meters.
How do I place a point 'k' indicating 53m on the x axis?

x0 = 53;
y0 = 0;
plot(x0,y0,'o')
ylim([0 1])
xlim([0 100])

If you want the marker to stay on the x axis even if the y-limit changes, you can use the LimitsChangedFcn to update the y-coordinates of the point any time the axis limits change.

Highly confusing. Do you want to plot a single point? What y value? Maybe you want to do this?
k = 53;
plot(k,0,'ro') % A single point at x==k==53
xlim([0,100])
Or, maybe you want this?
figure
xlim([0,100])
xline(k,'r') % A vertical line
Do you just want to display a horizontal number line? So no y axis at all?
plot(k,0,'ro') % A single point at x==k==53
xlim([0,100])
H = get(gca);
H.YAxis.Visible = 'off';
I could probably do better than that. But I have no idea what you are looking to see. Again, a confusing question.
