how to space overlapping labels in plot

Dear all,
I´m analyzing MRI data and need to plot the intensity values and behavioural scores of a single voxel from a sample of patients. To label the data points, I used the identifier for each patient.
However, even if I decrease the font size for the labels, they overlap for those data points in close spatial proximity. I have tried to get around this by modifying the plot box and data aspect ratio but haven´t solved the problem yet.
I´d really appreciate if someone in the forum could help me with this since I´m sure it will be a recurrent issue in the future.
Here´s the main code I used for the plot. You can find the plot attached.
x=Syl_FJ12_PERC_MODEL_TP1.beh_cov;
y=cell2mat(pa_int_fixed(:,2));
label=pa_int_fixed(:,1);
figure
plot(x,y, '.r','MarkerSize', 15)
text(x, y, label,'fontSize',8);
title ('VBM Sanity check'), ylabel('GM Intensity Peak Voxel (-36 15 -33) Temp_Pole_Mid_L'), xlabel ('Syl JK12 Perc Model')
Thanks in advance for your time,

If you want somebody to perhaps take a shot at it, attach a dataset that reproduces the problem.

many thanks for taking the time to reply. I thought that a way to solve this would be to programmatically modify the scaling of the axes so that these close data points would be more distant, as it happens when you zoom in on the area where they are located. But, as you pointed out, to do this programmatically is not trivial...
I´ll try to modify the location of the label for these data points either with text or annotation to make sure that they are legible.
best,
Noelia
