This basically comes down to inserting additional line breaks in your
data file. It's explained in more detail in "help data" but the extra
line break creates a discontinuity. To get a plot like the one above, you
will group all the points with the same y-coordinate together and insert
an extra line break between each group of shared-y-coordinate points.

There are some demos that are somewhat related:

How shall I know whether I am the "intended recipient(s)"?
These sorts of disclaimers are irritating, unenforceable, and probably
harmful to any possible legal action based on the affected email
(because, among other reasons, it's almost certainly not consistently or
universally enforced). There used to be an excellent website explaining
how/why in detail, but I can't find it anymore.

Hi.

Thanks for the advice.  Does the "every" command work when you have two line beaks between data sets?  I can't seem to get it to work.

Regarding the legal disclaimer.  I have no control over it I am afraid.

Thanks

Adrian
