Sorry for the delay on getting back to you on this, but I think the problem is not so much with the Reader actor, but more likely with the DT domain.
Under Ptolemy II 1.0.1, your no_up_down_sample.xml file produces two
samples at x=1
Under our development version, the output looks much better. I'm not sure
where
the problem was fixed. I'll look into folding it in to the regression tests so
that we can see if the problem reappears.

I think I have found a problem with the Reader actor.
Attached are 3 simple files to illustrate the problem
no_up_down_sample.xml
contains a Reader straight into sink actors.
up_down_sample.xml
contains a Reader passed through a up-sample and down-sample
actor into sink actors.
sample2.txt
contains data used by both Readers
Note the behavior between samples 2 and 3 on the output display.
Why the entry of two values on sample 1 when there is no up/down sample?
The up/down sample fixes the problem so I have a work around.
Thank You
