Thanks, I'd see the DATE TiME thing in the source but had not found out 
how to set it. Looks just the ticket.

Perhaps the current default is not the most logical choice. I would have 
thought that what has been chosen for the graph would be the obvious 
default for the label and the live coord read out , both in interactive 
and js context.

In this case I have
set timefmt  "%H:%M:%S"
set format x "%02Hh%02M"

Now timefmt is what is required by the *input* data , not the graph 
output. Never the less this is what is provided with an integer arg of 3

Similarly an argument of 5 will get me a simple hh:mm format which  may 
or may not be the same as my displayed x coord. In this case not.

help states:

  The following formats are available:

   0   default (same as 1)
   1   axis coordinates                    1.23, 2.45


This is wrong. Neither 0 nor 1 display what I have on the axis 
coordinates . In fact if I select "1" I get a decidedly unhelpful 
15032.4 instead of a legible time coord.

I would suggest that if xdata = time then mouse should be using this.
If format x is set this should be used rather than timefmt (which is the 
default x format, not the actual one).

In summary default mouse format should be what is displayed on the 
graph, taking into account any setting used in created it.

In an interactive terminal, I guess any later changes to format 
specifiers would change mouse behaviour. That is up to the use.


Perhaps this is what was originally intended since it seems odd having 
both 0 and 1 do the same.





Thanks for your help. I think this should do just what I want with an 
explicit option rather than the default.

Best regards, Peter.
