Hello,

I browsed all topics about plotting two files into one plot.  None of them =
mentioned with different rows problems.  The scenario I met is as follows:

File A is babies standard growth file, which show babies growth chart based=
 on history data, like 95%, 90%, 75%, 50%, 25%, 10%, and 5%.  In this data =
file there are only a 5 rows (born, 3 month, 6 month, 9 month and 12 month)=
 with 8 columns (month + 7 Y values).

File B is what parents input.  The times they input can be any dates in the=
 first year (365 possibilities) due to their various measuring time.  I nee=
d to plot this line also onto the standard's plot. =20

The current code is:

plot "A.dat" using 1:2 title '95%' with lines 1, \
     "" using 1:3 title '90%' with lines 2, \
     "" using 1:4 title '75%' with lines 3, \
     "" using 1:5 title '50%' with lines 4, \
     "" using 1:6 title '25%' with lines 5, \
     "" using 1:7 title '10%' with lines 6, \
     "" using 1:8 title '5%' with lines 7, \
     "B.dat" using 1:2 title 'your baby' with points 3

But this require rows of A is the same as rows of B.

How to handle the problems like this.  Do I have to use "least common denom=
inator" method, expanding both File A and B into 365 rows and plot?  I thin=
k this is too clumsy. =20

Any elegant method?


Thanks in advance.

Steven.
