Plotting two files into one plot with different rows in two files

Show all headers | View raw

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 need to plot this line also onto the standard's plot.  

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 denominator" method, expanding both File A and B into 365 rows and plot?  I think this is too clumsy.  

Any elegant method?


Thanks in advance.

Steven.
