plotting csv data with some empty regions

Show all headers | View raw

I was hoping to do a line plot for some time-domain data that looks something like this:

1,,
3,,
4,,
2,,
3,,
4,1,5
2,2,7
3,1,
2,1,
5,,

With:
plot 'stuff.csv' with lines

I get the first column fine.

Let's try:
plot 'stuff.csv' using 1:3 with lines
                                ^
         warning: Skipping data file with no valid points
                                                   ^
         x range is invalid


I am hoping for something that will start plotting the other lines when they become relevant, and stops plotting them as their data regions go stale again.  Is this readily possible?  I had pondered just popping in zeroes, but in the expanded set this becomes horrific to read; the chops when it transitions to/from zero make the plots useless.
