[Gnuplot-info] Connect points if with some are missing

[Nikolaus R. <Nik...@ra...>]

Hello,

My datafile looks like this:

----snip----
0       100     100     100     -       -
1       92      100     95      -       -
5       149     77      -       -       -
10      86      82      71      113     79
20      85      64      -       88      73
30      84      61      -       84      70
50      106     55      37      82      58
100     77      13      -       99      25

Now I want to make a plot containing 5 graphs, one for each column. I
tried this with:

set datafile missing "-"
plot "plot1.csv" using 1:2 title "MTT" with lp, \
     "" using 1:3 title "OD" with lp,  \
     "" using 1:4 title "Cell Count" with lp, \
     "" using 1:5 title "MTT with catalase" with lp, \
     "" using 1:6 title "OD with catalase" with lp

but unfortunately the datapoints in the fourth column are not
connected, I suspect because of the missing ones in between. Is there
a way to get a continous graph?


And when I'm already asking: Is there some way to stretch the entire
plot so that the difference between 0 and 1 becomes more visible? I
tried logscale, but this doesn't work for x=0..

Thanks in advance,
