xtics label with conditions using gnuplot

Question

I am interested in labeling the xtics with strings from a column in a file. The file is written in the following manner:

Index Name Status Value
1 Ver1 with 0.3
2 Ver1 without 0.25
3 Ver2 with 0.35
4 Ver3 with 0.27

The datas shall be plotted with a conditioned plot

plot file u (strcol(3) eq "with"?$1:1/0):($4) w p pt 7 notitle

The xtics shall be labeled with the data contained in column(2). If all values are used this can be done by xticlabel(2). But I only want to use the filtered data to get a plot like:

|
|     x      x     x
|     
----------------------------
    ver1   ver2   ver3

The questions is: How can I label the xtics using only the filtered values?

Thanks in advance!

You could impose the same condition in xticlabel as well, i.e., to use column 2 if required or pass an undefined value instead:

plot 'file.dat' u \
  (strcol(3) eq "with"?$1:1/0):4:xticlabel((strcol(3) eq "with")?strcol(2):1/0) \
  w p pt 7 notitle
