this is very nice about gnuplot:

plot file using 1:($1>0?$2:1/0) with histeps lt -1 lw 1

The 1/0 is to be read as plot nothing. Can be nested, gives powerful options

If I have a CSV file with several columns of data running to thousands of lines, how would I plot a discontinuous line plot of data in column 2 dependent on a value in column 1? For example, I would only want to plot those data in column 2 if the corresponding line value in column 1 is greater/less than/equal to a given value.
