try this: y1=y2=y3=0 plot './eva.dat1' using 1:(strstrt(stringcolumn(4),"5000-1FE1-5000-BDDC") ?(y1=$2+$3,y1) : y1) with linespoints title "ARRAY01/B/1",''using 1:(strstrt(stringcolumn(4),"5000-1FE1-5000-BDDD") ?(y2=$2+$3,y2) : y2) with linespoints title "ARRAY01/B/2",'' using 1:(strstrt(stringcolumn(4),"5000-1FE1-5000-BDDE") ?(y3=$2+$3,y3) : y3) with linespoints title "ARRAY01/B/3" explanation: stringcolumn(.) == "string" doesn't work, but strstr(stringcolumn(.),"string") does. using 'NaN' sets the datapoint to 'undefined' and this interrupts the plot - this way you don't get lines between the points. so it's better to just plot the last valid point again. (and omit the 'multiplot', you don't need it for a single plot.) mbm329 wrote: > > Hello, > > I'm trying to plot read and write requests from a storage array.
