plotting text

[Jan Schmidt]

Hi,

is there a way to plot a datafile with text and replace the text with numbers?

i.e. the datafile looks like

1684746646.005043 open standby 0.3
1684746646.045847 closed standby 0.2

and I want a line chart where I can see the movement from "open" to "closed" as a jump.

plot "datafile" u 1:2 replace("open",1), replace("closed",2) w l, "datafile" u 1:4 w l

1684746646.005043 open standby 0.7
1684746646.045847 closed standby 0.8

plot [0:1.0][0:2.0] 'file' u 4:(strcol(2) eq "open" ? 1.0:0.0) w histeps
