#4524 — plotting text

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
