Hi, have you designed such type of graph. If yes then kindly share the ideas how you designed it. Because we have to make such graph for best washer under 500. So that we could easily flot the data for our customers.

The format of the time in the data file must be specified in the style of

set xdata time
set timefmt "%d%m%y"
set format x "%B"  # "%b" seems to be broken
plot "datafile" using 1:4 notitle
