I wanted to change the linecolour for half of the datapoints in a
column of data but I can't work out if this is possible?
If the line data is in one column like this (using comma as delimiter)
(first two columns are histogram):
"xlabel1",45,10
"xlabel2",67,10
I suppose I'd need to do something like this:
plot "file.csv" using 2:xticlabels(1) linecolor rgb 'blue' title
"Response Time",\
[0:50] '' using 0:3 with lines linewidth 3 linecolor rgb 'red'
title "Median Response Time (points 1-50)",\
[51:100] '' using 0:3 with lines linewidth 3 linecolor rgb
'green' title "Median Response Time (points 51-100)"
but of course this is all illegal syntax because ranges apply to the
whole plot and have to be the first argument to plot. Also, I don't
know how to start the x coord at anything other than 0 and have it
autoincrement as with the special "0" value.
I ended up having to split the median column into two columns like
this:
"xlabel1",45,10,
"xlabel2",45,10,
..
..
..
"xlabel50",45,10,
"xlabel51",67,,10
..
..
..
and then plot with
plot "file.csv" using 2:xticlabels(1) linecolor rgb 'blue' title
"Response Time",\
'' using 0:3 with lines linewidth 3 linecolor rgb 'red' title
"Median Response Time (points 1-50)",\
'' using 0:4 with lines linewidth 3 linecolor rgb 'green' title
"Median Response Time (points 51-100)"
Any ideas on how I could do this without messing about with the data
file? I can't use separate plot commands as of course that just
overwrites the previous plot. And multiplot doesn't work because the
first part of the plot is a histogram with words as xticlabels so the
second multiplot doesn't line up at all with the first one.
