I have a column of data which contains values from 0 to 6 which I want
to control the historgram bars - any ideas? I tried this
plot 'foo' using (($4 == 0) ? $2 ? NaN):xticlabels(1) linecolor
'somecolor',\
'' using (($4 == 1) ? $2 ? NaN):xticlabels(1) linecolor
'someothercolor'
but of course gnuplot sees these two clauses as seperate histogram bar
clusters which is not what I want at all ... there is only one dataset
but I want to color the bars depending on a data value in the fourth
column ...
