Hi everyone I need to create a graph showing pairs of value. One item from each pair is a single value, the other one is supposed to show a range of values (my idea was to plot the mean value with error bars to indicate the range's max and min, but I'm open to better ideas). The xaxis has no purpose other than giving the names of the various categories (just like in a histogram)  all that matters are the yvalues. I am pretty sure I could create something like this (value pairs and xcategories) using histograms, but boxes just strike me as wrong in this case. Is there a way to create such a graph? If so, could you please point me in the right direction? Thanks a lot for your time! PS: I have already asked this question on stackoverflow, but I guess it's not really the right forum for gnuplot questions. There, however, I have also included a rough sketch of my desired graph, and some further details.

hi, Maybe boxerror is what you are looking for ? here is a small demo. re wh set xrange [1:5] set yrange [0:10] set boxwidth 1 plot "" u 0:1:2 with boxerror 5 0.5 7 0.5 5 0.7 e Am 04.12.2011 17:27, schrieb canavanin: > > Hi everyone > > I need to create a graph showing pairs of value.

Dear Walter Thank you very much for your quick reply. The trouble is that I would prefer not to use boxes at all, certainly not for the single values I have to plot. I think the plot would be much clearer if I used points (and maybe error bars or lines) only. Thanks again!
