Hi forum--

I am trying to plot multiple histograms, but I want them all to have the same yrange so that the bars are visually comparable across plots. BUT, I also want gnuplot to auto-range the y axis. I don't mind plotting in two passes (plot all, capture max yrange, replot all). But I don't know how to query the value of the yrange into a variable. I know about 'show yrange'. But I don't know how to use that information. I could script around gnuplot (ie, Ruby), but if I'm going to do that, I just as well write my own bucketizer in Ruby to determine the max height of buckets across my datasets.

Since gnuplot is not a general programming language, I think this may be too tall of an order. Sure would be cool if it were a full language (or re-built on top of an existing one).

Thanks!
