This is precisely what I normally understand by "nonogram". Hence I was initially puzzled by ding ding's original query, asking about "a nomogram for bladder cancer". This got me googling, and I found the sort of thing you can try out at http://www.nomogram.org They call this sort of interface "nomogram" too, and you can have a go at the one they offer for bladder cancer. This is not a graphical nomogram in the sense that you describe, rather it is a form-filling interface with boxes into which you insert information, and then press the button. Hence my question, in my original response, to ding ding as to whether this was the sort of thing he means (rather than the graphical one). Until we hear further from him about what he precisely means, I don't think it it worth while anyone spending effort on chasing solutions to what may be the wrong interpretation (either the graphical or the form -- we don't know). > Is there any program in R, S, C, Fortran, etc to compute such > a graph.

The few I have made in my time were not done quickly, nor did they come out well first time (nor second ... ). I've always constructed such things "by hand" (good layout is very impotant), with computer support for computation of relevant numerical values. So I can't suggest general-purpose nomogram generating software (and I doubt it would work well in many cases).
