Hmm, no. It's entirely possible to modify timeplot to allow the painting function to be pluggable but right now it's not, it's fixed. I could be convinced to do that but I would need at least 3 different people asking for it and with a substantial need for it... and without negatively impacting the existing user base. > 2.

With the above you could do the line painting in any way you like. > For example, Napoleon's Russian Campaign by Count Philippe-Paul de Ségur has > the x-coordinate represent both time and location (Paris to Moscow).

Uh, aiming pretty high there, aren't you ;-) (that plot is considered by Tufte the best plot ever). The problem of plotting a (t,v1,v2) time series is, IMO, radically different than plotting a (t,v) time series, unless, of course, one could write the time series as (t,v,f(v)) which Timeplot already supports. The use of color coding or shape coding for v2 is a good suggestion but I fear the complexity of going down that path (for example, one could expect (t,v1,v2) to become (t,v1,f(v1),v2,g(v2)) and so on. Color coding on such a thin line is probably not the best solution and shape coding could be perceived either as a visual artifact for small values or as very distorting for bigger values. I don't know, I'm not entirely against it but right now I fail to see real value for it. Can you elaborate more on a few practical scenarios where you would like to use this? -- Stefano Mazzocchi Digital Libraries Research Group Research Scientist Massachusetts Institute of Technology E25-131, 77 Massachusetts Ave skype: stefanomazzocchi Cambridge, MA 02139-4307, USA email: stefanom at mit . edu ------------------------------------------------------------------- _______________________________________________ General mailing list [email protected] http://simile.mit.edu/mailman/listinfo/general
