Not exactly like you seem to imply (apply a user configurable formular to cursor readout). But there is a workaround: You can configure a derivative graph that applies some math magic to the raw data. The cursor will show the value of this second graph like any other. > Custom gridlines?

My data sets typically comprised 1^6 points. Does this qualify as "thousends and thousends"? Anyway, I didn't test how large the data files could get. > Can it read out one or two waveforms out of a file that may have > thousands? No. I'd use a trivial awk scrip to single out the desired waveform. >> Any reason to reinvent the wheel? > > We'd like a round one? xmgrace is open source. If the offending edges are small, it may be a lot easier to fix the issue in place than to breed a whole new app. ---<(kaimartin)>--- -- Kai-Martin Knaak http://lilalaser.de/blog _______________________________________________ geda-user mailing list geda-user@moria.seul.org http://www.seul.org/cgi-bin/mailman/listinfo/geda-user
