Hi Frank, > I'm trying to create a two-dimensional display of some mass-spectrometry > results (observed and theoretical). For my particular work right now, that > means I'd like to create the following for each data point (x,y): > > 1. a vertical line that runs from (x,0) up to (x,y) > 2. a point somewhere along that vertical line (probably at the > top), indicating the mean value of the signal y for that x-value. > 3. two (or more) horizontal bars, one above the mean point, one > below, to indicate some kind of statistics (standard deviation, percentile > score, ... - basically some kind of error bar) > > From Ugo's excellent tutorial, I can see how to put in the point (in 2. > above) along with the lines. However, it's not clear how I can put in the > vertical lines. I guess I can fulfill 1. and 3. by using subs.drawLine() > function to draw the lines item by item. I'm just wondering if there isn't > a more "built-in" way of doing this for the set as a whole. See Ugo's message about making bar graphs at: http://www.unidata.ucar.edu/glimpse/visad-list/1107 You may be able to translate this logic into VisAD-Python. > Also, if I wanted to use a symbol for the point-markers in 2., is there any > way for me to do that? Instead of just a dot, could I put in a 'star' (*), > a cross (+) or some other textual symbol easily? The Shape logic may help you do this. This logic is accessible from VisAD-Python as described at: http://www.unidata.ucar.edu/glimpse/visad-list/3183 Good luck, Bill ---------------------------------------------------------- Bill Hibbard, SSEC, 1225 W.
