Hi, I was trying to use the boxplot tool (Graph/Display Data) from within our local Galaxy instance (just updated yesterday). I faced a couple of issues while trying to generate boxplots. I was wondering which gnuplot version is actually recommended? While working with gnuplot version "4.0 patchlevel 0", one of the error messages was: line 0: undefined variable: tmargin gnuplot> plot '/tools/galaxy/database/files/000/dataset_94.dat' using 1:7:11:12:9 with candlesticks lt 1 lw 1 title 'Quartiles' whiskerbars, '' using 1:8:8:8:8 with candlesticks lt -1 lw 2 title 'Medians', "< python -c \"for xval, yvals in [ ( fields[1 - 1], fields[13 - 1].split( ',' ) ) for fields in [ line.rstrip( '\\n\\r' ).split( '\\t' ) for line in open( '/tools/galaxy/database/files/000/dataset_94.dat' ) if not line.startswith( '#' ) ] if len( fields ) > max( 1 - 1, 13 - 1 ) ]: print '\\n'.join( [ '%s\\t%s' % ( xval, yval ) for yval in yvals if yval ] )\"" using 1:2 with points pt 29 title 'Outliers' ^ line 0: ';' expected this can be overcome this by deleting "tmargin" form the "boxplot.xml" file. The second error message: gnuplot> plot '/tools/galaxy/database/files/000/dataset_94.dat' using 1:7:11:12:9 with candlesticks lt 1 lw 1 title 'Quartiles' whiskerbars, '' using 1:8:8:8:8 with candlesticks lt -1 lw 2 title 'Medians', "< python -c \"for xval, yvals in [ ( fields[1 - 1], fields[13 - 1].split( ',' ) ) for fields in [ line.rstrip( '\\n\\r' ).split( '\\t' ) for line in open( '/tools/galaxy/database/files/000/dataset_94.dat' ) if not line.startswith( '#' ) ] if len( fields ) > max( 1 - 1, 13 - 1 ) ]: print '\\n'.join( [ '%s\\t%s' % ( xval, yval ) for yval in yvals if yval ] )\"" using 1:2 with points pt 29 title 'Outliers' ^ line 0: ';' expected Again, I just removed "whiskerbars" and I got my plot... After getting updated my gnuplot (version 4.4), those issues were solved but there was another one related to the fonts, message: "Could not find/open font when opening font "arial", using internal non-scalable font" This could also be "fixed" by setting explicitly the font in the boxplot.xml (according to what I was just told, arial is proprietary and in some linux systems could represent an issue...): For instance: set term png size ${graph_size} font "/usr/share/fonts/liberation/LiberationSans-Regular.ttf,12" anyway, is there any gnuplot version recommended? Could the boxplot.xml be fixed/adapted to cope with those issues? cheers, Erick
