Hi, using a recent cvs build on Ubuntu: Create a series with all NA's. First glitch: Try to plot a boxplot, the error message says (slightly misleading IMHO): "series is a constant" Second glitch: Interpret data as time and series, and trying to do a time series plot produces the following errors on the console: <console output> realgen: exiting on lex() error 15 gnuplot: using pngcairo driver stderr: ' set xrange [1.797693135e+308:1.797693135e+308] ^ "/home/svenne/.gretl/gpttmp.OjFw46", line 18: undefined value ' gretl_errmsg: ' set xrange [1.797693135e+308:1.797693135e+308] ^ "/home/svenne/.gretl/gpttmp.OjFw46", line 18: undefined value ' Failed command: 'gnuplot "/home/svenne/.gretl/gpttmp.OjFw46"' </console output> thanks, sven
