Hi, the 'gnuplot' command in gretl can be tweaked by passing additional gnuplot options in curly braces, which is very useful (=saves a lot of time when producing a bunch of similar graphs). So I tried to do a similar thing with the 'freq' command, but --as expected-- that failed. OTOH, the doc for 'boxplot' says that these additional options should work there, too, so might I suggest that the curly-braces stuff could be enabled in all gnuplot-related commands? Then I wondered about how many different commands there are that involve graphing and gnuplot. This is the (probably incomplete) list I got: - gnuplot (option '--output=') - corrgm (option '--plot=') - freq (option '--show-plot') - pergm (option '--plot=') - xcorrgm (option '--plot=') (wasn't this made obsolete and rolled into corrgm?) - boxplot (option '--output=') - scatters (option '--output=') As you can see, I have written down the name of the options that control whether or not the plot is actually shown. This state of affairs seems to be a little inconsistent, I would suggest to harmonize the use of '--plot' and '--output' for gretl 2.0, and to enable output-to-file also for the 'freq' command. thanks, sven
