Revision as of 18:39, 31 October 2023
New features, fixed bugs, and software news are shown here
A good concise list is provided in the official changelog, here the aim is to be more explicit and sometimes give some examples. Before the respective new gretl version is released, the examples will only work in snapshots that are recent enough, or with self-compiled bleeding-edge versions.
New in what will be gretl 2023c
(this is just a selection, not exhaustive)
gridplot command
This new native command makes it possible to arrange several subplots in a grid (rectangular) layout. As such it will pretty much replace the contributed function package multiplot. There are basically two ways of using it:
First, using some other plotting commands, redirect the output to a string buffer inside a strings array. Then execute the gridplot command on that array. Example:
open australia strings temparr = array(2) qqplot IAU --outbuf=temparr[1] kdplot E --outbuf=temparr[2] gridplot temparr --output=display
Secondly, use the companion command gpbuild in a block format, and then define the individual parts:
open data4-10
gpbuild MyPlots
gnuplot ENROLL CATHOL
gnuplot ENROLL INCOME
gnuplot ENROLL COLLEGE
end gpbuild
gridplot MyPlots --output=display
tsplots (virtual) command
You can now use the new tsplots command to create several joint time-series plots easily. Example:
open denmark tsplots LRM LRY --output=display
This has actually "always" been possible with the scatters command --and was duly documented-- but it was somewhat counterintuitive to use a command for scatter plots to draw time-series lines.
