Re: [Gretl-users] IRFs and CI plots

All gretl's graphics are handled by creating a gnuplot script, executing it and then sending the result to the display. All this is done transparently. When you edit a graph, you modify the underlying gnuplot script via some GUI elements, so when you click "Apply" the graphic gets re-generated. This is where the problem is: gretl's GUI interface for modifying graphics can't handle arbitrary gnuplot scripts (nor we want it to: we're not interested in building a GUI interface to gnuplot, which is a vast and complex language), but only those generated internally. The figures generated by the SVAR package contain a few extra features that the GUI editor doesn't "understand", so if you invoke the GUI controls, it messes up the graph. However, you can customise the graph by editing the gnuplot script directly. Here's how: right-click on it and "Save [it] to session as icon". Then, in the icon view, right click on the graph icon and choose "Edit plot commands": you'll have the gnuplot source to the graph, that you can customise in any way you want. Of course, this entails some knowledge of gnuplot. However, if you click on the help icon while editing a gnuplot script the gnuplot manual in pdf will be downloaded and opened for you. PS: I hope you don't mind if I send this message to the user-list too, as others may want to ask the same question. ------------------------------------------------------- Riccardo (Jack) Lucchetti Dipartimento di Scienze Economiche e Sociali (DiSES) Università Politecnica delle Marche (formerly known as Università di Ancona) r.lucchetti(a)univpm.it http://www2.econ.univpm.it/servizi/hpp/lucchetti -------------------------------------------------------
