1.8.5 is the most recent release, and it incorporates an update to the included version of CVS gnuplot (several months' worth of fixes, as I recall), so it might be worth re-trying using that. > When I create a gretl graph object and "show" it, > I see the missing pixels problem. "show" -> gretl-controlled GTK window holding a PNG graphic created by gnuplot's PNG driver. There's more than one gnuplot driver that can do PNG, in general, but the wgnuplot.exe supplied with gretl for Windows always uses the newer cairo-based PNG driver. > However if I open the graph object code (menu: Edit Plot > Commands) and click the "run" icon... "run" -> the display of the graph is handed off to gnuplot itself, and on MS Windows this means that the Windows GDI driver gets used. Such a graph window is not controlled by gretl and doesn't offer the gretl graph-editing "extras". Allin
