Dear all, I'm trying to plot the projection of a variable defined in a rather involved way, namely through an IF statement. I can use this variable for many computations and I can plot slices of it, but somehow it does not work with projections. I attach an example script which isolates the problem. I guess it can run on any standard cosmological output of Enzo (v. 1.0; I haven't worked with Enzo 1.5 yet). As I told you, if I change the pc.add_projection(... at line 65 with pc.add_slice(... everything works well. I'm using YT 1.6, and because of problems in my machine I cannot upgrade to 1.6.1 until next week, so I don't know if this issue has been already fixed by chance. Looking forward to your suggestions, Cheers, Luigi -- --------------------------------------------------------------- Luigi Iapichino Zentrum fuer Astronomie der Universitaet Heidelberg Institut fuer Theoretische Astrophysik Albert-Ueberle-Str. 2, D-69120 Heidelberg, Germany Tel: +49 6221 548983, Fax: +49 6221 544221 e-mail: luigi@ita.uni-heidelberg.de URL: http://www.ita.uni-heidelberg.de/~luigi/
