Thanks Allin. I´ll review all this possible kind of error in gl.po Best regards __________________________ En 12/05/2014 20:43, Allin Cottrell escribiu: No, it has nothing to do with those settings. It's a problem with the translation of the graph title. In English this reads: "Correlations of %s and lagged %s" where the "%s" slots are filled with the names of two variables. In the Galician translation, however, single-quotes are placed around the two names: "Correlacións entre '%s' e '%s' retardada" Since single-quotes are used by gretl to delimit the string passed to gnuplot, the extra quotes break the plot.
