I just installed the 1.02beta version of grtool on my sparcbox. It has lots of nice features, but I discovered an error in it unless I am misunderstanding something. I set up log-log axes and then transformed my data using the built in transformation window so that x=log(x) and y=log(y). However, when I plot the points they do not show up in the proper place on the graph. Simple example, I created test.dat with pairs 1,1; 10,10. World coordinates are set to -1,-1 and +2,+2. My pairs of points do not plot at 0,0 and 1,1 By trial and error I discover that points plot (at least approximately) correct if I transform x=log(x) + .2 and y=log(y) + .2 I am just a user, not a programmer. Can somebody give me a correction to the source code to fix this, or explain what I am doing wrong if it is a misunderstanding of the documentation on my part. Thanks,
