Hi everyone
I have install ferret v7.1(optimized) for 64 bit in ubuntu 16.04 lts. During installation no error come. But when run go tutorial in ferret, for all line plot the figures are showing ok, but as SHADE/i=1:40/j=1:40 cos(i/5)*sin(j/10) command run, the window showing blank, with level blank, same for fill commands also, I run shade and fill command using other data files also, no error is coming, but the figure window is only blank along with blank levels(i.e no colors)
please help me anyone. I have tried several times to resolve the issue...
