I have a tzt3 16 that has my main transducer and a dff3d. Both have temp. On the 16 I can set a graph with temp data over a certain time frame which I use alot. On my 2nd unit a tzt12f connected via network I can see SST on the initial setup sources and select either tzt16 or dff3d. But when I go to add the graph on the chart data section its greyed out?? Any suggestions? Could this be a bug?
