Wolfram Research says it no longer supports JavaGraphics in Mathmatica 10. This is very bad for people who prefer the Kernel to the FrontEnd.
However, I am still able to get it to work.
Show failed. However, this works:
show[x__] := Show[x, DisplayFunction->$DisplayFunction ]
Also, ErrorListPlot fails, but this works:
Needs["ErrorBarPlots`"] errorListPlot[x__] := show [ ErrorListPlot[x] ]
I put these definitions in my init.m file.
Sorry this isn't a question ... more of a tip.
