You might be able to recover some by opening it as a script IF the information is there. For example I saved graph like this
with embedded data and the script looks like this
Local Here(
table1 = Open("$SAMPLE_DATA/Big Class.jmp");
table1 << Graph Builder(
Size(528, 454),
Show Control Panel(0),
Variables(X(:height), Y(:weight)),
Elements(Points(X, Y, Legend(6)), Smoother(X, Y, Legend(7))),
SendToReport(
Dispatch({}, "Graph Builder", FrameBox,
{Add Text Annotation(
Text("test"),
Fixed Size(0),
Text Box({91, 45, 130, 72}),
Filled(0)
), Add Polygon Annotation(
Points(
{161, 186},
{92, 141},
{23, 62},
{107, 4},
{183, 32},
{198, 71},
{62, 115}
),
Color("Blue"),
Closed(1)
)}
)
)
);
)
which is able to recreate the report.
You might also want to contact JMP Support about this.
