Graph Database

There are several differences between TI-92 graph databases and
TI-89 / TI-92 Plus graph databases which are noted below. TI-92 graph
databases can be sent to the TI-89 / TI-92 Plus but TI-89 / TI-92 Plus graph
databases cannot be sent to a TI-92. Once it is received by the
TI-89 / TI-92 Plus, a TI-92 graph database still has the TI-92 version number
(version=TV_TI_92 in the SYM_ENTRY structure for that variable in the symbol
table, see section 13.3 Managing Variables), which allows it to be sent to
another TI-92 from the TI-89 / TI-92 Plus.
Description
Data length of Graph Database
Number of Graphs (1 = one graph mode, 2 = two graph mode)
Angle Mode (Radian = 1, Degree = 2)
Real/Complex Mode
Graph Mode — Graph 1 (if in two graph mode this is the graph on
AP_SIDE_A)
Active Side — two graph mode only (0 = gr_active pointing to graph 1,
1 = gr_active pointing to graph 2)
Graph Mode of Graph 2 — two graph mode only (see above graph modes
for values)
