152 Chapter 14: Data Types 14.7. 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 Mode Value Real 1 Rectangular 2 Polar 3 Graph Mode - Graph 1 (if in two graph mode this is the graph on AP_SIDE_A) Mode Value Function 1 Parametric 2 Polar 3 Sequence 4 3D 5 Differential Equations 6 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) Bytes 2 1 1 1 1 1 1 Table 14.11: Data Object for a Graph Database TI-89 / TI-92 Plus Developer Guide Not for Distribution Beta Version January 26, 2001
