6. Variable Data (VARS) Menu

To recall variable data, press
{V-WIN}/{FACT}/{STAT}/{GRPH}/{DYNA}/{TABL}/{RECR}/{EQUA}/{TVM}/{Str}
• Note that the EQUA and TVM items appear for function keys (
access the variable data menu from the RUN • MAT (or RUN) or PRGM mode.
• The variable data menu does not appear if you press
hexadecimal is set as the default number system.
• Depending on the calculator model, some menu items may not be included.
• For details about the commands included on the variable data (VARS) menu, see the "
key" item in the "PRGM Mode Command List" (page 8-37).
• Item names below that are marked with an asterisk (*) are not included on the fx-7400G .

* The dot value indicates the display range (Xmax value – Xmin value) divided by the
screen dot pitch (126). The dot value is normally calculated automatically from the
minimum and maximum values. Changing the dot value causes the maximum to be
calculated automatically.
