Auto Recalculation and Recalculate
"Auto Recalculation" is a setting item on the Settings menu. With the Spreadsheet app's initial default setting
(Auto Recalculation: On), all formulas in a spreadsheet are automatically re-calculated whenever you open
a file or perform an editing operation in the Spreadsheet app. Depending on the content of the spreadsheet,
auto re-calculation can take a long time to complete. When Auto Recalculation is disabled (Off), you need to
execute re-calculation manually as required.
To execute re-calculation manually
Select T > [Recalculate].
Note
• Even if the Auto Recalculation setting is On, you should execute T > [Recalculate] in the cases below.
- When the Settings menu is used to change the Angle setting
- When a cell contains a formula using an alpha variable or a function variable and the corresponding
variable is updated
Statistical Calculations and Graph Drawing
You can perform statistical calculations and draw statistical graphs using data input into a spreadsheet.
Inputting Data
Depending on the statistical data being processed, input the data using columns 1, 2, and 3 of the Spreadsheet
tab.
Input of 2-Variable data without frequencies
For this statistical data:
1-Variable (no frequencies)
1-Variable (with frequencies)
2-Variable (no frequencies)
2-Variable (with frequencies)
*1 In the Spreadsheet app Setup tab, specify the cell range for data being used for 1-Variable statistical
calculation to 1VarXCell (or XCellRange), the cell range for data being used for 2-Variable statistical
calculation to 2VarXCell, 2VarYCell (or XCellRange, YCellRange).
*2 In the Spreadsheet app Setup tab, the cell range of frequency data used for 1-Variable statistical calculation
is displayed as 1VarFreq (or Frequency), while the cell range of frequency data used for 2-Variable statistical
calculation is displayed as 2VarFreq (or Frequency).
Frequencies
There are two ways to input statistical data: with frequencies and without frequencies (1 is used for all data
frequencies). You can specify which method you want to use on the Setup tab that appears when you press
> on the Spreadsheet tab, as shown in the example below.
Input like this:
Input variable-X data (1VarXCell
Input variable-X data (1VarXCell
*2
data (1VarFreq ) into the second column.
Input variable-X data (2VarXCell
*1
data (2VarYCell ) into the second column.
Input variable-X data (2VarXCell
*1
(2VarYCell ) into the second column, and frequency data (2VarFreq
into the third column.
