Editing a Characteristic Map

Note
This instruction applies only to characteristic maps where each axis has maximal 63 elements. Larger characteristic maps can be edited in the same way as large arrays/matrices; see Editing Data of a Large Array or Matrix.

Open the data editor for the table.
Adjust the number of sample points in the "x-Size" and "y-Size" boxes.
This creates a table with m sample points on the x-axis and n sample points on the y-axis of the table. By default, they are assigned values from 0 to m-1 and 0 to n-1.
Adjust the sample points:
1. Double-click a cell in the "x" row.
  The "Edit x-axis point" dialog window opens.
2. Enter a value and click OK.
  Decreased values are marked by a downward arrow, increased values are marked by an upward arrow:
3. Double-click a cell in the "y" column and edit the y sample point in the "Edit y-axis point" dialog window.
Adjust the values:
1. Double-click a table cell that does not belong to an axis.
  The cell becomes an input field.
2. Type in a value and press <Enter>.
  Increased/decreased values are marked by the same arrows as the sample points.
3. Repeat for all the other values.
Click OK.

The interpolation mode is selected in the Properties editor of the characteristic map. It cannot be changed in the table editor.

The extrapolation mode is always set to Constant. For all x- or y-values greater than the highest x-/y-value defined in the table, the value returned is the value of the highest x-/y-value. For values that fall below the lowest x- or y-value, the value of the lowest x-/y-value is returned.
