Editing a Characteristic Line
Note |
|---|
This instruction applies only to characteristic lines with maximal 2048 elements. Larger characteristic lines 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" box.
This creates a table with n sample points on the x-axis of the table. By default, they are assigned values from 0 to n-1.
Adjust the sample points.
Double-click a cell in the "x" row.
The "Edit x-axis point" dialog window opens.
Enter a value and click OK.
Decreased values are marked by a downward arrow, increased values are marked by an upward arrow:
- Modify the z-axis values as described in Editing an Array or Matrix.
- Click OK.
The interpolation mode is selected in the Properties editor of the characteristic line. It cannot be changed in the table editor.
The extrapolation mode is always set to Constant. For all x-values greater than the highest x-value defined in the table, the value returned is the z-value of the highest x-value. For values that fall below the lowest x-value, the z-value of the lowest x-value is returned.
The sample points are shown on the x-axis of the data area, the values are on the z-axis. By default the number of sample points that you entered in the Properties editor is created. The default sample points form a range between 0 and the number of sample points minus 1.
