| cntr | Set a contour |
| <graphic> | name of the graphic structure |
| -n <name> | name of the contour |
| -f <field> | field to be used for neurons |
| -v <value> | value for the contour (elevation) |
| [-co <color>] | color for the contour |
| [-t <type>] | how the contour is drawn |
| cntr <graphic> -n <name> -rm | Remove contour <name> |
The operation creates contour lines onto a TS-SOM layer. The contour line is placed based on the values of <field> in neurons and the specified value <value>. The field values in neurons are compared to the specified value, and the line goes through points, in which the interpolated field value between neighboring neurons equals to <value>.
Example (ex7.9): This example shows, how contours can be created. In this case a TS-SOM has been trained with Boston data. Three contours are created to describe the changes of weight rm_w with values 0.2, 0.3 and 0.4 on layer 3.
