How can I set the contour interval in Voxler?

 

The Level method in the Property Manager is the parameter that controls the interval for the Contours module. There are 4 modes for the levels for a contour map in Voxler: Automatic; Min, max, count; Min, max, interval; and Explicit. To change the method, you will need to have the Contour module selected in the Network Manager, and on the General tab of the Property Manager click next to Level method. The various methods are detailed below:

  • Automatic uses the data limits to display the specified number of contour levels. The minimum and maximum levels are offset from the data minimum and maximum by an amount equal to the data range divided by twice the number of levels. When attaching a new Contours module to a lattice, the default number of levels is 5, so the offset is 10% of the data range. 
  • Min, max, count displays the specified number of contour levels with equal spacing from the specified minimum to the specified maximum values. Use the calculations in the example for the Automatic method to calculate the contour interval and values of the contour levels. If the Minimum level or Maximum level values are not present in the specified cutting plane, not all of the specified number of levels are displayed.
  • Min, max, interval displays contour levels with the specified interval ranging from specified minimum and maximum. If the Minimum level or Maximum level values are not present in the specified cutting plane, not all of the specified number of levels are displayed.
  • Explicit allows you to enter a space-separated list of contour levels to be displayed. If a level is outside the data range, it is not displayed.
