Displays a series of user defined contours along a two dimensional plane within the user’s domain.
The Contour Renderer has specialized controls in its Appearance tab, under the heading “Contour Properties”.
Spacing controls the incremental increase in data value between contours
Count controls how many contours are currently being drawn
Contour Minimum sets the value of the lowest valued contour in the series
Renderers that work with 2D data can make use of a height variable. When a height variable is specified in the Variables tab, the rendering in the two-dimensional plane willbe offset by the values of that height variable.
