For the Contour and Color-Filled Contour Plan View there is a Contour: Set button that brings up the Contour Properties Editor. The current contour interval is shown.
The control has a color bar showing the active color table and the associated high and low data values in the units the display is made in. As the mouse pointer is moved over the color bar, the value at a particular color is shown. Click on the color bar to start the Color Table Editor. Or click on the button that displays the name of the color table to show a popup menu that allows you to change the range, select other color tables, etc.
In the Color Shaded Plan View the Visible Range allows you to set the range
that determines what parts of the data is actually shown.
Click on the Levels box to see a pull down menu of the
native grid levels. Click on one level value to reset the
plan to that level. The plan level in use is shown
in the data's native altitude units.
The Levels box is editable. Click in the box, enter
a value and hit return to set your own value.
Click on the Cycle check box to animate
vertically through all available levels.
The color-shaded display has two modes. It comes up with interpolated colors: every pixel is colored to give a smooth gradation of color. The alternative is coloring an area of pixels corresponding to a single data grid cell with one color. Click off the Shade Colors box in the control window to see this display.
Another way to adjust the height of a Plan View through a 3D field is
to drag the selector point (a colored rectangle)
near the lower left corner of the plot to a
new height. The 3D display has to be rotated to see the display
somewhat from the side to do this. The color of this selector point
can be changed through the Edit->Selector Color menu.
