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.
The Texture Quality allows you to set the quality of
the displayed texture of Color Shaded Plan View. A higher
quality will take longer to render and use more memory. Move
the slider to select the quality you want.
This control has an option to smooth the grid that can be used to smooth contour lines or flow fields for display. There are 6 types of smoothing: 5-point, 9-point and gaussian weighted, Cressman, circular and rectangular aperture smoothers. The amount of smoothness can be set for the gaussian smoother. The higher the amount, the smoother the grid. For the Cressman, circular and rectangular aperture, the factor is the radius in grid spacing units.
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.
The Mode selector allows you to set the way
the texture is displayed. You can select Solid, Mesh,
or points. This is useful for looking at the structure
of the underlying data used to create the Color Shaded Plan View.
