From the Resources menu select the Surface Manager
command:
The Surface Manager shows a scrollable list of all the currently
defined interpolation surfaces. To create a new surface, click
the New... button. You will then be presented with the
Interpolation Surface Editor window:
Follow these steps to create a new colorbar:
1) Enter the 4 character parameter name for the interpolation
surface. If your parameter name is less than 4 characters, add
spaces at the end of the name until you have 4 characters. This
parameter name should match measured parameter names in the
data file or one that will be computed from measured values.
2) Enter a title for the interpolation surface. The title is
used creating a name for the interpolation surface when saved
to disk.
3) Enter an optional description for the interpolation surface.
4) Enter the number of values in this interpolation surface.
Maximum is 128.
5) Enter the range of values described by this interpolation
surface
6) Now click one of the shape buttons to create the initial
interpolation surface. The interpolation surface will be previewed
in the Level editor panel below.
If you are happy with your interpolation surface you can save
it to disk by clicking the Save... button. The following
steps are useful if you want to further refine your interpolation
surface --either it's shape or assigning specific values.
7) You can change the value of any level by first clicking
on it's symbol in the graph panel. You can then use the up/down
arrow keys to adjust the value of the point. You can also type
in a new value for the point in the text box and clicking the
Apply button. Tip: After you have selected one of the
symbols on the graph, you can use the left/right arrow keys
to move to the next point. Tip: Clicking and holding the mouse
down in the graph allows you to "paint" a interpolation surface
graph in any shape you wish.
