Explorer Sample Map 4
Sample Map - Slicer & Annotation
Description
Similar to "simple_slicer_sample_1.map", this map reads in NMC global data using ReadNC, extracts a slice orthogonal to any axis, and renders it as a color-shaded plane positioned within a bounding box representing the 3-dimensional extent of the data. In this case, one of two colormaps can be chosen (via the "Multiplexor" module), the first stretching over the entire volume of data values, the second over the data values in the slice only. The filename and variable name are placed at the top of the rendered image. A histogram of the entire data variable is given.
A "GenerateColormap" module is placed in-line along on of the paths to show how the colormap might be manipulated. (However, it is reset every time a new slice or new variable is chosen.)
Remember that some caution is needed when switching from displaying a 2-D variable to a 3-D variable. In ReadNC, Kstart and Kend will both be set to 1, which was appropriate for the 2-D variable where the third dimesnion (K) was time and there was only 1 time in the file. You'll have to reset Kend to get the entire span of vertical coordinates for a 3-D variable when it is selected.
