Detailed Description

Plot used to show raster (image-like) data.

Expected to use PlotRasterData. The line methods in Plot are used for contour lines (if any). A RasterPlot can either use the data values directly as colors, or automatically pick colors based on a range of values and a colorbar. (See PlotRasterData.)
