A Raster-filled plot can work 2 different ways depending on the setting of the resource "cnRasterSmoothingOn". If cnRasterSmoothing is set False (the default), then the color assigned will depend on the value associated with the grid box or boxes that occupy the most area around the data value. Note that depending on the raster resolution there can be less than one or more than one data value contained in a single raster cell. <div>If cnRasterSmoothing on is set True then the value associated with a raster cell is calculated as a area-weighted average of all the data values within the cell.
