[ncl-talk] How to define the size of color box when drawing a contour map using res at cnFillMode= "RasterFill" ?

[Karin Meier-Fleischer]

Hi Xiaofeng,

the size of the color boxes refers to the data values of the grid cells 
- they have the same size.

See:
http://ncl.ucar.edu/Document/Graphics/Resources/cn.shtml

/|RasterFill|/
    /*ContourPlot*
    <http://ncl.ucar.edu/Document/HLUs/Classes/ContourPlot.shtml>//generates
    a representation of the data by individually assigning colors to the
    elements of a two-dimensional array of rectangular cells (a raster
    array) superimposed on an area bounding the data grid. With raster
    mode, only solid fill is possible, and therefore resources related
    to fill pattern specification have no effect. //*The color of each
    cell is determined based on the fill color assigned to the data
    value at the cell's location.*//../

If you have the impression that the color boxes are bigger than the grid 
cells, maybe there are more than one grid cell filled with the same 
color because they have the same data value.

Bye,
Karin
