[ncl-talk] Could I add some FillPatterns effect such as obliquelines to a raster fill plot ?

[xianglin72]

Hi, Adam


   Thank you the reply. I've tried what you have told before sending the first mail( see the attached script), however, I can not get what you and I expect ( see the attached plot).
   I've checked the explaination on the resource of "raster fill", and found the following :


 The following resources can be used to control fill features whencnFillModeis set toRasterFill:
cnFillColorscnGridBoundFillColorcnMissingValFillColorcnOutOfRangeFillColorcnRasterSmoothingOncnRasterMinCellSizeFcnRasterSampleFactorFcnRasterCellSizeF


  So you can find that the cnMonoFillColor and cnFillPattern can not work for this mode, which I've said in the first mail.


  Since the "AreaFill" mode can not get the same effect and the "cnFillPattern" resource can not be used for "CellFill" and
"rasterfill" mode, I still don't know how to add some shading effect for the chosen raster grids. 


Thanks


Lin

Hi Lin,

You can always do an overlay where you create two images:

1) Create a RasterFill plot with colors. (You already have this plot.)

2) Create a RasterFill plot with pattern fill (not color fill).


Then you would overlay 2) on 1) using the overlay procedure. 


See example #10 here:
http://www.ncl.ucar.edu/Applications/overlay.shtml#ex10


Note that for plot 2) (or plot_shade in example 10) you would want to set the following resources:

res at cnFillPattern = 3 

res at cnMonoFillColor = True

res at lbLabelBarOn = False ; no labelbar needed


Available fill patterns:

Hope that helps. If not, please respond to ncl-talk.

Hi, all


  I've made a raster fill plot ( see the attachment), and I want to add some FillPattern effect for some chosen cells in the plot.


However, I found that the resource of cnFillPattern can not work for the raster fill plot.  How could I do to add some effect,


for example, some oblique lines to the chosenrectanglar cells?  




Thanks




Lin
