Stipple plots
*************


Example 17 - stipple plot
-------------------------

.. image::  images/fig17.png
   :scale: 44%

::

   import cf
   import cfplot as cfp
   f=cf.read('cfplot_data/tas_A1.nc')[0]
   g=f.subspace(time=15)
   cfp.gopen()
   cfp.cscale('magma')
   cfp.con(g)
   cfp.stipple(f=g, min=220, max=260, size=100, color='#00ff00')
   cfp.stipple(f=g, min=300, max=330, size=50, color='#0000ff', marker='s')
   cfp.gclose()

Stipple plots are usually used to display significance.  The above is a test plot
with a temperature field stippled between two different limits.  A contour field
is displayed underneath to show that the stippling is in the correct regions.



Example 18 - polar stipple plot
-------------------------------

.. image::  images/fig18.png
   :scale: 44%

::

   import cf
   import cfplot as cfp
   f=cf.read('cfplot_data/tas_A1.nc')[0]
   g=f.subspace(time=15)
   cfp.gopen()
   cfp.cscale('magma')
   cfp.mapset(proj='npstere')
   cfp.con(g)
   cfp.stipple(f=g, min=265, max=295, size=100, color='#00ff00')
   cfp.gclose()
