Visualisation¶

cf-plot¶

The cf-plot package provides metadata-aware visualisation for cf fields. This is a seperate library and cf does not depend on it.

The functionality of cfplot includes

Cylindrical projection plots
Polar stereographic plots
Latitude/longitude - height plots
Hovmuller plots
Vector plots
Stipple (significance) plots
Multiple plots on a page
Different colour scales
User defined axes
Rotated pole plots
Irregular grid plots
Graph plots

Examples¶

There are many and varied examples of using cf-plot with cf on the cf-plot homepage (http://ajheaps.github.io/cf-plot/). Two simple examples are shown here.

A simple 2-d contour plot could be produced as follows:

>>> import cf
>>> import cfplot
>>> f = cf.read_field('data1.nc')
>>> cfplot.con(f)

A simple 1-d line plot could be produced as follows:

>>> f = cf.read_field('data2.nc')
>>> cfplot.lineplot(f, marker='o', color='blue', title='Zonal mean zonal wind at 100mb')
