Jan 16, 2018 · So how can I make the x and y values for the contourf() something that cartopy can handle in 3D? Neither cartopy nor Basemap are able to manage 3D figures. The only solution is to calculate the coordinates prior to plotting them on a cartesian matplotlib 3D plot.

import matplotlib.pyplot as plt import cartopy.crs as ccrs from cartopy.examples.waves import sample_data ax = plt. axes (projection = ccrs. Robinson ()) ax . set_global () lons , lats , data = sample_data ( shape = ( 20 , 40 )) plt . contourf ( lons , lats , data , transform = ccrs .

Jul 12, 2017 · The essence is the use of zorder and alpha in plt.contourf() that can be set to show or hide some features on the map.

Sep 8, 2018 · Using cartopy, I'm trying to plot filled contours in a projection centered on a non-zero longitude: from pylab import * from cartopy import crs xi = linspace(-180, 180, 37) yi = linspace(-90, 90,...

contourf fills intervals that are closed at the top; that is, for boundaries z1 and z2, the filled region is: z1 < Z <= z2 except for the lowest interval, which is closed on both sides (i.e. it includes the lowest value).

It uses the transform_first keyword argument to indicate that Cartopy should transform the points before calling the contouring algorithm, which can have a significant impact on speed (it is much faster to transform points than it is to transform patches).

Feb 24, 2021 · matplotlib.pyplot contourf coutour([X, Y,] Z,[levels], **kwargs) 是来绘制等高线的，contour和contourf都是画三维等高线图的，不同点在于contour() 是绘制轮廓线，contourf()会填充轮廓。除非另有说明，否则两个版本的函数是相同的。

Apr 16, 2020 · This notebook will demonstrate how to make multi-panel contour plots with Cartopy, including adding a single colorbar and title for all panels. Data ¶ The Subseasonal Experiment (SubX) ¶

Cartopy comes with powerful vector field plotting functionality. There are 3 distinct options for visualising vector fields: quivers (example), barbs (example) and streamplots (example) each with their own benefits for displaying certain vector field forms.

Dec 2, 2021 · I try to create a geographical map using contourf including shaded areas (indicating significance). Here is a MWE: import numpy as np import matplotlib.pyplot as plt import cartopy.crs as ccrs lat...
