Matplotlib Example

Hello! ... I reported the following issue in the Matplotlib repo... and they said to bring it to your attention:

The Matplotlib Sample: "Plot Precip With Filled Contours"
https://matplotlib.org/basemap/users/examples.html

code source: https://matplotlib.org/basemap/users/figures/plotprecip.py

seems to be dated... I say "seems" because this is my first week of python! :)

Code for reproduction
The variables as specified in your code do not seem to exist:
latcorners = nc.variables['lat'][:]
loncorners = -nc.variables['lon'][:]
lon_0 = -nc.variables['true_lon'].getValue()
lat_0 = nc.variables['true_lat'].getValue()

I'm guessing because that data is from 2006 and something has changed since then :)

I have been failing with new data located here:
http://water.weather.gov/precip/downloads/2018/01/24/nws_precip_1day_20180124_conus.nc

surely there is a way for matplotlib to cull the information needed from the file? if not I figure I'll do the long math..

use your code located here
code source: https://matplotlib.org/basemap/users/figures/plotprecip.py

but also notice that not only are the lat lon variables present, your variable:
prcpvar = nc.variables['amountofprecip']

will need to be adjusted to prcpvar = nc.variables['observation']

and the units are now inches instead of mm.

Here is the issue I submitted to matplotlib:

Bắt đầu với basemap/users/figures/plotprecip.py và so sánh các biến của nó với tệp NetCDF mới hơn được liên kết trong issue. Kiểm tra issue Matplotlib được tham chiếu để biết ngữ cảnh, sau đó cập nhật ví dụ để các trường dữ liệu và đơn vị của nó khớp với nguồn được hỗ trợ, rồi xác minh rằng ví dụ chạy được.
