iris中的控制Vmin和Vmax是动画;

发布于 2025-01-31 18:37:31 字数 536 浏览 3 评论 0 原文

有人知道如何（如果？）我可以使用 iris.experiment。？

wind = iris.load_cube('/my/pp/file')
cube_iter = wind.slices(('longitude', 'latitude'))
ani = animate(cube_iter, qplt.contourf,vmin=0,vmax=20)
plt.show()

我正在使用IRIS 2.4.0版。

在此代码中，动画有效，但VMAX被忽略（请参阅附件屏幕截图）。

有人知道如何解决这个问题吗？

谢谢！

Does anyone know how (if?) I can control the vmin and vmax of an Iris quickplot pcolormesh animation using iris.experimental.animate.animate?

wind = iris.load_cube('/my/pp/file')
cube_iter = wind.slices(('longitude', 'latitude'))
ani = animate(cube_iter, qplt.contourf,vmin=0,vmax=20)
plt.show()

I'm using Iris version 2.4.0.

In this code, the animation works, but vmax is ignored (see attached screenshot).

Does anyone know how to fix this?

Thanks!

这有点像软糖，但是我们可以使用 functools.spartial 函数要修复 calle 和 Extend 关键字。

import functools

import iris
from iris.experimental.animate import animate
import iris.quickplot as qplt
import matplotlib.pyplot as plt

my_contourf = functools.partial(qplt.contourf, levels=range(260, 291, 5),
                                extend="both")
# Function defined by partial has no __module__ or __name__ attribute, so add
# them to get past iris animate's checks.
my_contourf.__module__ = "iris.quickplot"
my_contourf.__name__ = "contourf"

fname = iris.sample_data_path("E1_north_america.nc")
cube = iris.load_cube(fname)[:20]

cube_iter = cube.slices(('longitude', 'latitude'))
ani = animate(cube_iter, my_contourf, vmin=260, vmax=290)
ani.save("abc.gif")

This is a bit of a fudge, but we can produce a more sensible animation by using the functools.partial function to fix the levels and extend keyword.

import functools

import iris
from iris.experimental.animate import animate
import iris.quickplot as qplt
import matplotlib.pyplot as plt

my_contourf = functools.partial(qplt.contourf, levels=range(260, 291, 5),
                                extend="both")
# Function defined by partial has no __module__ or __name__ attribute, so add
# them to get past iris animate's checks.
my_contourf.__module__ = "iris.quickplot"
my_contourf.__name__ = "contourf"

fname = iris.sample_data_path("E1_north_america.nc")
cube = iris.load_cube(fname)[:20]

cube_iter = cube.slices(('longitude', 'latitude'))
ani = animate(cube_iter, my_contourf, vmin=260, vmax=290)
ani.save("abc.gif")
