如何创建可重复使用的底图 [英] How to create a reusable basemap

问题描述

在继续我的上一个问题:如何在matplotlib中叠加数字我想知道如何创建一个可重用的basemap对象. 我的问题是basemap不是pyplot对象，因此我收到的解决方案在figures / axes上效果很好，但在basemap对象上效果不好.

In continuation to my previous question: How to superimpose figures in matplotlib i would like to know how can one create a reusable basemap object. My problem is that a basemap is not a pyplot object, so the solution i received works well on figures / axes but not on basemap objects.

我试图四处寻找解决方案，但找不到任何东西，只是讨论而已.

I tried to look around and find a solution, but couldn't find any, just discussions.

推荐答案

在此感谢@JoeKington和位于

Thanks to @JoeKington here and @EdSmith at How to superimpose figures in matplotlib, i was able to understand how to achieve what i wanted: reuse basemap objects and pass them around.

我是这样做的:

1. 创建了一个具有两个功能的base_map.py:plot()创建一个地图对象并绘制一些属性，另一个set_a_map()创建一个空地图对象.

2. 在我添加到绘图功能的其他模块中，添加了map=None属性，在每个功能中，我添加了:

1. Created a base_map.py that has two functions: plot() that create a map object and draw some properties and another one, set_a_map() that create an empty map object.

2. In the other modules i added to the plot functions a map=None property, and in each function i added a:

if not map:  
    map = base_map.set_a_map()

因此，如果没有将地图对象传递给另一个函数，则该函数将创建一个新的地图对象.

So that in case that no map object being passed to the other function, the function will create a new map object.

在我的绘图功能中，例如，我使用的是map.imshow(...)，而不是使用plt.imshow(...).这样，我的数据将被绘制在地图上.

In my plot functions, instead of using plt.imshow(...) for example, i'm using map.imshow(...). This way my data will be plot over a map.
