Sorry i’m a newbie for python and pygmt.
Now I am drawing a map showing precipitation in Hong Kong area. I only have data from some weather stations in Hong Kong including longitude 、 latitude and precipitation. By studying the manual, I’ll just color-code the precipitation for that stations,like this:
But I have two problems：①How to display only the range of Hong Kong, excluding other regions except Hong Kong？
②How to plot the precipitation within Hong Kong using only the precipitation from those stations？like this：
What should I do？Thank you all！！
