MeteoInfoLab脚本示例：fill_between

MeteoInfo

fill_between()函数用来填充两条曲线之间的区域，前三个参数分别是x, y1, y2，填充的是y1和y2之间的区域。where参数可以控制填充某些符合条件的部分区域。该函数的帮助文档：http://www.meteothinker.com/docs ... t/fill_between.html

示例脚本：

1. n = 256
   
2. X = linspace(-pi,pi,n,endpoint=True)
   
3. Y = sin(2*X)
   
4. 
   
5. fill_between(X, 1, Y+1, color='blue', alpha=.25)
   
6. plot(X, Y+1, color='blue')
   
7. 
   
8. fill_between(X, -1, Y-1, (Y-1) > -1, color='blue', alpha=.25)
   
9. fill_between(X, -1, Y-1, (Y-1) < -1, color='red',  alpha=.25)
   
10. plot(X, Y-1, color='blue')
    
11. xlim(-pi, pi)
    
12. ylim(-2.5, 2.5)
    
13. title('fill_between example')

n = 256<br /> X = linspace(-pi,pi,n,endpoint=True)<br /> Y = sin(2*X)<br /> <br /> fill_between(X, 1, Y+1, color='blue', alpha=.25)<br /> plot(X, Y+1, color='blue')<br /> <br /> fill_between(X, -1, Y-1, (Y-1) > -1, color='blue', alpha=.25)<br /> fill_between(X, -1, Y-1, (Y-1) < -1, color='red',  alpha=.25)<br /> plot(X, Y-1, color='blue')<br /> xlim(-pi, pi)<br /> ylim(-2.5, 2.5)<br /> title('fill_between example')
