python中griddata插值

  用 griddata插值时  'numpy.ndarray' 对象不可调用

 
zuobiao = np.concatenate((lon,lat),axis=1)
xnew = np.linspace(95,107,500)
ynew = np.linspace(20,29,500)

xnew,ynew = np.meshgrid(xnew,ynew)

grid = griddata(zuobiao, dis, (xnew, ynew), method="linear")

znew = grid(xnew,ynew)

znew 这里因该怎么写才对？

关于该问题，我找了一篇非常好的博客，你可以看看是否有帮助，链接：Python函数：生动解释二维插值函数：griddata()
