import matplotlib.pyplot as plt

rainfall = np.load("/home/c052/work/opendata/21080606/rainfall.npy")

t2m = np.load("/home/c052/work/opendata/21080606/t2m.npy")

ygrids, xgrids = rainfall.shape

xx, yy = np.meshgrid(np.linspace(0, xgrids-1, xgrids),np.linspace(0,ygrids-1, ygrids))
raincb = cwbcolor.rain() #使用rain()方法，回傳雨量colorbar的物件
plt.contourf(xx, yy, rainfall, **raincb)

#設定「直」的colorbar跟tick label
cbstr = [ str(i) for i in raincb["levels"][1:-1]]
cbar = plt.colorbar(ticks=raincb["levels"][1:-1])
newticks = cbar.ax.set_yticklabels(cbstr)
