A corn plant knows how to find water in soil with the very tips of its roots, but some varieties, including many used for breeding high-yielding corn in the U.S., appear to have lost a portion of that...

I have the following code that when run separately, displays two maps: Map1: f = h5py.File(filename[0], 'r') group_id='Soil_Moisture_Retrieval_Data_AM' var_id = 'soil_moisture' a = f[group_id][var_id][:,:] plt.figure(figsize=(10, 10)) a[a==f[group_id][var_id].attrs['_FillValue'].astype(int)]==np.nan; plt.imshow(a,vmin=0.,vmax=0.55, cmap = 'terrain_r'); cbar = plt.colorbar(orientation='horizontal') cbar.set_label('$cm^3 cm^{-3}$') Map2: f1 = h5py.File(filename[1], 'r') b = f1[group_id][var_id][:,:] b[b==f1[group_id][var_id].attrs['_FillValue'].astype(int)]==np.nan; plt.figure(figsize=(10, 10)) plt.imshow(b,vmin=0.,vmax=0.55, cmap = 'terrain_r'); cbar = plt.colorbar(orientation='horizontal') cbar.set_label('$cm^3 cm^{-3}$') Trying to overlay the two maps will only display the last line (in this case, b): plt.figure(figsize=(10, 10)) plt.imshow(a,vmin=0.,vmax=0.55, cmap = 'terrain_r') plt.imshow(b,vmin=0.,vmax=0.55, cmap = 'terrain_r') What am I possibly missing? Happy to provide more info if needed...

Vernier's Go Direct® Soil Moisture Sensor is revolutionizing STEM education by allowing high school and college students to accurately measure soil moisture for various sciences.
