Python: subplot within a loop: first panel appears in wrong position

Question

I am fairly new to Python and come from a more Matlab point of view. I am trying to make a series of 2 x 5 panel contourf subplots. My approach so far has been to convert (to a certain degree) my Matlab code to Python and plot my subplots within a loop. The relavent part of the code looks like this:

fig=plt.figure(figsize=(15, 6),facecolor='w', edgecolor='k') for i in range(10):      #this part is just arranging the data for contourf      ind2 = py.find(zz==i+1)     sfr_mass_mat = np.reshape(sfr_mass[ind2],(pixmax_x,pixmax_y))     sfr_mass_sub = sfr_mass[ind2]     zi = griddata(massloclist, sfrloclist, sfr_mass_sub,xi,yi,interp='nn')       temp = 250+i  # this is to index the position of the subplot     ax=plt.subplot(temp)     ax.contourf(xi,yi,zi,5,cmap=plt.cm.Oranges)     plt.subplots_adjust(hspace = .5,wspace=.001)      #just annotating where each contour plot is being placed     ax.set_title(str(temp)) 

As a newbie to this forum, i dont seem to be allowed to attach the resulting image. However, going by my indexing in the code as 'temp' the resulting layout of the the 2 x 5 panels is:

251 - 252 - 253 - 254 - 255 256 - 257 - 258 - 259 - 250 

However, what i want is

250 - 251 - 252 - 253 - 254 255 - 256 - 257 - 258 - 259  

That is, the first panel (250) appears in the last position where i would think 259 should be. And 251 seems to be where i want 250 to be placed. They all seem to be in the correct sequence, just circularly shifted by one.

I know this will be something very silly, but appreciate any help you can give.

Thank you in advance.

Using your code with some random data, this would work:

fig, axs = plt.subplots(2,5, figsize=(15, 6), facecolor='w', edgecolor='k') fig.subplots_adjust(hspace = .5, wspace=.001)  axs = axs.ravel()  for i in range(10):      axs[i].contourf(np.random.rand(10,10),5,cmap=plt.cm.Oranges)     axs[i].set_title(str(250+i)) 

The layout is off course a bit messy, but that's because of your current settings (the figsize, wspace etc).
