You can manually turn off autoscaling on the axes instance with the
following, and both scatter and plot should then work as you want.

ax1 = subplot(121)
axis('off')
ax1.imshow(rand(20,20))
ax2 = subplot(122)
axis('off')
ax2.imshow(rand(20,20))

ax1.set_autoscale_on(False)
#ax1.scatter([5,10],[5,10])# note 2
ax1.plot([5,10],[5,10], 'o') # note 3
show()

Hey Gary, thanks for the resend.

On your first question vis-a-vis subplots_adjust, it looks like the
validate limits are wrong for these params.  I'm CC-ing Darren because
he has done the most work recently for rc param validation.

They currently read:

'figure.subplot.left'   : [0.125, ValidateInterval(0, 1,
closedmin=False, closedmax=False)],
'figure.subplot.right'  : [0.9, ValidateInterval(0, 1,
closedmin=False, closedmax=False)],
'figure.subplot.bottom' : [0.1, ValidateInterval(0, 1,
closedmin=False, closedmax=False)],
'figure.subplot.top': [0.9, ValidateInterval(0, 1,
closedmin=False, closedmax=False)],
'figure.subplot.wspace' : [0.2, ValidateInterval(0, 1,
closedmin=False, closedmax=True)],
'figure.subplot.hspace' : [0.2, ValidateInterval(0, 1,
closedmin=False, closedmax=True)],

and I think they should read:


'figure.subplot.left'   : [0.125, ValidateInterval(0, 1,
closedmin=True, closedmax=True)],
'figure.subplot.right'  : [0.9, ValidateInterval(0, 1,
closedmin=True, closedmax=True)],
'figure.subplot.bottom' : [0.1, ValidateInterval(0, 1,
closedmin=True, closedmax=True)],
'figure.subplot.top': [0.9, ValidateInterval(0, 1,
closedmin=True, closedmax=True)],
'figure.subplot.wspace' : [0.2, ValidateInterval(0, 1,
closedmin=True, closedmax=False)],
'figure.subplot.hspace' : [0.2, ValidateInterval(0, 1,
closedmin=True, closedmax=False)],

That is, 0 and 1 should be legal for all values except the max of the
wspace and hspace.  Darren, unless I am missing something, I'll commit
these changes.

I'll look at your second question in a followup
