I have a figure with 2 subplots (2 rows, 1 column) created using the
OO interface like this:
ax1=fig.add_subplot(2,1,1)
ax2=fig.add_subplot(2,1,2)
After I have created these axes and plotted things on them, I want to
be able to set their x and y lims. The function that creates the plot
returns fig. I can then get to a list of the axes from fig.axes. My
question is this: can I know from the list of axes or their individual
properties which one is which - i.e. which one is the top one and
which one is the bottom one? It looks like ax1.rowNum and colNum
should refer to the parameters I want (rowNum in this case, since
there is only one column). But there isn't a docstring for them. Is
this there intended use (or at least a safe use of them)?
99% of the time, I will create the top one first so topfig=fig.axes[0]
and bottomfig=fig.axes[1]. But if I ever screw that up, it could be
bad.
Thanks,
Ryan
If you are creating subplots, you can do
rows, cols, num = ax.get_geometry()
You can also change the geometry with set_geometry.
There are a couple of Subplot helper functions you may find useful, eg
to selectively apply x and ylabeling:
def is_first_col(self):
return self.colNum==0
def is_first_row(self):
return self.rowNum==0
def is_last_row(self):
return self.rowNum==self.numRows-1
def is_last_col(self):
return self.colNum==self.numCols-1

Thanks John. That will work.
