I have created a matrix plot and a line and combined them as follows:

m = matrix_plot([[1,0,1,0,1,0,1,0],
                 [0,1,0,1,0,1,0,1],
                 [1,0,1,0,1,0,1,0],
                 [0,1,0,1,0,1,0,1],
                 [1,0,1,0,1,0,1,0],
                 [0,1,0,1,0,1,0,1],
                 [1,0,1,0,1,0,1,0],
                 [0,1,0,1,0,1,0,1],
                 [1,0,1,0,1,0,1,0]],
                aspect_ratio=1,
                frame=False)
Q = line([(-0.5, 0), (1, 1)], thickness=3)

Combined graphics is (m+Q).

I would like to change the size of (m+Q), but (m+Q).set_axes_range() does not affect the values.

Here is an example showing no change when using set_axes_range():

What method should I use?

You need to give m + Q a new name.

Otherwise when you do (m + Q).set_axes_range(...) that gets applied to an object which you can no longer recover.

And when you later do (m + Q).get_axes_range(...) you are computing m + Q again and that cannot know about the operation you did on the lost object.

Try this:

sage: mQ = m + Q
sage: mQ.set_axes_range(xmin=-0.2, xmax=5.5, ymin=-0.5, ymax=1)
sage: print(mQ.get_axes_range())
sage: mQ.show()

Yes, that makes perfect sense!

I need to create a reference to this combined object - as you suggested mQ = m+Q allows me to do mQ.set_axes_range(...)

Merci Beaucoup! Une réponse le jour même de Noël!
