Hello,
It may be a very basic question, but I could not find the solution in archives or the documentation. I need to make a line plot (in square aspect ratio) and then save the figure which is also square in size, i.e. like 600x600 pixels and not 800x600. How can I acheive this?
to get the square axes, I used
ax.set_aspect(1./ax.get_data_ratio())
but I have no idea how to save the fig also in a square format.
thanks in advance,
stupid me…
I found the solution which is to use figure parametrs…
rcParams[‘figure.figsize’] = (6,6)
or something like that… well now I extend my question , i.e., how to make sure that my axis labels are not truncated due to this?

I think what you want here may be something like
fig = figure(figsize=(6, 6), dpi=100)
ax = fig.add_subplot(1,1,1)
[... plotting commands]
ax.set_aspect('equal', adjustable='box')
fig.savefig('mysquarefig.png', dpi=100)

thanks in advance,

Yes Eric this is what I wanted and Many thanks for your help.
My question now extends a little. Due to this … my yaxis label is truncated in the png. How can I make sure that my figure is square and also contains everything. Is it possilbe?
Thanks again,

There is no standard automatic method; you have to adjust the position of the axes within the figure. You can either specify the position explicitly by using
ax = fig.add_axes([l,b,w,h]
in place of add_subplot, and with l, b, w, h being left, bottom, width, and height in normalized coordinates (i.e., fractions of the figure window), or you can use fig.add_subplot together with fig.subplots_adjust(**kwargs).
Either way, to figure out how to set the l,b,w,h, you can first make the plot interactively and use the "Configure subplots" tool (next to last on the right) in the toolbar to interactively adjust the axes position and to show you what the values are that make it look right.
The default axes and subplot positioning parameters are also available via rcParams.
