Thread: [Matplotlib-users] Subplot of subplots.

Hi, I am using add_subplot(...) to create a row of 4 plots, and have a tricky
question.
I have an image (a figure instance) composed of 4 subplots in a single row.
I'd like to know how to arrange a number of these rows in a bigger grid,
namely a grid of 10x3 plots, each plot made up of 1x4 subplots. The ideal
solution would be:
* function that returns 1x4 plots
* call that function repeatedly
I tried to do this with
def function(figure, which_one, index):
  grid = ImageGrid(figure, 10,3,index, nrows_ncols = (1, 4))
  grid[0].imshow(something(which_one))
  grid[1].imshow(.....)
  ...

however the plots apparently share the y axis, which for me is unfeasable
as:
1) the first of 4 images has about 10000 pixels, while the others have 24
(6x4 pixels): no chance they can be on the same scale!
2) I want to plot a colorbar on top of the 6x4 subplots.
3) I want to write labels on top of the 6x4 subplots.

This is what grid produces: an ugly white space if y axes don't have the
same length.

This is my best attempt, still a lot of work to do, but don't know how to
tile several of these in a 10x3 array.

Thank you very much.

Desperately,

There are a few options you can try. And I recommend you to use gridspec module.

It can also be used with ImageGrid (at least in the master branch, but
not sure for 1.0.1 release).

I'm attaching a sample script.
