You can look at matplotlib.image.NonUniformImage. But that only assists with having nonuniform axis - I don't think you're going to be able to plot adaptively like you want to (I think each point in the image is always going to have the same area - so you are going to have to have the wider rows multiple times). Is there any reason you need to plot the full array? Obviously the full detail isn't going to show up in any plot - so I would suggest heavily downsampling the original matrix so you can copy rows as required to get the image without running out of memory.
