The x and y scales (as set by aspect) will be free to change independently, distorting the circle: In the basic case (no fixed aspect ratio set for the axes), the axes will fill up the entire space allocated to it in figure coordinates (shown by the green box). To understand how everything interacts, let's plot a circle in lots of different cases. Depending on the aspect and adjustable parameters, the Axes will shrink inside of its given extent. However, the extent the axes is given (either from its subplot location or explicitly set extent) isn't necessarily the size it will take up. (Note: Some things such as axes_grid will change this at draw time to get around this limitation.)
The mechanism that the Axes uses to accommodate a fixed aspect ratio (the adjustable parameter).Īxes are always placed in figure coordinates in other words, their shape/size is always a ratio of the figure's shape/size.the subplot location, shown in green in figures below) The specified extent of the Axes in figure coordinates (e.g.The size/shape of the Figure ( shown in red in figures below).There are three things that control the size and shape of the "outside box" of a matplotlib axes: It doesn't directly control the ratio of the width and height of the axes. Let me back up and explain what's going on in detail.Īspect in matplotlib refers to the ratio of the xscale and yscale in data coordinates. However, this is a common source of confusion in matplotlib. This will override any aspect you specify when you create the axes. Imshow will set the aspect ratio of the axes to 1 when it is called, by default. You're probably wanting to call: ax.imshow(., aspect='auto') All I need to do now is adjust the subplot size so that sub-plots are plotted in a portrait aspect ratio of eg 2:1, but with the plot filling the entire sub-plot. When I set' aspect='auto'' the plot looks like this: Thanks also to the other posters for their suggestions. Thanks in - thank you! That was a great reply!! Still trying to get my head around it all. I also switched 'autoscale' off but I can then only see a handful of pixels. I have tried using ax.set_aspect and passing 'aspect' as a subplot_kw argument but to no avail.
I want to change the aspect ratio so that the plots are squashed vertically and stretched horizontally. Img = ax.imshow(plot_data, interpolation='none')

I have created a series of simple greyscale images which I have plotted in a grid (unfortunately, can't upload an image because I don't have a high enough reputation :( ).
