I am trying to reposition and stretch a curvilinear coordinate axis created with floating_axes.FloatingSubplot after the axis has been created. In an older version of matplotlib, I was able to do this successfully with code the following code:
horiz = [Size.Scaled(1.0)] vert = [Size.Scaled(1.0)] ax1_div = Divider(fig,[0.0, 0.0, 1.0, 0.45],horiz,vert,aspect=False) # Curvilinear Coordinates ax1_loc = ax1_div.new_locator(nx=0,ny=0) # Curvilinear Coordinates ax1.set_axes_locator(ax1_loc) # Curvilinear Coordinates In the image below, I want to be able to stretch the curvilinear coordinate system so that its x-axis is aligned with the rectangular coordinate system. Older versions of matplotlib did this, but in matplotlib version 3.3.4 I can only get the axis to translate, but not stretch.
Does anyone know how to do this? ax.set_position() does not work here. My problem is similar to this question which received no answers.
Here is my code that generated the figure:
