Now in matplotlib version 3.3.4 I can only get the axis to translate, but not stretch.\r\n\r\n**Code for reproduction**\r\n\r\n```python\r\n#!/usr/bin/env python3\r\nfrom matplotlib import pyplot as plt\r\nfrom matplotlib.transforms import Affine2D, Transform\r\nimport mpl_toolkits.axisartist.floating_axes as floating_axes\r\nfrom matplotlib.projections import polar\r\nfrom mpl_toolkits.axisartist.grid_finder import FixedLocator, DictFormatter\r\nimport mpl_toolkits.axes_grid1.axes_size as Size\r\nfrom mpl_toolkits.axes_grid1 import Divider\r\n\r\nfig = plt.figure()\r\n\r\n# Generate first axis using normal methods.\r\nax0 = fig.add_subplot(111)\r\nax0.set_xticks([0,500,1000,1500,2000])\r\n\r\n# Generate a curvilear axis for the second axis.\r\nangle_ticks     = [(0, '0'), (0.079, '500'), (0.157, '1000'), (0.235, '1500'), (0.314, '2000')]\r\ngrid_locator1   = FixedLocator([v for v, s in angle_ticks])\r\ntick_formatter1 = DictFormatter(dict(angle_ticks))\r\n\r\nalt_ticks       = [(6371.0, '0'), (6671.0, '300'), (6971.0, '600'), (7271.0, '900'), (7571.0, '1200')]\r\ngrid_locator2   = FixedLocator([v for v, s in alt_ticks])\r\ntick_formatter2 = DictFormatter(dict(alt_ticks))\r\n\r\ntr_rotate       = Affine2D().rotate(1.414)\r\ntr_shift        = Affine2D().translate(0, 6371)\r\ntr              = polar.PolarTransform() + tr_rotate\r\n\r\ngrid_helper = \\\r\n    floating_axes.GridHelperCurveLinear(tr, extremes=(0, 0.314, 6371, 7871),\r\n                                        grid_locator1=grid_locator1,\r\n                                        grid_locator2=grid_locator2,\r\n                                        tick_formatter1=tick_formatter1,\r\n                                        tick_formatter2=tick_formatter2,)\r\n\r\nax1 = floating_axes.FloatingSubplot(fig, 111, grid_helper=grid_helper)\r\nax1.invert_xaxis()\r\nfig.add_subplot(ax1, transform=tr)\r\n\r\nhoriz   = [Size.Scaled(1.0)]\r\nvert    = [Size.Scaled(1.0)]\r\nax0_div = Divider(fig,[0.0, 0.5, 1.0, 0.45],horiz,vert,aspect=False) # Rectangular Coordinates\r\nax1_div = Divider(fig,[0.0, 0.0, 1.0, 0.45],horiz,vert,aspect=False) # Curvilinear Coordinates\r\n\r\nax0_loc = ax0_div.new_locator(nx=0,ny=0) # Rectangular Coordinates\r\nax1_loc = ax1_div.new_locator(nx=0,ny=0) # Curvilinear Coordinates\r\n\r\nax0.set_axes_locator(ax0_loc) # Rectangular Coordinates\r\nax1.set_axes_locator(ax1_loc) # Curvilinear Coordinates\r\n\r\nfig.savefig('bug_report.png',bbox_inches='tight')\r\n```\r\n\r\n**Actual outcome**\r\n\r\n![bug_report](https://user-images.githubusercontent.com/1831182/113084188-7f883480-91ab-11eb-90b2-35b559d71e38.png)\r\n\r\n**Expected outcome**\r\n\r\nI expected to be able to stretch the curvilinear coordinate system so that its x-axis is aligned with the rectangular coordinate system. \r\n\r\n**Matplotlib version**\r\n  * Operating system: Ubuntu 18.04 LTS\r\n  * Matplotlib version: 3.3.4\r\n  * Matplotlib backend: Qt5Agg\r\n  * Python version: 3.7.7 (default, May  7 2020, 21:25:33) [GCC 7.3.0]\r\n\r\nMatplotlib installed with anacond default linux installer.\r\n\r\n","author":{"url":"https://github.com/w2naf","@type":"Person","name":"w2naf"},"datePublished":"2021-03-31T03:03:27.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":21},"url":"https://github.com/19832/matplotlib/issues/19832"}
