DateFormatter","articleBody":"### Bug summary\r\n\r\nWhen I set `rcParams['text.usetex'] = True`, I can't skip line in date format. \r\n\r\nFor example, I can't use `DateFormatter('%d/%m\\n%Y')`.\r\n\r\nRemoving the skip line `\\n` it works: `'%d/%m\\n%Y' --\u003e '%d/%m/%Y'`.\r\n\r\nIt was working before. It's stopped working since my last update/upgrade of Anaconda.\r\n\r\n### Code for reproduction\r\n\r\n```python\r\nimport matplotlib as mpl\r\nimport matplotlib.pyplot as plt\r\nimport matplotlib.dates as dates\r\n\r\nmpl.rcParams['axes.labelsize'] = 15\r\nmpl.rcParams['figure.figsize'] = [12, 3]\r\n\r\nmpl.rcParams['text.usetex']   = True\r\n# mpl.rcParams['text.usetex']  = False\r\n\r\nFMT = dates.DateFormatter('%d/%m\\n%Y')\r\n# FMT = dates.DateFormatter('%d/%m/%Y')\r\nplt.axes().xaxis.set_major_formatter( FMT )\r\n\r\nplt.show()\r\n```\r\n\r\n\r\n### Actual outcome\r\n\r\n```\r\n---------------------------------------------------------------------------\r\nCalledProcessError                        Traceback (most recent call last)\r\n~/BIN/ANACONDA3_2021.11/lib/python3.9/site-packages/matplotlib/texmanager.py in _run_checked_subprocess(self, command, tex, cwd)\r\n    232         try:\r\n--\u003e 233             report = subprocess.check_output(\r\n    234                 command, cwd=cwd if cwd is not None else self.texcache,\r\n\r\n~/BIN/ANACONDA3_2021.11/lib/python3.9/subprocess.py in check_output(timeout, *popenargs, **kwargs)\r\n    423 \r\n--\u003e 424     return run(*popenargs, stdout=PIPE, timeout=timeout, check=True,\r\n    425                **kwargs).stdout\r\n\r\n~/BIN/ANACONDA3_2021.11/lib/python3.9/subprocess.py in run(input, capture_output, timeout, check, *popenargs, **kwargs)\r\n    527         if check and retcode:\r\n--\u003e 528             raise CalledProcessError(retcode, process.args,\r\n    529                                      output=stdout, stderr=stderr)\r\n\r\nCalledProcessError: Command '['latex', '-interaction=nonstopmode', '--halt-on-error', '../09efec18b9a3c1b4d23927d49f15f25f.tex']' returned non-zero exit status 1.\r\n\r\nThe above exception was the direct cause of the following exception:\r\n\r\nRuntimeError                              Traceback (most recent call last)\r\n~/BIN/ANACONDA3_2021.11/lib/python3.9/site-packages/IPython/core/formatters.py in __call__(self, obj)\r\n    339                 pass\r\n    340             else:\r\n--\u003e 341                 return printer(obj)\r\n    342             #
