I want to draw barplot, like the code:\r\n\r\n```\r\nimport pandas as pd\r\nimport proplot as plot\r\ndf = pd.DataFrame({'a': [0,1], 'date':[pd.to_datetime('2017-04-01'), pd.to_datetime('2017-04-02')]})\r\nf, axs = plot.subplots(ncols=1, figsize=(12, 6))\r\naxs[0].bar(df['date'], df['a'])\r\naxs.format(title=\"TEST\", xlabel='x axis', ylabel='y axis',\r\n           large=20, small=10, xlocator='year', xminorlocator='month', xformatter='%Y')\r\n```\r\n\r\nbut I get the fellowing error. So did i do anything wrong. Thanks very much.\r\n\r\n```\r\n---------------------------------------------------------------------------\r\nTypeError                                 Traceback (most recent call last)\r\n\u003cipython-input-83-7ba278c889ae\u003e in \u003cmodule\u003e\r\n      2 df = pd.DataFrame({'a': [0,1], 'date':[pd.to_datetime('2017-04-01'), pd.to_datetime('2017-04-02')]})\r\n      3 f, axs = plot.subplots(ncols=1, figsize=(12, 6))\r\n----\u003e 4 axs[0].bar(df['date'], df['a'])\r\n      5 axs.format(title=\"TEST\", xlabel='x axis', ylabel='y axis',\r\n      6            large=20, small=10, xlocator='year', xminorlocator='month', xformatter='%Y')\r\n\r\n~/anaconda3/lib/python3.7/site-packages/proplot/wrappers.py in _wrapper(self, *args, **kwargs)\r\n   3081         @functools.wraps(func)\r\n   3082         def _wrapper(self, *args, **kwargs):\r\n-\u003e 3083             return driver(self, func, *args, **kwargs)\r\n   3084         name = func.__name__\r\n   3085         if name not in proplot_methods:\r\n\r\n~/anaconda3/lib/python3.7/site-packages/proplot/wrappers.py in bar_wrapper(self, func, x, height, width, bottom, left, vert, orientation, stacked, lw, linewidth, edgecolor, **kwargs)\r\n   1166         linewidth=lw, edgecolor=edgecolor,\r\n   1167         stacked=stacked, orientation=orientation,\r\n-\u003e 1168         **kwargs\r\n   1169     )\r\n   1170 \r\n\r\n~/anaconda3/lib/python3.7/site-packages/proplot/wrappers.py in _wrapper(self, *args, **kwargs)\r\n   3081         @functools.wraps(func)\r\n   3082         def _wrapper(self, *args, **kwargs):\r\n-\u003e 3083             return driver(self, func, *args, **kwargs)\r\n   3084         name = func.__name__\r\n   3085         if name not in proplot_methods:\r\n\r\n~/anaconda3/lib/python3.7/site-packages/proplot/wrappers.py in standardize_1d(self, func, *args, **kwargs)\r\n    328     # WARNING: For some functions, e.g. boxplot and violinplot, we *require*\r\n    329     # cycle_changer is also applied so it can strip 'x' input.\r\n--\u003e 330     return func(self, x, *ys, *args, **kwargs)\r\n    331 \r\n    332 \r\n\r\n~/anaconda3/lib/python3.7/site-packages/proplot/wrappers.py in _wrapper(self, *args, **kwargs)\r\n   3081         @functools.wraps(func)\r\n   3082         def _wrapper(self, *args, **kwargs):\r\n-\u003e 3083             return driver(self, func, *args, **kwargs)\r\n   3084         name = func.__name__\r\n   3085         if name not in proplot_methods:\r\n\r\n~/anaconda3/lib/python3.7/site-packages/proplot/wrappers.py in add_errorbars(self, func, medians, means, boxes, bars, boxdata, bardata, boxstd, barstd, boxmarker, boxmarkercolor, boxrange, barrange, boxcolor, barcolor, boxlw, barlw, capsize, boxzorder, barzorder, *args, **kwargs)\r\n    822     else:\r\n    823         xy = (x, iy)  # just the stats\r\n--\u003e 824     obj = func(self, *xy, *args, **kwargs)\r\n    825     if not boxes and not bars:\r\n    826         return obj\r\n\r\n~/anaconda3/lib/python3.7/site-packages/proplot/wrappers.py in _wrapper(self, *args, **kwargs)\r\n   3081         @functools.wraps(func)\r\n   3082         def _wrapper(self, *args, **kwargs):\r\n-\u003e 3083             return driver(self, func, *args, **kwargs)\r\n   3084         name = func.__name__\r\n   3085         if name not in proplot_methods:\r\n\r\n~/anaconda3/lib/python3.7/site-packages/proplot/wrappers.py in cycle_changer(self, func, cycle, cycle_kw, label, labels, values, legend, legend_kw, colorbar, colorbar_kw, *args, **kwargs)\r\n   1662         if name in ('bar',):  # adjust\r\n   1663             if not stacked:\r\n-\u003e 1664                 ix = x + (i -
