问Python画图问题，总出现警告，怎么解决呢？

import pandas as pd

import pandas_alive

import matplotlib.pyplot as plt

import matplotlib.ticker as mticker

plt.style.use('ggplot')

elec_df=pd.read_csv("D:\Aus_Elec_Gen_1980_2018.csv",index_col=0,parse_dates=[0],thousands=',')

#缺省值0填充、绘图

ax_main=elec_df.fillna(0).plot_animated(

'electricity-generated-australia.gif',

period_fmt="%d/%m/%Y",

title='Australian Electricity Sources 1980-2018',

perpendicular_bar_func='mean',

cmap='Set1',

n_isible=5,

orientation='h',)

最终警告：

d:\Users\zhang\Anaconda3\lib\site-packages\pandas_alive\charts.py:221: UserWarning: FixedFormatter should only be used together with FixedLocator

ax.set_yticklabels(self.df.columns)

d:\Users\zhang\Anaconda3\lib\site-packages\pandas_alive\charts.py:222: UserWarning: FixedFormatter should only be used together with FixedLocator

ax.set_xticklabels([max_val] * len(ax.get_xticks()))

请问怎么解决呢
