问题

以下是翻译好的代码部分：

我有一个包含国家、年份和数值的数据框。

我已经为该数据设置了一个索引：

```python
data = data.set_index(data['Country or Area'])
data.drop(['Country or Area'], axis=1, inplace=True)
data.head()

我尝试创建一个类似这样的简单图表：

%matplotlib inline
albania = data.loc['Albania']
ax = albania[['Year', 'Value']].plot(kind='bar', figsize=(8,5), title="Albania 1990年至2015年的降水量")
ax.set_ylabel("降水量")
ax.set_xlabel("年份")

然而，条形图显示的y轴标签是'Albania'的索引名称，这是不正确的。它应该显示年份范围。

如有其他需要，请随时提问。

I have a dataframe with list of countries, years and values.

I&#39;ve set an index for that data:

data = data.set_index(data['Country or Area'])
data.drop(['Country or Area'], axis=1, inplace=True)
data.head()

I'm trying to create a simple plot like this:

%matplotlib inline
albania = data.loc['Albania']
ax = albania[['Year','Value']].plot(kind='bar', figsize=(8,5), title="Precipitation of Albania between 1990 and 2015")
ax.set_ylabel("Precipitation")
ax.set_xlabel("Years")

However, the bar shows y_labels with the index name 'Albania', which is not correct. It should show the range of years.

What should I do to change the labels to the correct one?

**得分**: 1

ax.set_xticklabels(albania['Year']) 这将把所有的x轴刻度标签设置为一系列年份。

    ax.set_xticklabels(albania[&#39;Year&#39;])

This will set all your x-tick labels to a range of years
