强制将堆叠条形图中的最后两个条形向下

我想使用 ShareLaTeX 中的 tikz 以堆叠条形图来说明数据。我正在处理两个文件：一个名为“按类型划分的众筹价值.txt”的数据文件和我正在处理的文档“Crowdfunding.tex”。我有包含前三年不同类型众筹的数据，但只有过去两年的总价值。txt 文件中的数据如下所示：

year Donation Equity Lending Reward Mixed-others Total

2010 460.4 49.9 316.5 15.7 0 
2011 675.7 88.9 554.9 61.5 0
2012 979.4 115.7 1169.7 383.3 2.4
2013 0 0 0 0 0 6100
2014 0 0 0 0 0 16200

我在其中用 0 来表示不同类型。（还尝试用“。”替换 0 来强制最后两个条形，但没有成功。目前输出如下所示：

我想要完成四件事：1）强制将两个黄色条形图设置为 0 美元十亿 = 02）将标签展开到一行3）移除上部和顶部轴（因此只保留标记的轴4）在最后两个条形图内插入标签（2013 年的条形图为 6,2，2014 年的条形图为 16,2）。

这是我的代码：

我被困住了！任何帮助我都感激不尽。谢谢。

答案1

您收到一条错误消息，提示某些行缺少列。如果我0在 2011、2012 和 2013 年的最后一列（总计）中添加，黄色条将从 bn=0 开始。

如果图例只有一行，请使用

legend columns=-1,

如果取消注释代码中的以下两行，则可以删除顶部和右侧轴

axis x line* = bottom,
axis y line* = left,

或者如果你插入

axis lines*=left,

要nodes near coords仅获取黄色条，请使用ymax=17000和

\addplot+[fill=yellow, draw = yellow,
    nodes near coords,point meta=explicit% <- added
  ] table[x=year, y=Total,
    meta expr=\thisrow{Total}/1000% <- added
  ] {data.txt};

更新（因为对这个答案的评论）

nodes near coords改变使用的颜色

nodes near coords style={text=black}

并将y值除以 1000，使用

y 表达式=\thisrow{}/1000

对于每一个情节。当然你ytick也必须改变。
