平均能量损失

Question

这是我第一次使用 pgf 时的后续问题。现在图表已经达到了我想要的效果，但看起来还不够完美。我试着用手册弄清楚，但是……

• 是否可以在过长的标签中添加换行符（可能是自动的）？
• 可以格式化文本吗？当我使用 textbf 时，出现了错误
• 如何更改每个条形的颜色。我发现的唯一解决方案是删除文本标签

谢谢所有 tikz 专家提前致谢 :)

Answer 1

• 使用every node near coord/.style={text width=3 cm,},您可以设置文本节点的宽度。
• 添加fill=color如\addplot：\addplot+[ybar, fill=red] plot....改变颜色。
• 您可以通过以下方式使字体加粗every node near coord/.style={font=\bfseries},

您还可以通过 进行更多更改every node near coord/.style。例如，如果您不喜欢文本左对齐，但希望其居中，则添加align=center。
