我将图片添加到我的 LaTeX 文档中,并在每张图片上添加一个 PGFplot,显示拍摄照片时的环境条件(图表)。我有上述环境条件的时间序列(例如测量温度)。
下面是一个最小的示例代码,但显然还不够完美。现在,我想要实现的是:
- 定义一个名为 say 的方法
\includegraphicswithpgf
,以便当 LaTeX 放置我的图片时,它还会在同一张图片上绘制一个小的 PGF 图(长度的 1/3 和高度的 1/3),使用给定的格式标记、刻度、颜色等。绘制曲线的数值数据以正确格式保存在 tiem-series 中(文本文件,包含两列:时间和温度),存储在给定位置(待定义)。 - 生成的 pgfplot 的 x 限制(即时间窗口)应根据我拍摄照片的文件夹自动调整。换句话说,
xmin
和xmax
应根据文件夹名称(例如,Photos/January 或 Photos/June)而不同。范围等于 xmax-xmin,应可手动调整并以给定(默认)日期为中心。 - PGF 图与图像周长之间的偏移量应根据图像大小自动重新调整。
我对 LaTeX 编程(方法定义)不太在行。如能得到任何帮助,我将不胜感激。非常感谢您愿意提供的任何帮助。

答案1
据我所知,控制轴的宽度和高度的唯一方法pgfplot
是使用width
和height
,并且pgfplot
将它们视为指导方针而不是规则。如果您想要精确,则需要使用\resizebox
。
