图表上的图例

以下代码使图例显示在图表上（并且图表的尺寸太小）：

我该如何解决这个问题？谢谢

答案1

您可以通过轴选项width=<width>和缩放图形height=<height>。另一种可能性是\resizebox {\textwidth}{\height}在 内使用wrapfigure。请记住 也会\resizebox缩放 内的字体大小tikzpicture。不过，如果您使用这些解决方案，wrapfigure您还必须注意其宽度。

您可以使用以下方式调整图例的位置legend style={at={(<x>,<y>)},anchor=<name>}

输出wrapfigure和轴选项：
