调整 pgfplots 以使其美观：边距、边界、对齐

Question

我创建了以下图表，但我觉得它不太美观。我有一些想法，想让它看起来更好（如下图所示），但我不知道如何实现。有人可以告诉我如何进行这些修改，或者忽略我的想法，但提供一个使图表更具视觉吸引力的替代示例吗？

• 将图例中的文字左对齐，而不是居中
• 图形是正方形而非矩形，且不包含半正方形（包含正确代码 0-2）
• 线条更粗/更明显
• 图表左右延伸未超出所用 X 值的范围（从 1 开始，到 10 结束）
• Y 轴标签距离图表左侧不太远

。

有时做事会有几种方法，mvienney 的指点很有帮助。

您是否知道PGFplots 手册，它更加有用，并且充满了示例？您询问的所有内容都包含在该文档中。
