pgfplots-当逗号分隔符定义为空时，如何使用带有逗号的图形？

正如 MWE 所示，由于第一列代表年份，每 1000 个计数的分隔符被定义为空（因为缺乏更好的术语）。

因此运行 MWE 不起作用，因为 pgfplots 不会解析带有,1000 个分隔符/指示符的数字。我有点困惑，想确认这是否是正确的想法：输入文件中的每个数字是否都应该只由数字组成，而没有任何其他字符？

数据01.csv

2006;50,000
2007;100,000

数据02.csv

2006;100000
2007;150000

您只应将此 1000 的分隔符定义应用于打印 x 轴上的刻度标记。对于此用途x tick label style或等效用途xticklabel style。无论如何，这不会影响从输入文件中读取。为此，您可以pgf通过选项来忽略逗号ignore chars：

我已向 添加了compat设置pgfplots，并将其替换ymin=0为ymin=10，以抑制警告。
