plot customization problem

[richard wan]

hi, everyone, I am new to pygraph, and when i customize my plotwidget i find something that confuse me very much. I follow the example tutorial to customize my own, and the confusion is there too in the example.
See the following screen-shot. I am confused that what is that in the red circle, is that a map scale or something like that? how can I hide that? why there is no that thing when i do not customize
the bottom axis?
Thanks a lot?
