Timeseries Chart Configuration

I need help with some problems in a timeseries chart:

  • The chart include a space in both side (red circles in images). I would like delete this space and maximize the graphic area.
  • The X-Axis only show one line. I put this: HH:mm
    dd.MM.YY in “Date Format” but only show one line. Can I set up two lines?

I send images.

Anyone can help me?
