title: Scrolling does not work with ZedGraph
body: <p>I have a line chart in ZedGraph.
  The data is coming from serial port every second.
  The chart is running.
  But do not roll (scroll) on the X axis and is compressed in the left corner.
  I need the chart scroll from right to left and the date and time appear in the X axis</p>
