ok there are properties to set the minimum, maximum, and interval of all of the scales associated with a chart. they are located something like the following:
chart1.ChartAreas(ChartAreaName).AxisX.Mimimum
chart1.ChartAreas(ChartAreaName).AxisX.Maximum
chart1.ChartAreas(ChartAreaName).AxisX.Interval
chart1.ChartAreas(ChartAreaName).AxisY.Mimimum
chart1.ChartAreas(ChartAreaName).AxisY.Maximum
chart1.ChartAreas(ChartAreaName).AxisY.Interval
you can use those combined with the dimensions of your chart to display any kind of scale you would like.
