When zero alignment is in effect, the chart will be rendered with its primary, linear, numeric axis range starting at zero, as opposed to the minimum data value present in the DataSource.
This property does not apply to non-numeric (for instance, axes based on dates or discrete item labels) or non-continuous axes (for instance, logarithmic axes for which log 0 is mathematically undefined).
Developers can use this feature when they want their minimum data values to display and showing the axis at the origin is relevant. When there is little variation between data values (i.e., the difference between the maximum and minimum values being charted is small compared to the minimum value's difference from the zero-axis), it is a better choice to adjust the RangeAxisType to Custom on the AxisAppearance and set the RangeMin and RangeMax properties instead of using zero-alignment.
