When using an mscombi2d chart with y-axis values:
 
	        'AxisMinValue: 0, 
	        yAxisMaxValue: someOddValue
 
	The zero value for the y-axis is not displayed. If the yAxisMaxValue is even then it is displayed. In fact this happens whenever the scale is not a multiple of the gap, ie: min: 0, max 13.
