void ShowMeanMarker( <boolean bShow1StdDev> )
void ShowMeanMarker( boolean bShow1StdDev <, boolean bShow2StdDev> )
boolean bShow1StdDev
If bShow1StdDev is true, a mean marker extending one standard deviation from the mean is displayed. If bShow1StdDev is false, the mean marker is hidden.
boolean bShow2StdDev
If bShow2StdDev is true, a mean marker extending two standard deviations from the mean is displayed. If bShow2StdDev is false, the mean marker is hidden.
This method shows or hides mean markers. A mean marker indicates the mean value of the data and shows the extent of one or two standard deviations from the mean. Calling this method without a parameter is equivalent to calling it with bShow1StdDev equal to true and bShow2StdDev equal to false.
