This attribute is an array of X data values to be entered into the trace designated by CURRENT TRACE. These X values will be matched up with Y values supplied by the Y DATA attribute. Nothing will happen to the value of X DATA if, when you try to set it, SHARED X mode is on and CURRENT TRACE is not equal to 1.
If you try to set the X DATA array with an array smaller than the value of POINT CAPACITY for the trace, X DATA will accept all of the values from the smaller array. If you try to set the X DATA array with an array larger than the value of POINT CAPACITY for the trace, X DATA will accept the low-index values from the larger array and the highest-index values will be lost.
