This chart is helpful in ensuring that operators are collecting data at the correct times. Unlike a standard control chart, the Time Axis Chart scales the X-axis by a fixed interval of the date/time stamp on data records.
Note: The finest resolution for date/time stamps on a Time Axis Chart is one minute. This means that a data record with a date/time stamp containing more than 00 seconds will be displayed as data entered in the following minute. This could cause unexpected results when displaying a Time Axis Chart of data that is differentiated by the "seconds" portion of the date/time stamp. |
