Elements

This section contains a single Data series element by default. It allows you to specify a data series to be plotted and monitored in this chart.

Tip: You can have more than one data series in this chart. Add additional Data series elements from the Creatable elements pane.

This section also allows you to add:

  • One or two Sidechart elements to have statistical characteristics, such as mean and standard deviation of data series, displayed next to the main chart.
  • One or more Intervals elements to have confidence intervals displayed for every individual data point in the chart.

This element has the following attributes:

End event

Select the event that marks the end of the time period from the drop-down list on the right.

Tip: You can enter a time instead. Select the End time option from the drop-down list on the left.

End time

Enter the End time to specify the end of the time period.

Tip: You can select an event instead. Select the End event option from the drop-down list on the left.

This element has the following attributes:

Data type Multiplicity Usage Default value

Estimate SD based on

Select the method to be used to estimate the standard deviation.

The following options are available from the drop-down list:

  • Mean observation: Uses the formula of the corrected sample standard deviation to calculate the SD.
  • Moving range: Uses the following to calculate the SD.

    mean ( MR ) = 1 m i m | x i + 1 - x i |

    where

    m
    is the number of observations of the data series minus 1

    SD = mean ( MR ) d 2

Note: Estimation of the standard deviation based on the moving range statistic (MR) is recommended as best practice for Shewhart I-charts by USP <1010>, Appendix 1. The value of
d 2
is equal to 1.128. The number is also known as Hartley's constant.

Event

This section allows you to specify an individual event that may affect the data you want to monitor in this Control chart document.

This element has the following attributes:

Data type Multiplicity Usage Default value
Node 1...unbounded optional none

Context:

/Control chart/Events/

Event time

Automatically inserts the current date and time when you click the input box of the element. You can enter a different date and time.

Tip: You can reference this event as Start event and/ or End event in the rule sets of this document (Rule sets > Rule set > Scope: Time interval > Start event/ End event).

This element has the following attributes:

Data type Multiplicity Usage Default value
xs:dateTime 1...1 required none

Context:

/Control chart/Events/Event/

Events

This section allows you to specify events that may affect the data you want to monitor in this Control chart document. You can then reference these events in rule sets and have them visualized in the charts of this document. For each event you want to specify, you set up a separate Event element. When you add the Events section to the document, it contains a single Event element, but you can add as many as you need. An example of events that may affect the data you want to monitor would be the introduction of new cell cultures. In this case, you set up events for the dates on which you change cell cultures. You can then reference these events in rule sets and distinguish specific time periods to be monitored and visualized in charts.

Intervals

This section allows you to specify data from the dataset/ Data table to be applied as upper and lower boundaries of confidence intervals for the data points in this chart. To define the upper and lower boundaries, you select two columns of the dataset/ Data table from the drop-down lists in this section. You can view Data table columns in the References editor (Observation source: Aggregation) or in the Observations editor (Observation source: User input).

Tip: You can have more than one definition of confidence intervals in this chart. Add additional Intevals elements from the Creatable elements pane.
