Once the basis for filtering has been defined, individual attribute filters can be created:

• Use the button to create a new attribute filter.
• Click on the symbol to link attribute filters.

To select an instance attribute, expand the Field selection list.

For key indicators on the y-axis the aggregation required can be set using a selection list. An exception here is the number of processes as aggregating these is not appropriate.

The choices available are:

• number
• total
• average
• minimum
• maximum

To use an attribute, drag it from the list onto the area of ​​the corresponding axis. Only instance attributes with the matching symbol can be dragged onto the corresponding axis.

If instance attributes of differing levels are mixed, the resulting chart is not meaningful. The wizard therefore displays the following message:

You have combined process level attributes with step level attributes. This allocation does not lead to meaningful results.

Please change your selection of instance attributes. Attributes which match are highlighted in color.

A green frame signals to the user that they are saving the selected instance attribute in the correct axis area.

You can determine which instance attributes should be displayed in the chart in the axis allocation step. The instance attributes available are listed on the left.

The two areas for the content of the x and y axis are located on the right hand side of the pop-up window.

• Dimensions are displayed on the x-axis. They are marked with the symbol .
• Key indicators are displayed on the y-axis. They can be identified by the symbol.

In distribution charts (all chart types except tachometer), key indicators can also be displayed as a dimension on the x-axis.

The correct allocation of dimensions and key indicators is visually supported. If the user tries to place an instance attribute on the wrong axis, the area will be framed in red.

The unit of time can be set for time-based dimensions. This is applicable to the following instance attributes:

• end date
• last update
• start date

The following units of time can be set:

• year
• month
• day
• hour
• minute
• second

In the first field, the selection list is the basis for determining filtering:

• All: All rules must be met.
• Any: At least one rule must be met.

Example: Step contains %end%

All instances containing the string end in the step instance attribute will be displayed. Steps in which additional characters appear before or after the string end are also taken into account.

If you change the option on the create following filter function, the filter entry is displayed.

Duration periods (process duration, step duration) are entered as whole numbers. A single number is interpreted as meaning a time unit of seconds.

After completing the entry, the time units applied are written out automatically.

If a time unit entry is not clearly defined, a corresponding message will be shown.

If the contains operator is used, wildcards can be used for entries in the value field. The following placeholders are allowed:

• _ (underscore): An underscore can be used as a placeholder for any character.
• % (percentage sign): The percentage sign can be used as a placeholder for any set of character strings.

A distinction is made between four groups of instance attributes and the operators belonging to them:

Operators	Instance Attributes	Value Input
	Current step End event Host Process name Process ID Start event Step	manual input* * Except when operators is defined / not defined
	Process time Step duration Process count	manual input* * Except when operators is defined / not defined
	End date Last update Start date	Calendar (date picker) and manual input of the time * * Except when operators is defined / not defined and relative filtering If relative filtering is selected, the following options are available via an additional selection list: last minute last hour last day last week last month last year user-defined (manual input, see relative filtering )
	Event Steps	Manual input

Depending on the instance attribute selected, various operators become subsequently available. The operators available can be displayed via a selection list.

Weeks, days, hours and minutes can also be entered using the corresponding abbreviations:

The use the abbreviation h for the entry of hours as a unit of time is preferable in order to avoid confusion with the entry of seconds (s).

If an operator was selected, the related value can be entered.
