Data Series

The Data Series panel allows you to view and modify the data series used for a chart view, or define a new data series to be used by a chart.

The Data Series attributes are as follows. Some attributes may be locked in the case where the chart already has the attribute specified.

Domain - Specifies the field to be used for the independent axis used for this chart. If another data series exists for the current chart, this field is locked to match the existing domain value.
Range - Allows you to specify Range values to be used for this chart. The Available list shows all possible ranges. The Add button adds the ranges selected in the Available list to the data series. The Remove button removes the ranges selected in the Selected table from the data series. Use the dropdown menus in the Selected table to specify the color, background, and pattern of each range.
Type - Select the chart type (line or bar with variations).
Breakdown - Each distinct value of the chosen breakdown field will produce a unique data series which represents all of the range values for that breakdown value. This is the mechanism used to create individual data series for each unique job on a system over time. For example, given the following data set:
Table 1. Data set example
Interval Number Job CPU Job Name

1 10 Job A

1 15 Job B

2 20 Job A

2 30 Job B

3 30 Job A

3 45 Job B

A line chart with a domain of Interval Number and a range of Job CPU, would result with the following data points: (1, 10), (1, 15), (2, 20), (2, 30), (3, 30), (3, 45).

Specifying a breakdown dimension of Job Name, would produce two lines with the following data points: Series 1 = (1, 10), (2, 20), (3, 30) and Series 2 = (1, 15), (2, 30), (3, 45).

It is a complicated, but powerful feature that may take a little experimenting to fully understand.
Tooltip fields - By selecting fields from this list, each point in the data series will include in its tool tip the value of the fields you select for the current domain.

Table 1. Data set example
Interval Number	Job CPU	Job Name
1	10	Job A
1	15	Job B
2	20	Job A
2	30	Job B
3	30	Job A
3	45	Job B

The data series functions are only available for chart views. It may be necessary to add a data series when switching from a table view to a chart view. If you try to select the action "Show as chart" while viewing a table that has does not have a data series defined, this action will require you to define a data series before continuing.
