5.10.3 Notes on combination reports
- Organization of this subsection
(1) Graph types and graph options
The Show 3D graph option can be set for any graph, but is ignored for graph types other than column or stacked column.
You can also set the Show Grid option for any graph, but it only applies to the graph in the foreground.
(2) Order in which graphs are drawn
The graphs in a combination report are drawn in the following order:
-
Series groups are drawn in order from the first series group, with subsequent series groups being drawn over the earlier ones.
-
Registered reports in a series group are displayed in the order in which the report is registered in the series group, with subsequent registered reports being drawn over the top of the earlier ones.
-
Fields in a registered report are displayed in the order in which they appear in the report, with subsequent fields being drawn over the top of the earlier ones.
The following figure describes the order in which graphs are drawn.
The specific order for 1. and 2. above is determined by the series group settings you specify when defining the combination bookmark. Make sure that the settings you specify do not cause graphs to become hidden behind other graphs. The order of the fields described in 3. is determined by the settings in the window where you created or edited the report definition.
When a series group contains 3D clustered column/3D stacked column graphs or line graphs, any group can be displayed in the foreground regardless of the order of the series groups. You can specify which graph to display in the foreground in the <foregroundCombinationGraph> tag of the initialization file (config.xml).
The following table describes the order in which graphs are drawn for each value of the <foregroundCombinationGraph> tag.
Value of <foregroundCombinationGraph> tag |

For details, see the section describing the <foregroundCombinationGraph> tag of the initialization file (config.xml) in the appendixes of the manual JP1/Performance Management Reference.
(3) Horizontal axis (X-axis) and vertical axis (Y-axis) of graphs
-
You cannot use common settings that apply across the entire combination report.
For the Y-axis of each series group in a combination report, you can use either automatic scale adjustment (where the axis is adjusted to the maximum and minimum values of the actual data) or manual scale adjustment (where the maximum and minimum values are specified by the user). You can also choose whether to display the axis label on the left or right side of the graph.
-
The X-axis for a combination report is a single fixed time series.
Data collected over a date range or with an interval that does not match the X-axis is assumed to be missing some information and the system attempts to compensate it. This might compromise the integrity of the graph. If a misalignment in the collection interval occurs when PD records are collected, a stacked graph might not be displayed normally. We recommend that you use a line graph when the data includes PD records.
To avoid this, you can use an optional PFM - Web Console function to adjust the record collection time for the graph display. For details, see the description of the <graph-time-correction> tag of the Windows configuration file (config.xml) in an appendix of the manual JP1/Performance Management Reference.
-
The order of the Y axis scales for a combination report matches the order in which the graphs are drawn.
Of the series groups in a combination report, the Y axis scale associated with the series group in the foreground is drawn closest to the graph. Each subsequent Y axis scale is drawn in order on the outside of the previous scale.
(4) Number of fields in a report
-
Although there are no restrictions on the number of fields in a combination report, the system might be unable to display the graph or legend in part or in its entirety when the report contains too many fields. In this case, either increase the magnification of the graph, or use the following methods to restrict the number of fields displayed in the graph (we recommend that graphs display no more than approximately 20 fields).
-
Edit the combination bookmark to remove some of the reports from the graph.
-
Edit the report definitions to contain fewer fields, and then recreate the registered reports.
-
Edit the report definitions to apply filter conditions, and then recreate the registered reports.
-
Recreate the registered reports using shorter display names for the fields than the default field names.
If the following parameters are exceeded, the system might be unable to display the graph or legend in part or in its entirety, or the legend might be displayed over two or more lines.
-
100% magnification: Legend approx. 20 lines
-
200% magnification: Legend approx. 30 lines
-
400% magnification: Legend approx. 50 lines
-
600% magnification: Legend approx. 50 lines
-
800% magnification: Legend approx. 70 lines
-
-
When the legend for a combination report contains too many characters, part of the legend might be cut off. In this case, either increase the magnification of the graph, or use the following methods to restrict the number of characters displayed in the legend.
-
Shorten the report names and then recreate the registered reports.
-
Recreate the registered reports using shorter display names for the fields than the default field names.
-
Reduce the number of bound agents and then recreate the registered reports.
If the following parameters are exceeded, the system might be unable to display the legend in its entirety:
-
100% magnification: Legend approx. 50 double byte or 80 single byte characters
-
200% magnification: Legend approx. 80 double byte or 120 single byte characters
-
400% magnification: Legend approx. 110 double byte or 160 single byte characters
-
600% magnification: Legend approx. 140 double byte or 200 single byte characters
-
800% magnification: Legend approx. 160 double byte or 230 single byte characters
-
(5) Series group settings
-
At least one registered report must be assigned to a series group. No graph is displayed if none of the series groups contain any registered reports, or when the combination bookmark contains only a baseline.
-
If the name of a series group in a combination report contains a large number of characters, the series group name and legend might overlap. You can resolve this issue by increasing the magnification of the graph or reducing the number of characters in the series group name.
For example, in a graph where a series group name contains approximately 25 double-byte or 30 single-byte characters and the legend contains approximately 10 lines, the series group name and legend can overlap when the magnification is at 100%. You can eliminate the overlap by increasing the magnification to 200% or more.
(6) Date range of reports
When you set the date range of a report to a Within the past ... option (for example Within the past hour), the report is updated with the data from that time period up to the present time when you choose Refresh in the View Report window. The start time of the baseline remains unchanged.
If you choose Specify when displayed as the date range, the Start time and End time set for the report and the start time of the baseline remain unchanged when you choose Refresh in the View Report window.
(7) Baseline display periods
-
The Start time setting for the baseline display period is determined automatically based on the current time when the combination report was started and the Date range and Report interval settings for the report display period. When you change these settings, the Start time setting for the baseline display period is set to the Start time setting for the report display period.
-
When you choose Refresh in the View Report window, the Start time and End time of the settings for the report display period might change according to the Date range setting. However, the Start time setting for the baseline display period will remain unchanged.
-
Changes to the Start time setting for the baseline display period or the baseline data do not affect the starting points and ending points of graphs created from combination reports. However, when the report displayed with the baseline contains only one piece of data (data with the same starting point and ending point), the graph's starting point and ending point might be set to the range of the data collected as the baseline. The starting point and ending point of the actual display period for the graph is determined based on the data present in the range from the Start time to the End time in the report display period settings.
-
The Start time setting for the baseline display period applies to the individual baseline. When a baseline contains data from multiple fields each with different start times, the field data with the earliest start time in the time series after the Start time setting for the baseline display period serves as the starting point. All other fields are displayed according to the start times determined when the baseline data was saved.
-
When data from multiple fields with different start times is registered as a baseline, the graph is drawn with the field data earliest in the time series after the Start time setting for the baseline display period serving as the starting point. In this case, the relative start positions of each subsequent field are preserved.
(8) Length of graph titles
You can display a maximum of 64 single or double byte characters in a graph title. However, when the magnification is 100%, a title that contains more than 60 double-byte characters might be displayed over two lines. The title will be displayed on one line if the characters are single byte.
(9) Displaying PD type records
In PFM - Web Console version 10-00 or later, the following can occur when you display PD type records in a clustered column or stacked column graph:
-
The column width can become narrow when there are inconsistencies in the record collection interval.
-
If the record collection interval is one hour or longer, the position of the column can differ from the same graph in versions of PFM - Web Console earlier than 10-00.
For this reason, we recommend that you use a line graph when displaying PD type records in a combination report in PFM - Web Console 10-00 and later.
