5.7.5 Using Autolabel to check data values
Performance Management can display tooltips that indicate the value of a graph plot when you rest your mouse pointer on the plot. This functionality is called Autolabel. You can enable the Autolabel functionality by selecting the Show AutoLabel check box on the Display report settings page of the View Report window.
To automatically enable Autolabel when you display a report, specify true for the enableAutoLabelAtDefaultDisp parameter in the initialization file (config.xml). For details on the initialization file (config.xml), see the description of the file in the manual JP1/Performance Management Reference.
The following figure shows an example of a View Report window in which a tooltip is displayed by the Autolabel functionality.

- Note
-
You cannot use the Autolabel functionality with the following graphs:
-
Graphs in the print window
-
Graphs in reports output in HTML format by the jpcrpt command
-
Graphs in the Tiling Display window
-
Graphs in the System Operational Status Summary window
-
- Note:
-
If using the automatic label function, the width and height of the area that can be specified by the mouse pointer might become extremely small, the plots might overlap in a line graph, and the tool tips by the autolabel function might not be displayed.
In this case, use another Web browser. Alternatively, perform any of the following operations to increase the size of the area that can be specified by the mouse pointer:
-
Reduce the number of selected fields.
-
Reduce the number of displayed instances.
-
Reduce the report display period.
-
Specify a larger zoom magnification.
The following is an example of reducing the report display period for an area graph.
For example, the Process Trend report for PFM - Agent is displayed under the following conditions:
-
Report display period: Within the past day (24 hours)
-
Report interval: Minutes
-
Graph type: Area
In this case, specify about 3 hours for the report display period to display the autolabel tool tips.
-
The following describes how to set the number of digits displayed in the data in a tooltip, and describes the settings needed to use Autolabel with graphs that have a large number of plots.
- Organization of this subsection
(1) Setting the number of digits in tooltips
By default, the maximum number of digits in a tooltip displayed by the Autolabel functionality is seven before the decimal point, and three after. To change these limits, set values in the autoLabelMaxIntegerDigits and autoLabelMaxFractionDigits parameters (both under the <draw> tag) in config.xml.
For details on the initialization file (config.xml), see the description of the file in the appendixes of the manual JP1/Performance Management Reference.
(2) Using Autolabel for graphs with a large number of plots
The Autolabel functionality can display data in tooltips for a maximum of 1,440 plots. You can change the number of plots for which the Autolabel functionality can display tooltips by changing the value of the maxAutoLabelPoints parameter under the <draw> tag of config.xml.
For details on the initialization file (config.xml), see the description of the file in the appendixes of the manual JP1/Performance Management Reference.
