This menu contains options that enable you to edit the trend view's display and comparison settings.
To access |
On the trend view, click the Open edit menu button |
User interface elements are described below:
UI Elements |
Description |
---|---|
3D Mode (stacked bar chart view only) |
Enables you to view the chart in 3D. |
Color Trends (table view only) |
Activates the trend report's threshold settings. For details about thresholds, see Create trend reports. |
Compare to Baseline/Previous (table view only) |
Enables you to change the comparison method displayed in the trend view. For details on comparison methods, see Create trend reports. |
Delete this Trend View |
Deletes the trend view. |
Do not Show Difference (table view only) |
Enables you to hide value differentials between test runs. It is recommended to use this setting when exporting the report to a CSV format. |
Edit Display Setting |
Enables you to change the appearance of the trend view. The available settings are:
|
Edit Trend View Title |
Enables you to edit the trend view title. |
Export to CSV (table view only) |
Enables you to export the report to a CSV format. |
Select Measurements |
Opens the Measurements Configuration dialog box, which enables you to add measurements to the trend view. For user interface details, see Measurements Configuration dialog box. |
Show Difference as Value/Percentage (table view only) |
Enables you to define how to display value differentials between test runs in the trend view - as values or as percentages. |
Show Values (stacked bar chart view only) |
Enables you to view the measurement values on the actual bar columns. |

User interface elements are described below (unlabeled elements are shown in angle brackets):
UI Elements |
Description |
---|---|
<Measurement value name> |
The name of the measurement value being trended, for example, minimum, maximum, average, and so on. |
<Measurement value> |
The actual value of the measurement being trended, and its comparison value, displayed per test run. For details about comparison methods, see Create trend reports. |
Name |
The name of the measurement being compared. |
Type |
The type of measurement being compared. |

This section explains the Line Graph trend view display setting.
User interface elements are described below (unlabeled elements are shown in angle brackets):
UI Elements |
Description |
---|---|
<graph slope> |
The upward or downward slope of the line represents an upward or downward change in the measurement's unit. For example, a higher transaction response time (which is a performance regression), or a higher transactions per second value (which is a performance improvement). |
<x-axis> |
Lists the test runs according to their run date. |
<y-axis> |
The relevant unit of measurement. Example: For the Transaction Response Time measurement, the y-axis values represent seconds, while for the transactions per second measurement, the values represent the number of transactions. |
V |
Determines whether the measurement is visible. All measurements are displayed by default. Clear the check box to hide a measurement. |
B |
Displays the measurement in bold. |
C |
Displays the color of the measurement as it appears in the graph. Click the colored square in the column to select a different color for the measurement. |
Type |
Contains an acronym that identifies the measurement type. For a full list of available acronyms, see Measurement acronyms. |
Function |
Displays the value of the measurement being trended. |
Scale |
Indicates the scale of the measurement. When viewing information in the line graph view, you can adjust the scale of any measurement to make comparing measurements more meaningful. To change the scale of a measurement, click the value in the column and select the desired scale from the Set Scale box that opens. You can also apply the selected scale to all the measurements in the graph. |
Name |
The name of the measurement. |

User interface elements are described below (unlabeled elements are shown in angle brackets):
UI Elements |
Description |
---|---|
<bar height> |
The height of the bar represents the change in the measurement's unit. For example, a higher transaction response time, which represents a performance regression, or a higher transactions per second value, which represents a performance improvement. |
<x-axis> |
Lists the test runs according to their run date. |
<y-axis> |
The relevant unit of measurement. Example: For the Transaction Response Time measurement, the y-axis values represent seconds, while for the transactions per second measurement, the values represent the number of transactions. |
C |
Displays the color of the measurement as it appears in the graph. Click the colored square in the column to select a different color for the measurement. |
