# Trend views

A trend view is a display item that presents trending information for a particular performance metric, for example, transaction response time.

To access | From the LoadRunner Enterprise navigation toolbar, click and select Performance Trending (under Analysis). On the Performance Trending page, in the Trend Reports grid, click the name of the report to open. The report opens as an additional tab on the LoadRunner Enterprise Dashboard. The trend view tabs are displayed by default. Trend Views are contained within the trend view tabs. The trend view tabs are displayed by default.

Edit Trend View Menu

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 (not available in the Trend Overview tab).

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: Table view. This view is best suited for displaying comparisons between measurements. You can view threshold settings in this view only. For details, see Display Setting: Table. Line graph view. This view is best suited for displaying trending information graphically over a timeline. For details, see Display Setting: Line Graph. Stacked bar chart view. This view displays trending information graphically over a timeline. It is best suited for trending a small number of multiple measurements. For details, see Display Setting: Stacked.
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.

Display Setting: Table

This section explains the Table trend view display setting.

To access | On the trend view, click Open edit menu button (not available in the Trend Overview tab). Select Edit Display Setting. In the Edit Display Setting dialog box, select Table.
Important information | You can view threshold settings in table view only.

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.

Display Setting: Line Graph

This section explains the Line Graph trend view display setting.

To access | On the trend view, click the Open edit menu button (not available in the Trend Overview tab). Select Edit Display Setting. In the Edit Display Setting dialog box, select Line.
Important information | When you hold the cursor over the line graph, a tooltip appears displaying the exact amount of units for that measurement, correct to the nearest test run on the timeline. In other words, if you hold the cursor near the left point of the line graph, you see the value of the first test run. When you click a section in the line graph/measurement in the legend, it becomes highlighted, as does the corresponding section in the legend/line graph.

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.

Display Setting: Stacked

This section explains the Stacked Bar Chart trend view display setting.

To access | On the trend view, click the Open edit menu button (not available in the Trend Overview tab). Select Edit Display Setting. In the Edit Display Setting dialog box, select Stacked.
Important information | If different values are selected for the same measurement (for example, Maximum and Average transaction response times), then the measurements appear as stacked bars. That is, the values appear above each other for the bar that represents the transaction response time measurement for a specific test run. When you hold the cursor over a bar, a tooltip appears which displays the exact number of units for that measurement, correct for that test run. When you click a section in the bar chart/measurement in the legend, it becomes highlighted, as does the corresponding section in the legend/bar chart.

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.
V | Determines whether the measurement is visible. All measurements are displayed by default. Clear the check box to hide a 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.
