Changing Chart Settings

The Settings tab of a chart enables you to modify the chart by changing various chart settings.

• You can filter your Load Session data results in various ways. You can filter the results displayed in your chart by selecting specific scripts or measurements within your Load Session, by applying time or statistics-based time filters. For example, you can focus your chart on a specific script or time segment within the Load Session data and/or specify a threshold for one or more of the statistics used in the selected Load Session (such as Hits per second > 50). This enables you to produce charts that contain only the information you wish to present.
• You can also modify various chart parameters such as the time format, tolerance range, etc.

After you modify a chart’s settings, click or to regenerate the chart.

   The selected scripts are added to your chart settings. To regenerate the chart with the new settings, click .

Selecting Measurements for Interactive Chart

In an interactive chart, you can select specific measurements from all or specific scripts. By default, charts are generated for all the measurements of a Load Session.

To select measurements:

1. Select the chart in the Charts area.

2. Click the Settings tab of the chart.

3. Click the Measurement Selection section. The Measurement Selection area appears.

   Note: If any changes are made to the measurements selection, an asterisk (*) is displayed besides Measurement Selection in the section’s title.

4. Select the measurements to include in your chart. Total is selected by default and indicates that the report will be generated for all the Load Session’s scripts.

5. Select a value for the X-axis of the graph:

   • Time – Shows the selected measurements over time. In the Parameters section described inModifying Chart Parameters, you can edit the Time Format parameter and set it to one of the following values:
     • Relative seconds – Shows the selected measurements over time. The time is displayed as the number of seconds that elapsed from the beginning of the test (20, 40, 60, 80, 120, etc.).
     • Relative time – Shows the selected measurements over time. The time is displayed as the time that passed from the beginning of the test (00:20, 00:40, 01:00, 01:20, etc.).
     • Absolute time – Shows the real time, starting from the time at the beginning of the test (17:31:40, 17:32:00, 17:32:20, …).
   • Load Size – Shows the change in selected measurements over the Load Size measurement. For example, if you select the 'Response Time’ measurement, then Response Time over Load Size shows the response times in different load sizes, regardless of when the measurement was received.
   • Percentile – Shows all the percentile values of the selected measurement(s). For example, the 90th percentile means that 90% of measurements are smaller than this value, and 10% are larger than this value.
   • Summary – Shows the sum (such as the average value) of the selected measurements.
   • Other – Shows the selected measurement(s) over any measurement of your choice. For example, 'Response Time over Content Size' shows the variations in the response time, based on the size of the response, regardless of time/load size.

   The selected measurements are added to your chart settings. To regenerate the chart with the new settings, click .

Filtering by Time

Reports are generated for the entire Load Session by default. Use the Time Filter to remove the beginning or end of a Load Session or focus on a specific window of Load Session time. If the template you are using does not support this filter, the Time Filter section is disabled.

To change the Load Session time range:

1. Select the chart in the Charts area.

2. Click the Settings tab of the chart.

3. Click the Time Filter section. The Time Filter appears.

   

   Notes:

   • If any changes are made to this filter, an asterisk (*) is displayed besides Time Filter in the section’s title.
   • You can enable or disable the Time Filter by selecting or clearing the Filter Enabled checkbox. When this checkbox is cleared, "(Disabled)" is displayed in the Time Filter section.

4. Use the slider to change the Load Session start and end times. The number of seconds and the actual dates and times are displayed as you move the slider.

Only the Load Session data from the time specified is used to generate the report.

To clear the Time Filter:

• In the Time Filter area, click . The Time Filter defaults are restored in the From and To fields. By default, the entire duration of the Load Session is displayed.

To regenerate the chart with the new settings, click .

Filtering by Statistics based Time

The statistics-based time filter enables you to specify a numeric filter for each of the statistics in the Load Session. This filter filters out segments of a chart based on their time. However, in contrast to the time filter, data is only filtered if it matches the specified condition. You can specify a numeric filter for multiple statistics and connect them using logical connectors, such as match all or any of the conditions. If the template you are using does not support this filter, the Statistics-based Time Filter section is disabled.

Note: The actual statistics are not filtered by this filter. For example, if your Load Session contains the following statistics and you filter by Load Size being greater than or equal to five, your chart will display the last three time segments only (from 40 to 80):

Time	Load Size
20	1
40	5
60	10
80	15

Note: For an explanation of the statistics and their meanings, see the WebLOAD Console User Guide.

To add a filter to a specific statistic:

1. Select the chart in the Charts area.

2. Click the Settings tab of the chart.

3. Click the Statistics-based Time Filter section. The Statistics-based Time Filter area appears.

   

   Notes:

   • If any changes are made to this filter, an asterisk (*) is displayed beside Statistics-based Time Filter in the section’s title.
   • You can enable or disable the Statistics-based Time Filter by selecting or clearing the Filter Enabled checkbox. When this checkbox is cleared, "(Disabled)" is displayed in the Time Filter section.
