Custom Graph Properties Window
The View Properties window contains the following fields that control the general appearance of the custom graph.
- Caption. Enter the name of the custom graph.
- Floating. If enabled, it shows the custom graph as a floating window outside the main application window.
- Active. Select this check box to enable the custom graph to load data for statistics.
- Enable event markers. Select this check box to enable event markers to appear in chart views.
- Chart. The chart view provides support for displaying the statistics in chart format. Refer to Chart View. You can choose the type of chart you want for the statistic from the options listed under Chart.
- Range. This window pane applies only to chart views. Range refers to the scaling type applied to statistics before they appear in a chart.
- Auto. Automatic scaling ensures that all statistics fit in a chart.
- Fixed. Fixed scaling means that no scaling is applied. Only statistics with values between the specified Min and Max values appear in a chart.
- Normalized. With Normalized scaling, the y-axis has a minimum value of 0 and a maximum value of 100. Each statistic is normalized; that is, each statistic is scaled individually to fit in a chart. The scaling factor that is used for each statistic appears in the data legend near the statistic's name.
- Chart Properties. This window pane applies only to chart views. It allows you to list long statistics names by using one of the following options:
- First part of name
- Last part of name
The custom graph records the history of the statistic views. The Data History option has two fields that set the time and the polling interval to capture the views with its timestamp:
History Interval. This field controls the time interval between loaded samples. For example, you can set the history interval to 30 minutes so that no matter what the test duration is, you can always view the statistics gathered over the last 30 minutes.
Polling Interval Multiple. This field records statistics with the value entered in the field multiplied by two. For example, if the statistics polling interval is 1, the custom graph records statistics at an interval of every 1 * 2 = 2 seconds. If you change the polling interval, all existing data in the custom graph is dropped. Every time you change the polling interval, the internal buffer is recreated and the data is reloaded.
