Customize the graph display

This topic describes how to adjust granularity, select the chart format, and control the appearance of the individual points plotted in the graph. You can customize the display of graphs and measurements in your test run so that you can view the data displayed in the most effective way possible.

Change the granularity of the data

You can make the graphs easier to read and analyze by changing the granularity (scale) of the x-axis. The lower the granularity, the more detailed the results.

To set granularity:

  1. Select a graph and click Set Granularity. The Granularity dialog box opens.

  2. Enter the granularity of the x-axis and select a time measurement. The maximum granularity is half of the graph's time range.

  3. To apply the same granularity to all graphs, select Reduce for all graphs.

  4. Click OK.

    Note: To ensure readability and clarity, OneAnalysis automatically adjusts the minimum granularity of graphs with ranges of 500 seconds or more.

    If this gran changes, it can affect performance.

Example

In the following example, the Hits per Second graph is displayed using different granularities. The y-axis represents the number of hits per second within the granularity interval. For a granularity of 1, the y-axis shows the number of hits per second for each one second period of the test.

For a granularity of 5, the y-axis shows the number of hits per second for every five-second period of the test.

Similarly, a granularity of 10 shows the number of hits per second for every ten-second period of the test.

The lower the granularity, the more detailed the results. For example, using a low granularity as in the upper graph, you see the intervals in which no hits occurred. It is useful to use a higher granularity to study the overall Vuser behavior throughout the scenario.

Customize graph appearance

You can select the graph display and control the appearance of the individual points plotted in the graph.

  1. Select a graph and click Graph Display. The Graph Display dialog box opens.

  2. Choose the chart format for a graph:

       
    Line and Points Switches the chart format to a line and point chart.
    Line Switches the chart format to a line chart.
    Points Switches the chart format to a point chart.
    Columns Switches the chart format to a stacked column chart.
    Area

    Switches the chart format to a stacked area chart.

    Grid

    Switches the chart format to a data grid. You can filter and sort by each entity type.

  3. Assign colors to measurements.

    You can apply color preferences to make specific transactions more recognizable.

    1. In the measurements grid, select a transaction and click its color icon.

    2. Select a color from the drop-down list and click OK. The color is applied to the transaction.

  4. Show or hide measurements.

    You can determine the measurements that are displayed in the graph by selecting a transaction in the grid and clicking the display measurement icon ( indicates the measurement is hidden).

Enlarge a section of the graph

To zoom in or enlarge a section of the graph, move and hold down the left mouse button over the section of the graph you want to enlarge.

Click Reset zoom to restore the default graph size.
