In this article, we're assuming that you've already read our Statistics Basic Tutorial.
0.1. Global Statistics
In the Global menu in the left toolbar of the Statistics Tab, you will find the current Project as well as all your different scenarios. These can be used in Charts in the same way as Components to e.g. show Statistics for the whole Project. Just drag any of these items into the charts area to create a new chart.
0.2. Chart panels
At the bottom of a Chart, there are a few buttons. These will all toggle panels appearing from the bottom of the Chart. Don't be afraid to explore these, as the actual toggle panel buttons won't perform any action other than showing/hiding information. This chapter will explain the different panels briefly; for a more complete reference, see the Charts Reference page.
The Expand panel shows the Statistics of the Chart categorised by Component. Each Component is shown in a separate sub chart. All changes made to the sub chart will be reflected in the main chart, and vice versa.
In the image to the right, a Chart containing two Components have its Component panel toggled. The two sub charts show the Statistics from each contained Component.
The Agents panel shows the Statistics of the Chart categorised by Agent. Each Agent is shown in a separate sub chart, which could be useful to see if any Statistics differs a lot between Agents. Notice that you will see this panel only in LoadUI Pro. Also, you must have agents configured in order to see anything in the Agents panel.
Sets the horizontal (time) zoom level. The All level will show a complete view of the test run, from the beginning to the latest data point. How datapoints are aggregated in order to generate a visually reliable chart is documented here.
Click on this button if you want to "follow" the chart as new data is collected.
0.7. Chart Options
Lets you scale a Statistic to be more comparable with others. If you for example want to see Response time (milliseconds) in the same chart as Bytes throughput (millions of bytes), it might be useful to scale down Bytes throughput by 0.0000000001. Scaling is done by simply multiplying the actual values with the specified scale.
0.9. Raw data
Clicking Export Raw Data in the chart's drop-down menu will save all the data in the Chart to a CSV-file. This feature is only available in LoadUI Pro.
Exported data has one Statistic per column, like this:
TIMESTAMP, MY_RUNNER~AGENT1~RESPONSE_SIZE~AVERAGE, PROJECT_3~FAILURES~TOTAL 00:00:00, 12076, 0 00:00:01, 12290, 0 00:00:02, 11901, 0 00:00:03, 4088, 1
The Statistics Tab can have several tabs itself, just as your favourite web browser. Tabs are useful if you are short on screen space or want to categorize your charts.
A tab called Untitled Page is created by default when you create a new project. A new tab can be created by clicking the plus button:
...the new tab can then be renamed by right clicking it:
During or after a run, you can click this button to create a printable report:
This will bring up a dialog where you can select which pages that you want to include in the report. Reports can be printed or saved as a file (e.g. PDF).
0.12. Comparing Results
Test runs can be compared in the same chart. This can be done for old test runs, as well as in realtime for the current run. Read more about this in Comparing Results.
