In this article, we're assuming that you've already read Getting Started with the Analysis view.

1. Charts with multiple Components

All Components in a project that records Statistics can be found in the components menu in the left toolbar, along with all the configured Assertions and Server Monitors.

A Chart can contain several Components (or Assertions and Server Monitors). When dragging a Component from the toolbar, you have two options on where to drop it. Dropping it to an existing Chart 1_snag_evi will add the Component to the Chart. Dropping it on an empty part of the area to the right 2_snag_evi will create a new Chart containing that Component.

Components can be dragged to both existing Charts and to an empty part of the grey area.

All Components contained in a Chart will be represented by an icon. Notice that the two icons in the image below are stacked on top of each other 1_snag_evi:

A stack of two Component icons showing on a Chart (1). The Components panel is expanded below with two radiobuttons representing the two Components (2).

When adding a Statistic to a Chart containing multiple Components, the first thing that you'll have to chose is which Component you want to add a Statistic from 2_snag_evi.

To remove a Component from a Chart, toggle the Component panel and drag the Component's sub chart to the black hole.

2. Global Statistics

In the Globals menu in the left toolbar, you will find the current Project among with all TestCases. These can be used in Charts in the same way as Components to e.g. show Statistics for the whole Project.

3. Chart panels

panelBar

At the bottom of a Chart, there are seven 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. This chapter will explain the different panels briefly; for a more complete reference, see the Charts Reference page.

3.1. Components

A Chart (1) expanded by Components. The sub charts are marked with (2) and (3). The sub charts show one Statistic each, while the main Chart shows both of these Statistics.The Components panel shows the Statistics of the Chart categorised by Component (actually also TestCase and Project). 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 1_snag_evi containing two Components have its Component panel toggled. The two sub charts 2_snag_evi 3_snag_evi show the Statistics from each contained Component.

3.2. Agents

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 too see if any Statistics differs a lot between Agents.

3.3. Add statistic

Lets you chose a Statistic to add to the Chart. Learn more about which Statistics that can be added from which Components in the Statistics Reference.

3.4. Zoom

Sets the horizontal (time) zoom level. The All level always shows everything. How many seconds that each datapoint is an aggregate of is documented here.

The zoom panel with buttons for the zoom levels: All, Weeks, Days, Hours, Minutes and Seconds.

3.5. Scale

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.

3.6. Style

This panel contains options for line thickness, dash type, and color.

The Style panel showing widgets for styling the appearance of two Statistics.

3.7. Raw data

From this panel, you can export the raw data showing in a Chart to a CSV-file. 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

3.8. The resizing handle

Grabbing this handle will resize the Chart vertically:

4. Templates

analysisMenu

The Templates menu in the left toolbar contains a set of predefined charts for analysis. For example, the Bytes Throughput Analysis will create a Chart containing all Components and VU Scenarios (as well as the current Project).

To add a Template, simple drag it to the empty area to the right.

percentileAnalysis

A Request Percentile Analysis.

5. Tabs

The Analysis view can have several Tabs, 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 General is created by default when you create a new project. A new tab can be created by clicking the New Page button:

newPage

...the new tab can then be renamed by right clicking it:

renamePage

Tabs can be reordered by dragging and dropping them.

6. Reporting

During or after a run, you can click this button to create a printable report:

The reporting button.

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).

A sample report.

7. Comparing Results

Results can be compared in the same Chart. This can be done for old Results, as well as in realtime for the current run. Read more about this in Comparing Results.
