Custom dashboard offer several workflows when viewing chart details.
Click a tile in a custom dashboard to get a page-sized view and interact with the graph. Click the dashboard name in the breadcrumb trail to return to the dashboard.
The data in the Details view is automatically refreshed every 5 minutes.
Different charts allow for different types of interactivity. Depending on the chart type, you can:
- View data point details.
- Change time range and data bucketing.
- View graphical and/or tabular data.
- Change the chart type on the fly.
- Drill down into the raw scatter plot, and from there, the objects list, object graph, and waterfall graph.
- Export a chart image.
View data point details
Hover over a node or chart segment to view data point details. The details depend on the chart type and the measure. The details pop-up is not available for Gauge charts.
Change the time range and resolution
When viewing a chart, you can change the time range for the entire custom dashboard. However, the change does not not apply to tiles with a tile-specific time range.
Select a time range from the controls at top right. See Custom Dashboards for details on choosing a relative or absolute time range).
You can change the resolution (data bucketing) for a chart. Click the resolution drop-down list to choose an interval. Note that the intervals available depend on the time range of the dashboard or tile.
View chart and/or table
When viewing a chart, you can opt to view the selected test and metrics (with optional splitting) in graphical and/or tabular format—click the drop-down list at top-right. By default, both the chart and table are displayed.
The table lists the tests and splitting factors, if any, and the average metric values during the selected time range. If you change the time range, the averages are automatically recalculated.
Uncheck a series in the legend or table to remove it from the graph.
You cannot uncheck series when viewing the Meter and Gauge charts.
Change the chart type
When viewing chart details, you can change the chart type on the fly to visualize data differently. For example, if viewing trend lines for performance (total time) split by page, you can switch to a Pie or Meter chart to compare the average values for the same metric. Or you might want to change a trend chart to a raw scatter chart.
Click the chart type icon at top left to select a different chart type; the current type is highlighted.
- You cannot change the tile type when viewing the Synthetic Tests tile.
- When switching from a dual-axis chart type, note that only metrics from the left y-axis are graphed in other chart types that do not support two y axes.
- When switching from a chart with many series to the Gauge or Measure charts, note that only the first series is graphed; the Gauge and Measure charts only support one series.
- Be aware that not all chart types are suitable for the data selected. For example, if you are viewing trend lines for performance in different cities (i.e., total time split by city), switching to a pie chart is not meaningful, as performance times in different cities do not constitute parts of a whole.
Raw scatter plot, object list, object chart, and waterfall
You can drill down to a raw scatter plot from the Details view for most chart types. Click a data point, then click the Raw scatter link in data point details.
The Raw scatter link is not available from the Pie, Meter, and Gauge chart types.
The scatter plot displays every test run that was aggregated in the selected data point. For example, if the parent chart's resolution is 48 hours with data bucketing of 4 hours and you select a data point timestamped 12:00, the scatter chart displays every test run for the time range 12:00 - 15:59.
In the scatter chart, hold the mouse pointer over a data point to display a pop-up window with information such as the metric name, test name, metric value, timestamp, and number of elements and bytes downloaded.
The Raw Scatter view includes data tables in two tabs:
The default Summary tab (shown in the figures above) lists the series (test or test and splitting factor) and the average values for the charted metric.
The Details table lists the timestamp, test name, and metric value for each data point.
Drilling down from the raw scatter plot
In the Summary tab:
Click Objects to drill down to the comprehensive list of all objects downloaded in all the data points shown in the raw scatter plot. Objects are listed by URL and the test page on which they are found.
In the Chart object list, select one or more objects and click Chart to view the Object chart. (You don't need to hold down the Ctrl or Shift key to select multiple objects. A selected object stays selected until you click it again.)
The Object chart displays a trend line chart for each selected object for the same metric shown in the raw scatter plot. A table lists each object's average metric value over the time range.
From the Details tab, click Summary to view a data point's test summary page, from where you can drill down to a Waterfall graph for any page.
Export the chart
To export the chart as an image file, click the Download icon at top right and select either Export to PNG (SD) or Export to PNG (HD).
