Charts in Neptune

Neptune app displays all logged numerical series, that is FloatSeries attributes, as charts. You can analyze the logged metadata in the following ways:

Change graph plotting order​

To control which graphs are plotted in the foreground, change the order of the runs in the runs table. Graphs are drawn from top to bottom:

  • The topmost run is plotted in the background and the bottom-most run in the foreground.
  • When visualizing run sets in a report, the leftmost set is plotted in the foreground.

Highlighting data​

When you hover over a metric in a chart, the graphs are highlighted in the following way:

  • In single run mode or when there's one run selected:

    • The metric that you hover over is highlighted in all charts in your current view.
    • For example, when you hover over accuracy in one chart, this metric is highlighted in all charts where accuracy is plotted.

  • In compare mode with multiple runs selected:

    • The run and the metric that you hover over are highlighted in the chart that you're interacting with. In other charts, all metrics of the run that you hover over are highlighted.
    • For example, when you hover over the accuracy of the astute-kittiwake run in a chart, this metric and this run are highlighted. At the same time, all metrics of the astute-kittiwake run are highlighted in other charts in your current view.

Highlighting outliers​

To help you identify outliers, the error bands in charts have visually distinct borders.

For details, see Show borders around error bands.

Show or hide inherited datapoints​

By default, charts include metrics inherited from ancestor runs. To show or hide the history:

  1. From the runs table toolbar, access Controls.
  2. Enable or disable Show inherited datapoints.

All runs tab in the Neptune app. The buttons for switching metric history on and off are highlighted.

For details, see Show or hide inherited datapoints.

Zoom in charts​

To zoom in, click and drag over an area of the chart.

You have two ways to zoom out:

  • To zoom out by a factor of 2, double-click anywhere on the chart.
  • To reset the zoom, triple-click anywhere on the chart.

The zoom applies to all charts that share the same X-axis series in your current view.

To zoom in or out on a single chart, hold Ctrl or Cmd while interacting with the chart.

Change zoom-out behavior

The default zoom is an experimental feature. You can change it so that double-clicking anywhere on the chart resets the zoom instead of zooming out.

To disable the experimental zoom:

  1. In your account settings, go to Experimental features.
  2. Disable Double-click to zoom out.
