Graph

In the graph to the left of the “Graph and statistics” page, plots of selected data are presented. Initially, no plots are included in the graph, only vertical markers for each garbage collect. At the top of each garbage collect marker, there is a number, either 0, 1, or 2, that represents the generation of the garbage collect.

The graph always contains one x-axis, representing the time elapsed since starting the profiler session. Additionally, it contains zero or more y-axes, which are added when plots are added to the graph. When a plot is added, it must have a y-axis matching its unit. If no matching y-axis exists, a new one is added. For example, adding “Total instances” to an empty graph will add a y-axis with the text “Instances.” Adding “Live instances” to the same graph will not cause another y-axis to be added, since both “Total instances” and “Live instances” are using the unit “Instances.” However, adding “Total bytes,” will cause a y-axis with the text “Bytes” to be added.

To add plots to the graph, perform one of the options below:

1.   Check one of the checkboxes in the statistics to the right.

2.   Use the real-time Types/Resources view to include data from a type or resource by checking the checkbox in the Graph column for the desired type or resource. Once the Graph checkbox is checked, a checkbox will appear at the top left in the Graph and Statistics page. This checkbox can be used to select whether plot(s) for the type or resource should be included in the graph. To the right of the type/resource checkboxes, there is another set of checkboxes. These checkboxes allow you to select the specific plots you want to add for the selected types and resources. Plots of one or more of the values can be selected:

•      Total instances

•      Live instances

If dispose info is not being shown, the following plots are also available:

•      Total bytes

•      Live bytes

•      Allocs/sec

•      Bytes/sec

If dispose info is being shown, the following plots are available instead.

•      Disposed instances

•      Undisposed instances

A description of the above values is given in the description of Real-time Types/Resources.

The colored line to the left of the checkboxes indicates the color the plot will be when included. For more information on working with the graph, see Working with the Graph.
