Example 2 with TmfStatisticsViewer

use of org.eclipse.tracecompass.internal.tmf.ui.viewers.statistics.TmfStatisticsViewer in project tracecompass by tracecompass.

 * It uses the extension point that defines the statistics viewer to build

 * created, since the global viewer already contains all the basic
 * statistics. If there is no trace selected, a global statistics viewer will
 * still be created.
